Road resurfacing during the daytime without stopping traffic [video]
- CarVac 2y agoI wish they showed the mobile bridge in motion.
- 2024throwaway 2y agoExtremely cool video. Very cool technique as well. Two questions. First, I'm guessing the cardboard boxes they filled with road material are for testing / QA of the blend? Second, the "bridge" structure that allows traffic to keep flowing is very cool, but I'm assuming you have to stop traffic to get it into place to begin with. Seems unlikely they are moving that structure while traffic drives over it. Of course placing that structure should take much less time than the resurfacing process, but how much time? Minutes? Hours?
- bombcar 2y agoIt's probably overnight to set it in position, but it looks like it has wheels so they can probably move it down the road in an overnight hour or so. It's basically a one-time capital cost for the "mobile bridge" and then they can use it repeatedly; not sure it really ends up being better overall than the usual American "divide and conquer" method used, where they do a lane at a time and divert traffic around. The denser the area the more valuable it'll be, I presume.

- 2024throwaway 2y agoSuper cool! Thanks for sharing.
- Aromasin 2y agoI love to see infrastructure jobs like this that don't interfere with people's daily lives. A similar feeling when I watch the Japanese build a subway in just 3 hours: https://www.youtube.com/watch?v=_BYW4YYqG5A https://www.youtube.com/watch?v=_BYW4YYqG5A Meanwhile, just down the road from me, we've had a major bridge closed since April of last year, and is due to reopen October 2024.... Videos like this should be a lesson to Civic planners everywhere.
- bobthepanda 2y agothis particular change took 3 hours. but generally speaking there were years of planning and other construction works that made a 3 hour switch even possible. Japanese rail projects aren't particularly fast. The subway line that was connected in this 3 hour switch started construction in 2001, finished in 2008, and the connection made in the video was completed in 2013. https://ja-m-wikipedia-org.translate.goog/wiki/%E6%9D%B1%E4%BA%AC%E3%83%A1%E3%83%88%E3%83%AD%E5%89%AF%E9%83%BD%E5%BF%83%E7%B7%9A?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en https://ja-m-wikipedia-org.translate.goog/wiki/%E6%9D%B1%E4%... This project for example started in 2006 and opened last year: https://en.wikipedia.org/wiki/Eastern_Kanagawa_Rail_Link https://en.wikipedia.org/wiki/Eastern_Kanagawa_Rail_Link --- One other thing that makes the 3 hour window possible is the sheer amount of manpower they throw at the problem during these three hours. the US does not have a project construction industry built around swarming, but rather maintaining a lower cost small crew at all times. One reason why there is so much construction in Japan is because the government has relied on fiscal stimulus to the point where it now has the highest debt-to-GDP in the world at a rate of 263%.
- bombcar 2y agoThe US can swarm when needed and paid for - usually when a major traffic artery is dead because of a disaster. IIRC it’s something like if a state can fix a damaged/destroyed freeway in under sixty days the feds pay for it entirely.
- sva_ 2y agoYou may like this video of a tunnel being built under a highway in one weekend: https://m.youtube.com/watch?v=btOE0rcKDC0 https://m.youtube.com/watch?v=btOE0rcKDC0
- Torkel 2y agoYes, please! To me it feels like 90% of road works I pass actually has nobody there working at all. Some go on for years it seems. Another option is what they do in Japan - just get 10X the number of people on it, with all the tools for the entire job and then do it all overnight. Also, nice to see good old "dude with shovel" in there, a tool that would have looked the same back in the 19th century.
- soco 2y agoAhh and I thought the forever-construction sites were a Swiss thing. Every 20 km or so you'd have 1-2 km of road construction signage where nothing happens for a couple of years. At some point it just disappears, to come up again a few km down the road. Nobody here to explain us the phenomenon?
- aidenn0 2y agoThere's an old joke that works almost everywhere: Have you heard about the new invention that will allow <insert name of local department for handling road work> to lay off 90% of its workers? A shovel that stands up by itself.
- blowski 2y agoI had an eccentric Maths teacher at school who used to stare out of the window and make odd claims. One was that he was running a roadworks business using telekinetic powers, and all the people in hi-vis jackets were merely scarecrows.
- stormdennis 2y agoWhere I live it goes crazy with road works when it's coming to the end of the year with the council trying to spend the unused budget rather than lose it.
- froddd 2y agoIn the UK roadwork sites usually remain much longer than it takes for the result to start deteriorating once they have finished.
- bizzleDawg 2y agoDoes anyone know how the full width of the carriageway gets surfaced in this setup? Perhaps lane closures on the left/right side (sequentially) after the centre portion has been resurfaced?
- wongarsu 2y agoThe bridge itself is wide enough to resurface one lane. But its wheels can move in any direction. So instead of driving forward to do the next section you can also drive three meters to the left or right to do another lane instead. In general the entire bridge is as maneuverable as a 230m structure can be. The individual segments are designed to articulate. So once it's set up you can move it around to any other patch of road surface in the area.
- comebhack 2y agoThere is some more detail on the bridge itself in this video: https://www.youtube.com/watch?v=8tpv6n1ykfA https://www.youtube.com/watch?v=8tpv6n1ykfA The bridge is assembled over 2 nights at a motorway exit (so traffic can bypass it by driving off and immediately back on to the road). During night 1 the two end ramps are assembled and attached together to make a short bridge. During night 2 the ramps are driven apart, the central section is built to reach the full length and the entire structure is driven to the final location. The entire length is 236 meters long providing a working length of 100 meters underneath. The assembled bridge can flex slightly at the joins between sections, and has a turning radius of 2 kilometers.
- MichaelZuo 2y agoHaving to stop traffic, and then redirect it into the one emergency lane, every time 100m is finished in order to advance seems like a huge disadvantage. If the road is anywhere close to max capacity this will cause traffic jams either way.
- leni536 2y agoI would think that merely repositioning can be done overnight.
- bobthepanda 2y agohence why the work requiring the stopping and redirecting happens at night.
- MichaelZuo 2y agoThey can only complete 100m once every 12 hours?
- bobthepanda 2y agowith minimal road disruption, though. at least where I live you'll often seen lane reductions measured in weeks for repaving.
- nefarious_ends 2y agoI can totally imagine a future version of this that slowly moves along the roadway and handles all the roadwork automatically.

