Officials Lay Out Weekend Road Closures in Perimeter Area

Sandy Springs shoppers to Perimeter area will experience detours for the Ashford Dunwoody Road bridge. Also, only one lane will be open from Perimeter Center West down to Hammond Drive.

 

Only ramps that provide access to and from I-285 will be open during the closure of the Ashford Dunwooody Road bridge, this weekend. South and northbound traffic will be detoured through the I-285 Perimeter Center Parkway bridge.

Pedestrian traffic will not be allowed on the Ashford Dunwoody Road bridge during the month of June while a pedestrian walkway in the bridge median is completed. The walkway is being placed inside a concrete barrier-protected pedestrian only zone.

This weekend, only one lane will be open from Perimeter Center West down to Hammond Drive.

When traveling southbound on Ashford Dunwoody Road, the detour starts at Hammond Drive. However, the existing ramps from Ashford Dunwoody Road will be open for people to get onto I-285 westbound or I-285 eastbound.

  • If you’re traveling southbound on Ashford Dunwoody Road to destinations south of I-285, the detour will take you right onto Hammond Drive.
  • If you’re traveling northbound on Ashford Dunwoody Road to destinations north of I-285, the detour will take you left onto Perimeter Summit Parkway.

Plans could change if storms hit the area.

“The contractor will be able to proceed with the weekend work as long as the weather cooperates, but based on the current forecast, we expect to close the bridge,” said Lee Upkins, Georgia Department of Transportation district construction engineer, in a statement from the Perimeter Community Improvement Districts.

When the bridge reopens June 4, it will feature a new Diverging Diamond Interchange design and better traffic flow.

“Even though there is more work to be done on the project, I believe that motorists will begin to see an improvement in congestion once they get through the learning curve of navigating the new DDI,” said GDOT Commissioner Keith Golden, in the statement.

Nearly 55,000 cars travel the Ashford Dunwoody Road bridge daily. The PCIDs initiated the project. GDOT is funding the $4.6 million construction cost.

Construction during the weekend closure will include removal of asphalt, construction of a pedestrian walkway, paving, restriping and installation of traffic signals.

When the crossover opens, traffic on Ashford Dunwoody Road will cross from the right side of the roadway to the left side at a ramp intersection signal so vehicles may make free left turns onto the I-285 freeway on-ramp. Traffic will then cross back to the right side of the road at a second ramp intersection. A loop ramp used to access I-285 East from the interchange bridge that has been a major contributor to the congestion in the corridor will be removed.
