The FAST Act is the five-year federal legislation to improve the Nation’s surface transportation infrastructure, including our roads, bridges, transit systems, and rail transportation network. The bill reforms and strengthens transportation programs, refocuses on national priorities, provides long-term certainty and more flexibility for states and local governments, streamlines project approval processes, and maintains a strong commitment to safety. The FAST Act was enacted in December 2015 and replaces the previous federal transportation legislation (The Moving Ahead for Progress in the 21st Century Act (MAP-21), enacted in 2012).
