This just in: House Republicans introduced a three-month extension to avoid a shutdown of transportation programs after March 31.
From the House Committee on Transportation and Infrastructure:
"In order to ensure continuity of current surface transportation programs while the Transportation and Infrastructure Committee and House Republicans continue to work toward a responsible transportation bill that provides long-term certainty, reduces the size of government, eliminates earmarks, and is fully paid for, Chairman Mica, Chairman Duncan and Chairman Camp introduced a three-month extension of transportation programs today. This legislation, the Surface Transportation Extension Act of 2012 (H.R. 4239), will extend current programs through June 30, 2012."
