LAWRENCEVILLE -- This weekend, the Georgia Department of Transportation will move drivers out of the way -- again -- for work on the new interchange at Ga. Highways 316 and 20.
If weather permits Saturday, traffic will be moved into temporary lanes built on the outside of the current lanes on Ga. 316. Traffic has already shifted to temporary lanes on Ga. 20 and Collins Hill Road.
"The next phase of construction is to begin lowering State Route 316 where the new SR 20 Bridge will be built. Because SR 316 runs along the highest ridge in the area, 316 must be lowered. This saves us time and money by minimizing the SR 20 bridge structure," said Harold Mull, the department's district construction engineer. "Traffic will be redirected from SR 316's normal path to the outside lanes that will eventually be ramps for the new interchange.
"Please slow down and follow the signs and barrels until you get used to this change," he added. "Remember, all fines are doubled in a work zone if you are ticketed."
To shift to the lanes, crews from GP'S Enterprises Inc. of Auburn are planning lane closures and traffic pacings beginning at 9 p.m. Saturday, so the new lanes will be operating by Sunday morning.
Eventually, the new lanes will be used as ramps for people to access Ga. 20 and Collins Hill Road, instead of the existing intersections.
"This project will build one interchange or exit to allow traffic from State Route 316 to access State Route 20 or to access Collins Hill Road using a system of long ramps," Mull said. "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."
The $37.4 million project is expected to be complete by the end of 2014.
