Major Perimeter Market Projects

The Transform 285/400 improvement project is designed to help reduce traffic congestion and enhance safety in the area near the I-285/SR 400 interchange in metro Atlanta. This priority project adds new flyover ramps, new collector-distributor lanes and other facilities to aid east-west travel along I-285 and north-south travel along SR 400. The project will improve 4.3 miles of I-285 from west of Roswell Road to east of Ashford Dunwoody Road and 6.2 miles along SR 400 from the Glenridge Connector to Spalding Drive.

I-285 Top End Express Lanes

In our ongoing efforts to deliver the best and most impactful versions of much-needed infrastructure projects to Georgia, Georgia DOT is revising the Public-Private Partnership (P3) delivery model for the I-285 Top End Express Lanes. This revision would provide significant benefits to Georgia taxpayers, users of the I-285 Express Lanes system, local communities and all travelers in the I-285 corridor north of either interchange at I-20 on the east and west sides of the metro Atlanta area by delivering better projects requiring less public funding.

The I-285/I-20 West Interchange project calls for improvements of the interchange and addition of lanes along I-20 in Cobb, Douglas, and Fulton counties. Additional work includes construction of collector-distributor (CD) lanes and the modification or replacements of bridges along I-20. This project, once completed, will provide more efficient traffic flow through the interchange.

Current / On-Going Projects

Bicycle Implementation Strategy

The Bicycle Implementation Strategy identifies steps to be taken by Perimeter CIDs, its members, local municipalities, and other private and public partners to continue the transformation of Perimeter into an urban center.

Traffic Officers

Off-duty DeKalb County, Dunwoody, Sandy Springs and Fulton County officers direct traffic at up to twenty one (21)  (Sandy Springs, Dunwoody, Brookhaven) intersections in the Perimeter Business District during high-peak traffic times to help motorists travel safely and with ease.

Lake Hearn at Peachtree Dunwoody

In 2012 PCIDs was awarded $1M from the GTIB/SRTA in grant funding to advance a concept plan for the Lake Hearn @ Peachtree Dunwoody Road Intersection in partnership with City of Sandy Springs.

Commuter Trails

PCIDs has been awarded funding is to design commuter trails between corporate campuses in the Perimeter community.

Mast Arm Decorative Bases

Recently, PCIDs has replaced the bases of many of the mast arms in the district with newer, more decorative bases featuring our logo.

Past Accomplishments

Ashford Dunwoody DDI

The Diverging Diamond Interchange (DDI) design shifts the flow of traffic to the opposite side of the road, reduces points of traffic conflict,  and improves traffic flow and safety.

Flyover Bridge

This 1,100-foot multi-modal bridge has innovative design features such as 4-foot wide bicycle lanes and 6-foot wide pedestrian lanes. HOV access to MARTA is on the horizon.

Hammond Half Diamond

The half-diamond interchange—named for how it looks from above as it connects the two roads—provides an exit off of Ga. 400 and reduces traffic congestion.

Hammond Drive Mid-Block Crossing

PCIDs installed new crosswalks on Hammond Drive with clearer striping and brighter paint to improve sense of place in the area and keep pedestrians safe.
