I-85 Express Lanes

Welcome to the I-85 Express Lane extension project site. The Georgia Department of Transportation developed the I-85 Express Lane extension project in an effort to provide commuters with a more reliable, free-flow commute option that will complement the state’s multi-modal approach to managing traffic demand. This includes transit and roadway investments in the I-85 corridor that will establish the vision for a future system of Managed Lanes in the Atlanta region.


Project Description

The project involves the addition of one lane in each direction along I-85 in north metro Atlanta from just north of Old Peachtree Road in Gwinnett County to Hamilton Mill Road. The additional lanes will be express lanes. South of I-985, the project proposes to widen I-85 outside of the existing eight-lane mainline. While north of I-985, widening on the inside shoulder along the four-lane I-85 section. Existing travel lanes have a posted speed limit of 65 MPH south of I-985 and 70 MPH on points north along I-85. The project is approximately 10 miles in length and located entirely within Gwinnett County. The purpose of the proposed managed lanes is to create realistic travel time savings through the use of variable priced tolling to manage volume in the lanes and maintain a minimum average speed.
