The MAP-21 Act, signed into law in July 2012, provides approximately $105 billion for highways, safety, and transit over fiscal years 2013 and 2014, while implementing several policy reforms, including the establishment of performance standards and streamlining project delivery processes. It addresses challenges such as funding sustainability, lack of earmarks, and a new national freight policy, while authorizing expanded interstate tolling and modifying existing grant programs. The Act is set to expire on September 30, 2014, prompting discussions about future reauthorization and necessary reforms.
