Why tunnels instead of the Japanese/German solution of ramps/viaducts?
In the same vein, why underground instead of light rail?
See, open air systems like those are much easier to service. Removing a crashed car from that requires just a big crane.
- ianai 6y agoUnderground doesn’t get affected by weather. I wonder whether simply having more tunnels side by side would help for servicing issues. Small, numerous tunnels instead of large tunnels.
- AstralStorm 6y agoBuilding wide tunnels is very hard and nullifies the main advantage of having the tunnel in the first place, which is easier routing. Cost also vastly increases, likelihood of total failure as well. Big tunnels need big supports and big service ducts.
- kanox 6y agoBecause tunnels can go under buildings, roads and other tunnels with very little interference.
- animal_spirits 6y agoBridges can also go above bridges, probably cheaper and safer as well
