Road Work Ahead: 'Significant Delays' Expected On State Route 120

MARIETTA, GA — Significant traffic delays are expected along Dallas Highway/Whitlock Avenue near Marietta High School this week as crews work on the area's trail segment of the Kennesaw Mountain Pedestrian Improvements project, the Cobb County Department of Transportation announced Monday.

Delays are mostly expected along the corridor between John Ward Road and Cheatham Hill Drive, with the worst of the delays in the afternoon in the westbound direction, according to the Cobb DOT.

Crews are working in that area from 9 a.m. to 4 p.m. on weekdays, and road capacity is reduced to one lane during that time. Alternate routes are recommended.

The approximate $14.5 million Kennesaw Mountain Pedestrian Improvements project calls for improvements along Dallas Highway/Whitlock Avenue, as well as Cheatham Hill and Burnt Hickory roads, to construct three multi-use trails that would be separated from the roadway by a grassed strip, curb and gutter, according to a fact sheet from the Cobb DOT.

Work is already occurring on the following roads for this project, funded by the voter-approved 2016 Special Purpose Local Option Sales Tax fund:

• Cheatham Hill Road between Powder Springs and John Ward roads.
• Dallas Highway/State Route 120/Whitlock Avenue from John Ward Road to the National Park Services access drive to the Illinois Monument.
• Burnt Hickory Road from Whitlock Avenue/SR 120 to the NPS parking lot across from Old Mountain Road.

The work on Whitlock Avenue/Dallas Highway should be completed roughly a year from now, Cobb DOT Program Pre-Construction Manager James Hudgins told Patch on Tuesday.

Completion on all three segments is expected in June 2023. The project is a collaborative effort by Cobb County, the city of Marietta, the National Park Services, Georgia Department of Transportation and the Federal Highway Administration.
