ARC Approves 2050 Metropolitan Transportation Plan

On February 14th, 2024, the Atlanta Regional Commission approved a $168 billion Metropolitan Transportation Plan (MTP) to fund transportation projects through 2050.

This plan was released in conjunction with the ARC’s new population forecast for 2050, which projects a 1.8 million resident increase for the 21-county region.


  • $10 billion transit expansion for MARTA bus rapid transit (BRT) in the southern metro area, arterial rapid transit between select MARTA stations in DeKalb County, and the Atlanta Streetcar extension to the BeltLine and Ponce City Market.
  • $13.8 billion as a part of GDOT’s Major Mobility Improvement program. These projects include the managed express lanes around the top half of I-285, interchange reconstruction at I-285 and I-20, and new interchanges on I-85 and I-20.
  • $8.1 billion to add nearly 600 lane-miles of capacity to the region’s arterial network by 2050. This means the widening of major roads like Piedmont Road, Tara Boulevard, Panola Road, Sugarloaf Parkway, and South Barrett Parkway.
  • $105.5 billion is earmarked to maintain, modernize, and operate transportation infrastructure that’s already in place.
  • $3.9 billion towards bike-ped projects on the BeltLine, PATH 400, the Chattahoochee River trails, and others.
  • $5.8 billion dedicated to programs that reduce congestion by encouraging alternative ways of getting around the region, like Georgia Commute Options.

Before moving forwards, the MTP must be approved by USDOT, which could up to 30 days.
