It’s because we already have highways and our car culture is hard to change. Highways were also originally built for national defense with the economic benefits as a secondary force. Defense projects traditionally get tons of funding in the US.
Convincing a generation that witnessed two world wars to back a massive defense project wasn’t difficult.
- ralphie02 7y agoCan you elaborate on the national defense? How is the highway useful with defending the country? Defending from who? I can only think of highways as secondary runways for planes but I'm unsure as to how much that helps your case.
- thrower123 7y agoThe only reason that I-95, for instance, extends as far as it does, is because of the Strategic Air Command bomber base in Limestone, ME. A lot of the other more nonsensical routings of the interstate system make sense when you take into consideration where strategic bases were located in the 50s and 60s.

- steve19 7y agoWars are won with logistics not guns. Getting troops and supplies across the country would be key to defending it from an invasion. The interstate highway system was built in part for military purposes and partly designed by the Army: https://en.m.wikipedia.org/wiki/Interstate_Highway_System https://en.m.wikipedia.org/wiki/Interstate_Highway_System
- ghaff 7y agoEvacuating cities in the event of an atomic attack was also cited as a reason though that obviously seems questionable as well. As I wrote in another comment, the defense justification was probably mostly just a way to get the help get the act passed.
- bobthepanda 7y agoKatrina and Harvey showed that at best, evacuating cities with highways is an extremely long, drawn out process that will most likely leave the most poor and destitute (who don't have cars) totally stranded.
- ghaff 7y agoYes. Basically you can't rapidly evacuate cities. Maybe highways help a bit but, if you can barely handle commuter traffic on a given workday, you're certainly not going to completely and quickly evacuate a city if there's some threat--and that's before you even get to the issue of people who don't own cars. So the idea that highways would be useful if there were an imminent threat of nuclear attack looks pretty silly.
- bobthepanda 7y agoIt depends on how quickly and how far you need people to evacuate. Lower Manhattan on 9/11 was evacuated mostly by foot and sea, with over half a million evacuated by boat alone: https://en.wikipedia.org/wiki/Maritime_response_following_September_11_attacks https://en.wikipedia.org/wiki/Maritime_response_following_Se...
- slededit 7y agoThey don't completely solve the problem, but it would be much harder to evacuate the cities without the highway system in place.
- bobthepanda 7y agoRail has upper capacity in the ranges of 60-90k passengers per hour, whereas car lanes are in the range of 2-3K passengers per hour in free flowing conditions. Granted that 60-90K figure doesn't involve people trying to shove furniture, pets etc. into their vehicles, but you could move quite a lot more with rail.

- ghaff 7y ago>Highways were also originally built for national defense with the economic benefits as a secondary force. That's the standard story. From what I've read though, Eisenhower wanted to build the Interstate Highway System for a number of reasons of which defense was only one--and possibly a fairly minor one. But he knew that playing up the defense angle was a good strategy to get the plan passed.
- Jagat 7y agoRoads were built in the ancient Rome mainly for troops, horses, and chariots to travel with ease for battles and defense. Similar story.
