The Senate Environment and Public Works Committee approved a six-year transportation bill that would infuse about $44 billion per year into road and transit projects—enough to maintain current funding levels (adjusted for inflation) through the end of fiscal year 2020. By comparison, President Obama called on lawmakers to spend up to $75 billion per year on infrastructure over a four-year span.

The current transportation bill will expire in September, and the Highway Trust Fund, which pays for the U.S. Department of Transportation’s infrastructure projects, is expected to be depleted as early as August. The proposed reauthorization does not identify a funding source for the bill; that responsibility will fall on the Senate Finance Committee.
