A multimillion dollar contract has recently been approved to convert the intersection of Routes 316 and 20 to an interchange. Vehicular traffic navigates the intersection Thursday afternoon.
LAWRENCEVILLE -- A contractor has been picked for the $37 million project to clear one of Gwinnett's most congested intersections.
With construction expected to begin in the spring, crews from G.P.'S Enterprises Incorporated of Auburn will work to convert two intersections along Ga. Highway 316 to interchanges.
The project will create limited access along the highway at Ga. 20 and Collins Hill Road, near Georgia Gwinnett College. It is expected to improve safety and ease congestion.
"This project will build one interchange or exit to allow traffic from 316 to access 20 or to access Collins Hill Road using a system of long ramps, called collector distributor lanes," Todd McDuffie, district engineer of the Georgia Department of Transportation. "The existing signalized intersections at State Route 20 and at Collins Hill Road will be removed as the interchange is finished. It is similar to the system we have along I-85 from SR 120 down to Pleasant Hill Road. You get off the mainline of I-85 south at SR 120 and use the parallel roads to access the exit you need."
After months of reviewing bids for the project, the Auburn company was selected Thursday for the work, which will add 2.237 miles of new roadway and two new bridges over Ga. 316.
Construction is expected to begin in the spring and is scheduled to conclude by the end of 2014. Updates on lane closures and traffic impacts will be released later.