- jeffbee 2y agoGeez, I hate having to watch Swiss infrastructure projects. Living in Zurich completely destroyed any residual respect for the way we build in America. Aside from this clever bridge, note how many and how extreme the differences are between what you see in this video and what you would witness watching an American repaving crew. They have a sufficient amount of labor on the job, compared to the 3 guys you would see on an American job. They all have uniform PPE, instead of jeans and t-shirts. Their equipment is clean and looks like it probably works. Site dumpers are appropriately scaled for the job. Bigger dump trucks are normal cabover trucks instead of insane brodozers. They actually use an sufficient quantity of binder, instead of skimping on it because American supervisors can't tell the difference. So many differences in culture.
- hindsightbias 2y agoYeah, but they use a gas blower! Probably w/o ear protection. /jealous American
- DiggyJohnson 2y agoWhat's wrong with non-uniform denim jeans on a construction site? Otherwise I take your point.
- mschuster91 2y agoPants are also a form of PPE. On such a site you want something resistant to cuts, heat/fire and probably also chemicals.
- DiggyJohnson 2y agoDoes denim not satisfy PPE requirements for most normal job sites? What non-specialized material is better than denim at the requirements you explained?
- mschuster91 2y agoDenim isn't chainsaw cut resistant at all, you need pants with a special kind of fiber filler that jams a chainsaw or blade.
- josefresco 2y agoWe try to avoid Boston traffic by driving at night and then we run into... night construction! There's basically no time when traffic is reasonable around Boston. I'm pretty certain if they gave this equipment to the Mass DOT they'd figure out how to modify it to negate any benefit. /rant
- bastardoperator 2y agoSame thing in California, but working at night is actually better for the workers when it comes to sun and breathing in exhaust fumes. This might be economical for what amounts to a two lane road, but we have freeways with 22 lanes (I5).
- pixl97 2y agoYou are traffic. Our dependence on car culture made this nightmare we exist in. You're ranting at the wrong group, they are just trying to get the most done in the least amount of time and disruption, hence lowest cost.
- eddd-ddde 2y agoI agree that cat centric life is awful. However "you are traffic" is not the whole picture, not all traffic is created equal. Some people are just naturally adept at making traffic.
- pixl97 2y agoBoth quality and quantity matter. Bad drivers can make traffic anytime, but if you a good driver leave the house at 5PM you are traffic.
- eddd-ddde 2y agoCorrect. That's the biggest downside of car infrastructure, we are bound(ed?) by the lowest common denominator. Once a slow car is blocking the way we just contribute to that same traffic.
- MisterTea 2y ago[flagged]
- stkdump 2y agoRight, in Europe there are no unions.
- swores 2y agoI know sarcasm can be an effective way of making a point, but on a global forum where plenty of people are likely to not have a clue what unions do or don't exist in Europe (not to mention most Europeans won't know much if anything about unions in European countries other than their own) it's worth not being sarcastic so that your comment can be understood by more than just the people who already know what you're saying.
- MisterTea 2y agoSo they all think and operate EXACTLY alike? This must be a joke. If I am wrong then prove it. This is the statement which I have heard a few times already and a cursory search for "unions blocking better road repair technology" in ddg yields these articles which bolsters my argument: Directly related: https://www.aei.org/economics/america-in-the-slow-lane-how-unions-and-lobbying-groups-are-ruining-us-transportation-infrastructure/ https://www.aei.org/economics/america-in-the-slow-lane-how-u...

