Drivers on Holcomb Bridge Road/S.R. 140 at the GA-400 interchange will notice two big changes next week.

On Tuesday, Oct. 20, lane shifts on eastbound Holcomb Bridge Road to accommodate construction on the center median and a new traffic light where eastbound Holcomb Bridge Road meets the top of the northbound GA-400 7A exit ramp will be implemented, the city of Roswell said.

The city’s contractor will complete the work to shift lanes and activate the new traffic light starting after 9 p.m. Monday, Oct. 19. The new traffic signal will be operational by Tuesday morning. The work to rebuild the center median on Holcomb Bridge Road will continue for about four weeks.

During construction, motorists may experience heavy congestion -- especially during peak hours -- and can expect delays, Roswell said.

The new standard stop-and-go traffic signal will be a big change for both eastbound drivers on Holcomb Bridge Road and for drivers coming off the 7A exit ramp from GA-400:

• Eastbound HBR drivers have been used to flowing past traffic merging off the 7A exit ramp without stopping, guided by overhead green arrows. Now, the new signal will stop and start traffic in coordination with traffic coming up the exit ramp.
• Drivers coming up the 7A exit ramp off GA-400 will see that there is no longer a free-flow right-turn lane. Instead, the standard stop-and-go signal will control the flow of traffic onto eastbound Holcomb Bridge Road. In addition, the exit ramp will temporarily operate as one lane while the contractor finishes constructing a second right-turn lane.

These projects are integral to the major transportation improvements the city of Roswell has been making along Holcomb Bridge Road at the S.R. 400 interchange.

The installation of the standard stop-and-go traffic light and the creation of two right-turn lanes on the GA-400 northbound exit ramp 7A will reduce vehicles needing to change lanes as they head east on Holcomb Bridge Road and improve traffic flow and safety.

These projects also aim to eliminate the Holcomb Bridge Road eastbound left-turn “trap lane” approaching Old Alabama Road. The “trap lane” is an apparent through-lane that leads to a turn only situation. This creates weaving in and out of lanes and is a source of accidents in the area. All work at the Holcomb Bridge Road/GA-400 interchange is expected to be complete in early 2016.

Construction activities that require lane closures will occur at off-peak hours, and on nights and weekends. Access through the area will be maintained, and businesses will remain open.

As this is a heavily traveled area even during off-peak hours, drivers may experience delays. Travelers are encouraged to take alternate routes to avoid construction delays.
