ATLANTA - Georgia Department of Transportation (GDOT) contractors have extended the bridge rehabilitation activities on Post Road Bridge over I-20 in Douglas County through mid- August.

The bridge maintenance work requires the closure of the bridge to through traffic and those closures were put in place on June 17. The tentative completion date for the project was July 31; however, additional utility work is needed. Once the remaining utility work is completed, the contractor estimates that the bridge rehabilitation will be complete August 19.

Message boards are in place to give drivers advance notice of the detour and to direct drivers to the detour route as follows.

To access destinations north of Post Road Bridge/SR 78 from south of I-20 and the bridge:

  • Take Mason Creek Road eastbound;
  • Turn left onto Cowan Mill Road eastbound;
  • Turn left turn onto Bright Star Road northbound;
  • Turn left turn onto SR 78 westbound; and
  • Turn left or right to access Post Road/Mann Road.

To access destinations south of Post Road Bridge from north of I-20 and SR 78:

  • Take SR 78 eastbound;
  • Turn right onto Bright Star Road southbound;
  • Turn right onto Cowan Mill Road westbound;
  • Turn right onto Mason Creek Road westbound; and
  • Turn left onto Post Road southbound.

The work on Post Road is part of a bridge rehabilitation effort of six bridges in Douglas County where they cross over I-20: Tyson Road over I-20 eastbound, Tyson Road over I-20 westbound, Post Road over I-20, Liberty Road over I-20, Burnt Hickory Road over I-20, and North County Line Road over I-20.

Rehabilitation includes raising the structures' vertical clearance, bridge deck preservation (with polymer overlay), painting of steel beams, joint replacement where necessary and stabilizing the superstructures and substructures. Construction on each bridge will require 30-45 day detours for each bridge to ensure safety for workers and drivers.

Motorists are cautioned to reduce their speed while traveling through work zones, pay attention and watch for workers. Before heading out, get real-time information on work status and traffic conditions. Call 511, visit, or download the Georgia 511 app.
