This project involves the addition of 10 miles of newly constructed toll lanes north of the existing I-85 Express lanes. Located entirely within Gwinnett County, these lanes begin north of the existing express lanes on I-85 at Old Peachtree Road and would extend to Hamilton Mill Road. These lanes will be designed to improve traffic flow, increase options for motorists and transit and registered vanpool customers, provide reliable trip times, create jobs and bring economic benefits to the residents of this region. These lanes will be managed by a variable priced tolling system. In addition to the toll lanes, new auxiliary lanes are proposed for construction to keep traffic moving in the congested areas of the corridor. Auxiliary lanes will be constructed between on- and off -ramps to allow drivers a safe way to merge into traffic while also preventing bottlenecks caused by drivers attempting to enter or exit the freeway.
