This section provides an overview of recent federal surface transportation laws. The Fixing America’s Surface Transportation (FAST) Act, enacted in December 2015, authorizes Federal highway, highway safety, transit, and rail programs for five years from Federal fiscal years 2016 through 2020. The FAST Act represents the first long-term comprehensive surface transportation legislation since 2005. The FAST Act authorized $305 billion from both the Highway Trust Fund and the General Fund of the United States Treasury. Its predecessor, the Moving Ahead for Progress in the 21st Century Act (MAP-21), was signed into law on July 6, 2012, and took effect on October 1, 2012. MAP-21 authorized approximately $105 billion in spending for federal highway and public transportation programs for FY2013 and FY2014 combined. It also made major changes to the structure of those federal funding programs.
