From today's radio address: President-elect Barack Obama lays out key parts of Economic Recovery Plan
" ... Second, we will create millions of jobs by making the single largest new investment in our national infrastructure since the creation of the federal highway system in the 1950s. We’ll invest your precious tax dollars in new and smarter ways, and we’ll set a simple rule – use it or lose it. If a state doesn’t act quickly to invest in roads and bridges in their communities, they’ll lose the money."
Oddly this comes after making federal buildings energy efficient, I would think this is a bigger deal, but still it should be a large inflow for maintenance and rehabilitation projects, and hopefully won't be wasted.
