Not if there is already a bridge there that is meeting demand.
Many of these type projects replace an ugly old concrete overpass with a fancy one with fancy lights and architectural details - none of which add any financial returns. That is exactly what they did here in California.
Or a train to nowhere...
Fair enough, last first as is my wont though. Really we do not differ much on this.. if at all.
So last first. Trains to nowhere don't cost much in the grand scheme of things. At most 1%. If that lubricates the
wheels.... meh.
Onto the second. Pretty/interesting is good, cast concrete ... such does not cost much.
Last...if it is working.. probably will not be replaced.
