It has nothing to do with car dependency. Just like every other public project in the USA, if it isn’t immediately broken, then they just “defer maintenance” and allocate that spending to somewhere else. I like nice art statues. I like a bridge that doesn’t collapse more. If you can’t afford to maintain and fix a bridge, you can’t afford your budget. Either increase taxes or decrease spending. But deferring these costs and stealing from the coffers because it won’t be your problem later should be criminal.