- stkdump 2y agoSo unions block innovation by insisting the government pays union-level wages to construction workers. I can tell you what is the difference between unions in Europe and unions in the US. As far as I can tell, unions and paying fair wages are not blamed for lack of innovation in Europe. We do have a lot of news about the fight over wages, but for some reason this antagonist union bashing in the media and general population seems to still be an American phenomenon.
- Ringz 2y agoTranslated from one of the newest comments under the video: "Thank you for the courage of the engineers and responsible authority not to give up despite the (failed) first attempt and to dare a second improved attempt." In addition to the technical performance, there is an equally remarkable social performance.
- gnicholas 2y agoIs it strong enough to have all types of vehicles driving over it? Or are heavy machinery and semi trucks told to exit?
- binarymax 2y agoThe video showed semis with trailers riding it, but it was unclear if the weight rating was the same (can the trailer be fully loaded?).
- gnicholas 2y agoI wonder who has the liability if something goes wrong. I would want the government to be liable to drivers (and assume this would be the case). A private company would need to have tons of insurance to be able to cover the death/destruction that could be caused if it collapsed.
- red_admiral 2y agoAs far as I know the heaviest truck allowed on Swiss roads in the first place is around 40 metric tons (exceptional loads that require a permit not included), and the bridge can handle those.
- theptip 2y agoAmazing! Going further, I was recently wondering why we don’t just build two-layer (or higher) freeways in areas that have heavy congestion. “Express” lanes with fewer exits perhaps, to minimize transitions if that’s a problem.
- jonwachob91 2y agoPlenty of interstates have a two-tier lane system, one tier with lots of exits, and an expressway tier with fewer exits/entrances. That is not a new innovation. example: https://i4express.com/ https://i4express.com/

- toast0 2y agoPotholes are traffic calming devices you don't even have to pay to install.
- gpm 2y agoInstead you pay a lot more in vehicle maintenance, and you make bicycling extremely uncomfortable forcing more people into vehicles.
- toast0 2y agoThat's the case for most traffic calming, isn't it?
- gpm 2y agoNo? Most traffic calming is not designed to send sudden shocks through your vehicle that cause extra wear and tear.
- toast0 2y agoWikipedia says > Speed bumps (also called traffic thresholds, speed breakers or sleeping policemen) are a class of traffic calming devices that use vertical deflection to slow motor-vehicle traffic in order to improve safety conditions It's just a difference of degree of deflection.
- kube-system 2y ago1. they are being phased out in many locations because of that issue 2. there are many other types of traffic calming devices: https://en.wikipedia.org/wiki/Traffic_calming#Measures https://en.wikipedia.org/wiki/Traffic_calming#Measures
- amanda99 2y agoSeems kind of miserable to work under that bridge all day while trucks are driving over you?
- DiggyJohnson 2y agoIt doesn't sound perfectly pleasant but are you suggesting the noise it too loud or what? Construction work has never been comfortable, and frankly I'm wondering if the shade of the bridge outweights the chaos of having an active roadway above head.
- brainwad 2y agoA Swiss newspaper interviewed the workers - they said they liked it a lot more because a) they get to work regular hours but in the shade and b) they have more space, since the traffic goes above them. On a normal worksite they have barely a few metres, since the rest of the road has traffic flowing on it still. https://www.nzz.ch/schweiz/astra-bridge-so-funktioniert-die-innovative-schweizer-baustellenbruecke-ld.1825440 https://www.nzz.ch/schweiz/astra-bridge-so-funktioniert-die-...
- pirate787 2y agoMy concern for the workers is that the bridge traps the particulate matter from the stones and the VOCs from the asphalt. Like working in a mine.
- avar 2y agoIt's open on both sides, it's more like working under a tarp. They seem to be using proper PPE when appropriate, and not be covered in accumulated dust like mine workers.
- phyzome 2y agoI was mostly thinking of how incredibly loud it would be to do all that under a metal roof. Sure hope they've got solid hearing protection.
- lxe 2y agoDoes the US road construction process follow the same meticulous precision?
- gwbas1c 2y agoIt varies from state to state... Kinda like the EU, except that each state is still a sovereign country.
- HumblyTossed 2y agoThat's an emphatic no.
- jimnotgym 2y agoIn the UK, well England more than the rest of the UK, we have a system for reducing disruption on the roads during maintenance. We just let it go decades without any resurfacing.
- kylehotchkiss 2y agoGreat technique. Thankfully every vehicle model seems to increase in size, durability, and suspension capability to mitigate any negative side effects.
- swores 2y agoAnd the trend of increasing car sizes means increasing mass means increasing damage to roads :/
- nvarsj 2y agoThis made me laugh, given my horrendous bike journey today on roads filled with holes in London. I'm pretty sure most of the damage are from construction company lorries. I wonder why the gov doesn't just tax them for their usage/destruction of public roads, and fund repairs with that?
- justsomehnguy 2y ago> why the gov doesn't just tax them for their usage/destruction of public roads Because the lorry owners (construction and transportation co.) would bitch and fight tooth and nail against that, rise the transport costs and... everyone would claim the roads aren't repaired anyway. Source: living in a country what did exactly that. Oh, they bitched hard.
- alentred 2y agoSo, you are saying the very same lorries transporting the raw material for road resurfacing someplace else? That should one profitable business!

