Alpharetta, Georgia – Construction is beginning on a major stretch of SR 120/Old Milton Parkway in Alpharetta, marking the start of a long-term effort to reshape one of the city’s busiest corridors and ease the traffic pressure that has built there over time.
Georgia DOT contractors are set to begin work this week on the widening and reconstruction project between North Point Parkway and Kimball Bridge Road in Fulton County. The first visible step will not be new pavement, but preparation.
Weather and site conditions permitting, crews will start clearing vegetation along the roadway so utility companies can reach underground and overhead lines that must be moved before the larger roadwork can take shape.
That early phase is expected to involve several utility providers, including Atlanta Gas Light, Comcast and Georgia Power. Once the clearing work is finished, the relocation process will move forward in stages. One company will complete its portion, then another will follow, creating a cascading schedule that gradually opens the way for the roadway expansion itself.
For drivers, that means the project will arrive in pieces before its full impact becomes clear. Lane closures are expected during clearing and utility work, with those restrictions used to protect both motorists and crews working close to traffic. Officials are urging people traveling through the area to slow down, stay alert and watch carefully for workers in the zone.
When completed, the project will significantly alter the corridor. Plans call for two new travel lanes, one in each direction, along with sidewalks, a 20-foot raised median and the replacement of two bridges over Big Creek. The broader goal is straightforward: reduce congestion and cut down on delays along a route that has become increasingly strained by local growth and daily traffic demand.

The scale of the undertaking reflects that challenge. Valued at $30 million, the SR 120 Widening and Reconstruction Project is scheduled for completion in late summer 2029, making it a multi-year investment in both mobility and safety for this part of Alpharetta.
For now, the transformation begins with clearing crews, utility adjustments and the first signs of a road preparing to become something larger. Motorists looking for the latest traffic updates and work-zone conditions can call 511, visit 511ga.org, or use the Georgia 511 app before traveling.
