The federal government currently budgets about $50 billion a year for transportation, a figure the proposed bill seeks to boost. The increase is causing some lawmakers to delay the bill over questions about how the money will be raised.
"The transportation bill would channel $450 billion in funds to states over six years to upgrade roads, bridges and transit systems. The total would include $70 billion each year to spend on highway and mass transit systems.
'It's extraordinarily unlikely' the bill would pass before October, said Rep. Earl Blumenauer (D., Ore.), a leading proponent of the measure."
