Delays expected on 316 today due to 'controlled blasting'

LAWRENCEVILLE -- Georgia DOT has announced a controlled blast at 1 p.m. today to remove rock from State Route 316 at the State Route 20 intersection. Traffic will be stopped briefly on the highways before the blast occurs, officials said.

"Controlled blasts are the most efficient method of removing large rock deposits from a work area. This rock is in the area of the new SR 20 bridge over SR 316. To ensure safety of motorists, traffic will be stopped approximately 1,000 feet away from the intersection on all four approaches for about 4-5 minutes," said District Construction Engineer Harold Mull.

Once the project is completed, motorists on 316 can access 20 and Collins Hill Road via ramps instead of the existing intersections and vice versa.

"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. 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," Mull said.

This $37.4 million construction project includes 2.23 miles of new roadway and two new bridges over 316. The project completion date is Dec. 31, 2014 ,and the contractor is GP'S Enterprises, Inc. of Auburn.
