Airport construction grants and other Federal Aviation Administration programs can continue for two more months, thanks to yet another stopgap authorization measure.

President Obama signed the bill into law on Aug. 1.

It is the 15th FAA extension since September 2007, when the last multiyear aviation bill expired. The new stopgap runs through Sept. 30.

The Senate and House have approved different long-term FAA bills. Lawmakers and staff have been negotiating to reconcile the two measures, but were unable to reach agreement by the end of July, when the previous stopgap lapsed.
