Sandy Springs motorists may experience a little frusration, this weekend, before ultimate relief. Perimeter's highest-trafficked intersection at Ashford Dunwoody Road and I-285 will be closed for the weekend.
Technically, the intersection closes after the commute Friday - at 9 p.m. through at 5 a.m., Monday.
The bridge will be closed and people who want to go northbound or southbound on Ashford Dunwoody Road will need to detour around using the Perimeter Center Parkway Bridge, according to a statement by the Perimeter Community Improvement Districts.
In addition, 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.

The Ashford Dunwoody Bridge serves nearly 55,000 vehicles per day, the statement said.
Construction during the weekend closure will include removal of asphalt, construction of a pedestrian walkway, paving, restriping and installation of traffic signals.
The "diverging diamond" alignment, the first in Georgia, will put cars that are traveling in the right hand lanes into the left lanes of traffic while in the interchange, allowing them to make left turns unimpeded onto I-285.
The loop ramp used to access I-285 east from the interchange will be removed. The eastbound ramp is a major contributor to the congestion in the interchange, according to transportation officials.
The new alignment is designed to reduce traffic during peak hours up to 20 percent and increase safety. Once the new alignment is opened, construction at the interchange will continue, according to Georgia Department of Transportation engineers.
