The reconfigured interchange at Ashford Dunwoody Road and I-285 that's designed to reduce traffic jams is expected to be operational June 4, according to officials with the Perimeter Center Community Improvement Districts. The "diverging diamond" alignment, the first in Georgia, will put cars which would travel 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. You can view a simulation of the I-285 interchange. 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 …

Commuters using the Ashford Dunwoody Road access to I-285 will see a lot of construction during the next two weeks, which could cause some delays. The heavily trafficked interchange is being reconfigured to a "diverging diamond" design that is designed to reduce traffic by 20 percent in the long run. Ramp construction will be going on at the intersection, including concrete work and utility relocation, according to the Georgia Department of Transportation. The good news is no lane closures are expected during this construction phase.

Monday, crews began removing reees along the westbound entrance to 285 at Ashford Dunwoody Road. The tree removal is the first step in a project that will reconfigure the way the bridge over and entrances to 285 at Ashford Dunwoody Road. When construction is complete, which is expected in September, the new road configuration will have drivers shift to the "wrong side of the road" as they approach either side of the bridge. Drivers heading to I-285 will turn directly onto a ramp without having to cross on-coming traffic. Drivers heading straight through the interchange will return to the "right side of the road" after crossing the bridge. The interchange is expected to reduce traffic delays by 15 to 20 percent, according to the Perimeter …

Next week, the Ashford Dunwoody Road Bridge over 285 will begin getting a facelift, bringing a new traffic flow design to the state of Georgia. Construction crews will start in on the state's first diverging diamond interchange. When construction is complete, which is expected in September, the new road configuration will have drivers shift to the "wrong side of the road" as they approach either side of the bridge. Drivers heading to I-285 will turn directly onto a ramp without having to cross on-coming traffic. Drivers heading straight through the interchange will return to the "right side of the road" after crossing the bridge. According to the PCID, the new interchange is expected to reduce traffic delays during evening rush hours up …

Disclaimer - I'm not a city planner or civil engineer. That said, I think a big point that needs to be emphasized is safety. Apparently this creates more "free turns" - which has shown to significantly reduce the number of accidents in studies from diverging diamonds implemented in the Midwest states. I believe the creation of left turns (think coming down AD from Marist to go west on 285) onto … more ›
