Major Mobility Investment Program

Georgia DOT is advancing the Major Mobility Investment Program across the state in an effort to yield a significant reduction in congestion along key freight and passenger corridors. Once the projects are completed, they will lead to a 5% reduction in delay and travel time savings in the year 2030, as compared to doing nothing and allowing traffic congestion to increase.

 Announcements

 Projects

The initial 11 mobility projects rely on state and federal funding dedicated by law to improving roads and bridges. Together, they will add more than 316 new lane miles in Georgia’s metro areas. The projects also will create additional capacity; improve the movement of freight; provide operational improvements and efficiencies; enhance safety; and decrease travel times.
