Construction work planned for 3 bridges on 400, GDOT says

Early construction is set to begin in 2023 and be completed in late 2024. However, GDOT said that schedule is subject to change.

ATLANTA — Georgia's Department of Transportation has released new details about a construction project on SR 400 north of Atlanta.

According to GDOT's website, Phase 1 of the Design-Build project has been advanced from the SR 400 Express Lanes project. Three bridges on Pitts Road, Roberts Drive and Kimball Road will be replaced in order to accommodate future SR 400 express lanes. 

Here's a look at the construction highlights for each project: 

Pitts Road Bridge 

Pitts Road Bridge will be replaced and widened to allow for a 12-foot multiuse path on the south side, a sidewalk on the north side, and interior barrier walls on both sides–  separating pedestrians from the two travel lanes. GDOT said this project is a local agreement with the City of Sandy Springs.

GDOT said there have been approved detours for Pitts Road Bridge and Kimball Bridge Road. Staged construction is anticipated for Roberts Drive Bridge and no detours are currently planned.

Project status 

The project is in the early stages of procurement of a Design-Builder, who will complete the design and construction for the bridges. Early construction is set to begin in 2023 and be completed in late 2024. However, GDOT said that schedule is subject to change. The project has been environmentally cleared under the SR 400 Express Lane project. Noise barriers are also being evaluated for the project in accordance with GDOT's noise policy and the Federal Highway Administration noise regulations.
