They're talking about the middle of next month, at the earliest - and that would require another extension of the current law, which is set to expire on April 1. This is a massive package that includes all sorts of highway projects, as well as a federal loan program that could facilitate the subway extension to Westwood and other local transit projects. The Senate has signed off on its own version. From Politico:
The guts of the bill would stay the same as the latest version that hasn't gone anywhere -- transit would continue to receive a dedicated share of the federal gas tax, an issue that had drawn opposition from a number of Republicans in suburban districts, according to a source who attended the meeting. The general game plan over the next few weeks, as laid out by aides: continue rallying and gauging support for a five-year bill when members return to town next week. An extension of the current law, slated to expire April 1, would hit the floor sometime during the March 26 week.
