Is the economy leading to a change in land use? Eh. I'd like for it to happen, but the allocation of more money for highways in the stimulus bill leads us in a different direction that I'd like to think we're going. The major evidence will come in a few years after the transportation bill is finalized and money starts moving to projects other than roads. Perhaps we will see that acceleration they're talking about then.
By the way, if you want to see where Interstate bridges are going to crash in your congressional district, DOT has maps.
