I think public works are cool. In this instance, one of the complications which add....complications....to these projects is that traffic is crossing the bridge under construction. And in the case of many of diverging diamond bridges, they are nearly always over a freeway and incorporation onramps and offramps. The complications of accommodating two onramps and two offramps in addition to street lanes in both directions make them more...complicated.
It is like repairing a watch while the watch is ticking. If they could just close the bridge, the time investment would probably be cut roughly in half. But they almost never can do this. Simply closing a bridge would raise, not lower, total complications. City and county people would be involved, and would need to buy off. This is unlikely.
