Flyover Ramp Opening Next Week
The Transform 285/400 project team will open the new SR 400 southbound to I-285 eastbound flyover ramp early next week, replacing the existing loop ramp at the interchange.
Motorists will travel on the 80-foot-tall ramp until it merges with I-285 eastbound just
before the Perimeter Center Parkway overpass. Signage will direct motorists through the new roadway and ramp configuration. The new flyover ramp is a major permanent alignment to open to traffic.
Motorists on SR 400 southbound to I-285 eastbound will merge to the farthest right lane on SR 400 southbound and merge onto the ramp just before the Hammond Drive overpass. (The ramp is colored green in the illustration below for reference).

Later in the year, crews will also open the SR 400 southbound to I-285 westbound ramp. When this ramp opens motorists will merge onto the second to farthest right lane to access the SR 400 southbound to I-285 eastbound ramp.
See illustrations of the new ramps below.
Upcoming work activities:
Bridge 25 Opening
SR 400 southbound to I-285 westbound new alignment
This fall motorists will start driving on new bridges that make up the Transform 285/400 project. Crews will open to traffic the Ashford Dunwoody Road to I-285 westbound ramp. Motorists will access the Ashford Dunwoody ramp to I-285 westbound the ramp will merge from two lanes into one lane onto the new bridge. The new bridge alignment will merge into I-285 westbound.
The Transform 285/400 project team will also open the new SR 400 southbound to I-285 westbound ramp
(the ramp is colored green in the illustration below for reference). Motorists will need to make a new lane decision earlier on SR 400 southbound to access the I-285 westbound by taking the farthest right lane just before Hammond Drive to access I-285 westbound. Motorists will merge with I-285 westbound just before Glenridge Drive. Motorists should pay close attention to the new roadway configurations. Signage will help motorists navigate the roadway and ramp configuration.
What’s Happening At: 
Abernathy Road
Many changes have occurred over the last few months at the SR 400/Abernathy Road Interchange. The project team permanently closed and relocated the SR 400 northbound exit to Abernathy Road westbound (Exit 5B) in June 2020. Motorists now access Abernathy Road westbound and eastbound by using the same exit, Exit 5. New traffic signals allow motorists to turn left to Abernathy westbound.
In July, the team successfully completed a demolition of a bridge over Abernathy Road at SR 400 northbound. This demolition allowed for the work of drilled shafts, which will help with the construction of the new northbound collector-distributor (CD) lanes. In August, beams were set over Abernathy Road to facilitate the construction of new southbound CD lanes. The team is also planning on opening a new exit ramp which will take motorists from SR 400 southbound to Abernathy Road in fall of 2020.

This month, we shine the employee spotlight on Annalysce Baker, the Public Relations Manager for North Perimeter Contractors, LLC – the Developer for the Transform 285/400 project. Annalysce, a Sandy Springs resident, graduated from University of West Georgia with a degree in Mass Communications. Prior to joining the Transform 285/400 project, she worked for Georgia Department of Transportation, the Georgia Department of Veterans Services, as well as the Fulton County Government.

Annalysce and her team are responsible for all external communications on the Transform 285/400 project. This includes reporting traffic lane closures, newsletters, organizing stakeholder and community meetings, responding to public inquiries about the project, and many other tasks. 

Annalysce says the team’s best work is ahead of them. “Though we have done great things, I think our best accomplishments are ahead of us as we work to communicate to the public and stakeholders about the new bridges and alignments opening to the traveling public,” she said. 

She is also proud of the great relationships cultivated with the local hospitals and the Perimeter Community Improvement District. “The best part about working on the team is the people.”
