But also sobering: >San Francisco proposed a new bus lane on Van Ness in 2001. Its opening was recently delayed to 2021, yielding a project duration of around 7,300 days. “The project has been delayed due to an increase of wet weather since the project started,” said Paul Rose, a San Francisco Municipal Transportation Agency spokesperson. The project will cost $310 million, i.e. $100,000 per meter. The Alaska Highway, mentioned above, constructed across remote tundra, cost $793 per meter in 2019 dollars.

> The Alaska Highway, mentioned above, constructed across remote tundra, cost $793 per meter in 2019 dollars. 'the "highway" was not usable by general vehicles until 1943. Even then there were many steep grades, a poor surface, switchbacks to gain and descend hills ...' (https://en.wikipedia.org/wiki/Alaska_Highway#Construction https://en.wikipedia.org/wiki/Alaska_Highway#Construction) plus bridges which were temporary, impassable sections in 1943 when stuff started to melt, etc, etc ,etc. A war-time dirt-road constructed by the army and only traversable by stuff that could probably go off-road anyway is not really the same as building something in an existing city which has to support regular bus traffic.

Yes, that's bad. Do keep in mind, though, that in quite a few places the Alaska Highway was just tundra. It was built in wartime (WW2) to get a land supply route to bases in Alaska as fast as possible. The intended use case was a convoy of military trucks with a engineers and repair gear who could fix the road as they travelled along it. Impressive, but different from a modern highway.

Didn’t check the link to see if it’s listed, but another one would be the Second Ave “T” subway line in NYC. Originally started in ~1931, now it’s finally got a few sections built (part of the “Q” line now).