- maxglute 2y agoLooks like 2 lanes -> 1.5 lanes, does speed change approaching ramp?
- leejo 2y agoI've driven over a few of these in Switzerland the last couple (few?) years, none this length but they are used on the autoroute around the Lake Geneva area sometimes. The speed is dropped to 60km/h and enforced by way of speed cameras - I have seen plenty of cars being flashed in the approach to the ramps.
- hyperific 2y agoI would bet that working in the daytime means fewer workplace accidents and increased job satisfaction from workers.
- JKCalhoun 2y agoI remember something like this in Popular Mechanics magazine (or similar) back in the 70's or perhaps even earlier. It was one of their awesome "artist's concept" piece that depicted more of a proposal, or what we might call a pipe dream, ha ha. I wish I could find the depiction — it was a ramp with cars passing over just like that (a lot shorter however) that would drive very slowly along, paving as it went.
- flaburgan 2y agoIf all that energy could go in something useful like improving trains that would be amazing. Us wanting it or not, cars are something from the past.
- eps 2y agoWhen they first installed this contraption next to us, they messed up the incline. It was too steep so one of longer trailer trucks promptly got stuck on it ultimately doing just that - stopping all traffic on the highway. It was glorious. Also, the speed limit on these bypasses is 60 km/h, so they are halving the bandwidth and create massive congestions during peak hours. Probably the reason they stopped using them recently and just close the highway for few hours at night instead.
- duxup 2y agoYeah I would think you'd also have to organize warning / preventing unusual oversized loads from showing up and ... oh noes they don't fit.
- flakeoil 2y agoBut below the video they say they are using it again in April 2024.
- eps 2y agoNot in my area. Here they stopped.

- ummonk 2y agoBandwidth doesn't vary much with speed (since people tend to maintain the same 2 second gap from the car in front of them), except at low speeds where the nonzero size of each car becomes significant.
- fbdab103 2y ago
- vbezhenar 2y agoWhat're incentives for state to care about traffic? In my city they'd close road, do nothing for a month, then quickly patch in a few days and open road. They don't care about traffic jams and badly patched road requires repair every few years, which is a good thing for repair company, they always got a lot of work. Theoretically I understand that bad traffic results in bad economy and less taxes, but in reality those things are so far away from each other to not make any influence.
- pixl97 2y agoEither your local officials are incompetent, or the problems at hand are much more complicated than you're giving them credit for. When it comes to locals, they are much more apt to be voted out by not repairing potholes, then state/national levels where people tend to vote on party lines. But, back to your road issues, I'm guessing you missed the part where some underlying infrastructure has gone bad, water and sewer pipes the most common culprits were fixed. If traffic were allowed to drive over the problematic pipes it would have made the issue much worse much faster leading to the entire street getting dug up.
- folli 2y agoThis is in Switzerland, where the incentives for the government are usually a bit more efficiently aligned with the citizen's wishes.
- sschueller 2y agoThe government decided to dig a third tunnel in one case because they calculated the economic damage would be greater if they had to close one tunnel for several years than digging the 3rd. Also this 3rd tunnel will not be used after construction other than for emergency evacuation. The 3rd tunnel was only approved under condition that capacity will not be increased.

