Moving Ahead for Progress in the 21st Century Act

The Moving Ahead for Progress in the 21st Century Act (MAP-21), enacted in 2012, is a law that funds transportation projects across the U.S., including roads, bridges, and transit systems. Its goal is to improve infrastructure, enhance safety, and promote economic growth by allocating federal funds more efficiently. The law emphasizes performance-based planning, meaning transportation agencies use data to prioritize projects that best meet safety, mobility, and infrastructure needs. Overall, MAP-21 aims to modernize transportation networks, reduce congestion, and support sustainable, long-term infrastructure development.
