The Surface Transportation Authorization Act, draws both fanfare and trepidation and is widely considered a turning point in American transportation.

The bulk of the bill is dedicated to maintenance rather than highway expansion and construction. Fully $100 billion was set aside for building and expanding mass transit. Another $50 billion is allocated for high-speed rail, dwarfing the $8 billion included in the stimulus package. The bill gives local authorities greater say in how their federal transportation dollars are spent. And our transportation policy would be legally tied to climate protection. The total tab comes to at least $450 billion, twice that of Safetea.

Unfortunately, nobody has quite figured where that money will come from.