- ByThyGrace 2y agoI saw that and wondered if they were samples for analysis (of what? in cardboard boxes??).
- phyzome 2y agoIt's for quality assurance. You take samples of asphalt (in this case), concrete, etc. during construction and they get shipped off for analysis. I don't know what they do with the asphalt, but for concrete they do slump tests of the wet concrete and crush tests of cured samples. Probably other tests too. I'm guessing it's pretty rare for the results to come back as "tear it all out and start over", but... you'd sure want to know if that were the case!

- cryptonector 2y agoOk, this needs to be a thing everywhere.
- dottjt 2y agoThis is incredibly smart. Although the risk is that if the machine somehow gets damaged/malfunctions or if a car crashes into it, the setup can become more of a liability than a benefit.
- jmbwell 2y agoI've seen this in Texas, notably on I-35 through Austin and on I-10 east out near the state line. In sequence, single-file, all the machines needed to do the job, from milling the surface at the front to laying down the new blacktop, rolling it, and IIRC painting it. Just creeping up the highway. Pilot vehicles at the front and back to close/open the lane. Texas definitely throws money at the problem. Although lately they're optimizing their spend for larger checks to fewer contractors on bigger roads. Simplifies all the kickbacks I'm sure.
- aschla 2y agoI'd love to see one of these on each end of the arterial 4-lane streets of Chicago. When spring hits, fire them up and go from one end to the other in either direction. Potholes become a thing of the past. We're already used to overhead infrastructure with the L all over the city.

- doctorhandshake 2y agoBeyond the bridge, the thing that has me stunned here is the precision and cleanliness of the job site. Being from the north east of USA, I am used to seeing road construction sites in permanent disarray - materials everywhere, rough interfaces between work site and untouched road, filthy machines, trucks, uniforms, and tool, etc. Is this just pristine because it's for a promo video or is this the norm in some places?
- ndr 2y agoIt's stereotypically Swiss.
- fbdab103 2y agoProbably a lot different when you are working under a bridge with cars whizzing about your head. There is not a lot of margin for error or an abundance of space to leave extra equipment.
- MrOrelliOReilly 2y agoAs a someone born and raised in the Northeast now living in Switzerland I can confirm that the cleanliness, orderliness and array of machinery is indeed typical in Switzerland :D But don’t let this bridge promo fool you, you’re just as likely to deal with roads closed to construction as anywhere else… the cost of well functioning infrastructure is that they always seem to be working on it!
- dark-star 2y agoI bet they cannot set up that bridge without "stopping traffic completely". It needs to be built or at least moved to the target spot, during that time, traffic needs to be stopped. From a network engineer standpoint this sounds like false advertisement ;-) ("Your server can be moved to another rack non-disruptively. We just need to disconnect your network cable and connect it to another switch.") But still, this is pretty cool
- duxup 2y agoIt's like every redundancy type system I have seen, either for data storage, or network traffic, or applications. Yes, it does prevent a thing or helps to protect from it, very true from that point of view. Except now whatever is orchestrating that redundancy is a new point of some seriously messed up failure (or even just management, testing, and setup) that you never had before ;)
- fransje26 2y agoNot stopped. The traffic would be rerouted to the opposite lanes. It's obviously safer to have one-directional traffic than bi-directional traffic, so the bridge makes sense. The throughput is also higher.
- Nathanael_M 2y agoDoes anyone know of any good reading material / papers on effective road maintenance and construction? Asphalt quality, longevity, cost, processes, success stories, etc. Cold weather climates would be a bonus.
- boneitis 2y agoNot really what you're asking for, but Sacramento's "Fix 50"[0] project is a currently ongoing development project where I can offer some commentary as a citizen who has no knowledge or expertise in this field. In total honesty, I'm challenged in seeing how there was much in the way of due safety planning performed. In certain framings, accidents and deaths have more-than doubled during construction[1]. The extreme amount of hyperfocus one (and all the other drivers around them) has to exercise in order to cope with the super-confusing lane changes and dodging other drivers not paying attention to the partial repavement lines completely deviating from the actual lanes, and short ramps, (and much worse when driving against the sun) is mind-boggling and renders the local headlines (even if sensationalist) unsurprising.

All of the college students will be gone for the summer and things will be nice and quiet. Then the students return and football season begins. Town becomes a mess. Then the City of Auburn start resurfacing roads or adding medians or additional lanes. It's happened every year for the past 14 years that I've been a resident. It never fails. They always wait until school starts back before they begin any repairs.
