The Georgia Department of Transportation had decided to move forward on a project that would create commercial vehicle only lanes on Interstate 75 between McDonough and Macon, according to a report in the Macon Telegraph.

The project would add two non-tolled northbound commercial vehicle lanes to a 40-mile stretch of Interstate 75, starting from Interstate 475 in Macon, Ga. The commercial vehicle only lanes would be the first in the nation and the project cost is estimated at $1.8 billion. The lanes would be limited to commercial trucks and other large vehicles carrying goods.

Construction is set to begin in 2025 with completion estimated in 2029. The new lanes would reduce commercial vehicle volumes in the general purpose lanes in order to improve trip times and safety for motorists. The Georgia DOT expects the lanes to reduce delay on Interstate 75 by 40% in 2030, based on a study conducted by Cambridge Systematics in 2016.

The project is part of the Georgia DOT’s Major Mobility Program that includes 11 projects aimed at improving mobility and safety, fueling economic growth, and improving quality of life for Georgians.
