With the debt deal behind them and the Federal Aviation Administration at least temporarily reopened, members of Congress left on their annual month-long summer recess this week. When they return, only 24 days will remain until September 30, the end of the federal fiscal year when both the latest extension of SAFETEA-LU and most of the federal gas tax are due to expire.

Max Baucus has come up with a way to bridge the $12 billion funding gap between how much is in the Highway Trust Fund and how much the Senate’s two-year reauthorization measure proposes to spend. And state officials are pondering what the debt deal could mean for transportation. Plus, items of note on public-private partnerships, high-speed rail, tolling, motorcycle helmet laws and other issues.
