Tilly Mill Road at North Peachtree Road

The intersection at Tilly Mill Road and North Peachtree Road was the first intersection improvement to be designed and constructed as a result of the city’s Comprehensive Transportation Plan.  It was determined to be a high priority based on community input and the existing poor level of service. 

This intersection and surrounding area manages traffic from five arterial and collector roads of Dunwoody, providing access to and from neighborhoods and destinations such as Georgia Perimeter College and several area public schools.  As a result of these high volumes and known traffic patterns, the intersection of North Peachtree with Peeler Road was also incorporated into this project with the addition of a traffic signal which was synchronized with the existing signal at Tilly Mill and North Peachtree.  The improvements to this intersection are helping to reduce the average wait time experienced at these duel intersections.

Key project elements such as new sidewalks and bike lanes, additional turn lanes, and pedestrian refuge islands all help to improve the safety and flow of these two related intersections.  Aesthetically pleasing traffic signal mast arms replaced strung signal heads, enhancing the character of this area of Dunwoody. 

The construction scope also included improvements to existing stormwater infrastructure such as pipes and detention facilities to improve downstream conditions.  Relocation of existing utility infrastructure, including the replacement of DeKalb County's water main through this intersection was also incorporated into this construction.  These activities required some tree removal outside of the construction limits outside of the roadway improvements and the city has replaced all of the trees per its No Net Loss of Trees policy.
