After holding an open house in February to solicit feedback on proposals to ease congestion at the intersection of Holly Springs Road and Post Oak Tritt Road, Cobb DOT has scheduled a similar public meeting this month.
The next open house is set for Tuesday, May 14, from 6-7:30 p.m. at the Mountain View Regional Library (3330 Sandy Plains Road) “to review community input received on the Holly Springs Corridor 2022 SPLOST project.”
Cobb DOT has presented three options for improvements at that intersection:
- A roundabout costing $3.4 million
- A signal upgrade costing $2.5 million
- Right turn lanes costing $449,000
Another proposal includes a signal improvement at Holly Springs and Sandy Plains Road, at a cost of $383,000.
Those expenses don’t include acquiring right-of-way properties. The available budget overall is $3.9 million.
Cobb DOT said a roundabout would provide the best traffic relief option, in terms of reducing wait times (see table below).
If that’s done, the existing traffic signal would be removed, and a multilane roundabout would be constructed, similar to what’s on Hembree Road at the entrance to Pope High School.
The signal upgrade calls for through lanes going north and south as well as turn lanes in the north-, south- and eastbound lanes, with the signal rebuilt.
Those projects would take an estimated 16 months to complete.
The third option would add southbound and eastbound right lanes and rebuild the signal.
That option, plus the Holly Springs-Sandy Plains option, would take around six months to complete
Cobb DOT didn’t specify what proposed changes may be in store for the upcoming open house, but the project is still considered to be in the conceptual stage.
