While the Pleasant Hill Road at I-85 Diverging Diamond Interchange (DDI) continues to function efficiently today, as traffic continues to grow on Pleasant Hill Road, traffic levels will begin to exceed the DDI’s capacity. Later this decade, the DDI’s operation will have an unacceptable level of service. Efforts are beginning to visualize the future of Pleasant Hill Road and the interchange with I-85.
The Gwinnett Place CID has prepared conceptual layouts, traffic analysis, potential right-of-way impacts and cost estimates for a series of improvements around Pleasant Hill Road and I-85. In partnership with the Gwinnett County Department of Transportation, the I-85 at Pleasant Hill Road Interchange Modification Report (IMR) has been completed and submitted to the Georgia Department of Transportation and the Federal Highway Administration.
An interim project is being considered to add triple right-turn lanes at the south bound off- ramp with signal modifications. The project concept has been finalized and a notice to proceed has been issued for the design of the southbound exit ramp widening.
