The I-285 Top End Express Lanes is one of the Major Mobility Investment Program (MMIP) projects to improve mobility along the northern segment of I-285 in metro Atlanta, one of the most heavily-traveled and congested interstate highways in America. The project will be part of the larger Georgia Express Lanes network, designed to provide a connected transportation system with reliable trip times for motorists.

Through the development of the MMIP, we have considered industry feedback regarding the quantity and timing of major procurements, as well as the size of the procurement packages. After assessing the state of the program, the I-285 Top End Express Lanes project will be constructed into two smaller packages to maximize competition, maintain good pricing, and phase construction for improved maintenance of traffic during construction. The projects will cover the same areas of I-285 and SR 400; however, will be constructed separately as the I-285 West Metro Express Lanes and I-285 East Metro Express Lanes.

I-285 Top End West Express Lanes: The project focuses on adding two new at-grade and elevated, barrier-separated express lanes in both directions of I-285 between Paces Ferry Road and SR 400.

I-285 Top End East Express Lanes: The project focuses on adding two new at-grade and elevated, barrier-separated express lanes in both directions of I-285 between Henderson Road and SR 400, and north on SR 400 from Johnson Ferry Road to the North Springs MARTA Station.

The projects are in early stages of development, so the initial concept design is underway and access points are still being determined. The project team is coordinating and collaborating with our partners, such as DeKalb and Fulton counties, the Top End Mayors, and the ATL on future transit and transportation endeavors.
