What's more expensive and has long term track record success?
- Turing_Machine 9y agoWell, given that both tunnels and elevated roads are still being built, the most expensive likely varies depending on the situation. If Musk really reduces the cost of tunneling by 10x, that calculus will shift in the direction of tunneling, obviously. Dirt roads are extremely cheap and have been around forever. That doesn't make them the best choice in a modern society.
- jhall1468 9y agoElevated roads require surface space. A tunnel requires a small entry-point.
- CodeWriter23 9y agoPay today or pay tomorrow. I don't think it is an outlandish thought IF $100M/mile tunnels are achieved that the TCO for an elevated roadway will be higher. Elevated roadways have to be replaced eventually. Tunnels are more durable, look at the Holland Tunnel for example, 89 years old and no need for replacement in sight. And it's $48M price tag would be $3.3B today for 1.62 miles.
