Active Construction

GDOT Resurfacing of Rt.120

The Georgia Department of Transportation (GDOT) began resurfacing Rt. 120 (Marietta Highway) the evening of Sunday, April 17th. The work will take approximately four weeks, weather permitting, and will begin in Cobb County and extend to Rt. 9 (Atlanta Street) in Roswell.

The work will be done during overnight hours between 8 p.m. and 5 a.m. Travelers are reminded to use caution when traveling through this area as loose debris is a natural part of the resurfacing process.  

GDOT Resurfacing of Rt.92

The Georgia Department of Transportation (GDOT) began resurfacing Rt. 92 (Crossville Rd.) from the Cobb County Line to Highway 9 (Alpharetta Hwy.) on March 28.

The project involves milling, paving, and restriping the road, as well as replacing traffic detection devices.

The first part of the project is the removal of traffic-detection devices, which will begin March 28. This process will take seven to ten days to complete. Soon after, the actual work related to the paving operations will follow. It is estimated that the paving will take at least two weeks and up to four weeks to complete.

All activities will be carried out in the evening hours from 8:00 p.m. to 5:00 a.m., primarily from Sunday evening through Thursday evening. Some activities could occur on Friday and Saturday evenings, as well.

Travelers are reminded that loose debris is a natural part of any process involving milling and preparation of the road surface and to use caution when traveling through the area.  

Sun Valley Phase 1A Project

This is the first phase of a project to connect the existing Sun Valley Drive with the existing Warsaw Road. The project will grade an existing detention pond and provide two treatment cells within existing City property to enhance water quality and detention for the surrounding area before the water reaches Foe Killer Creek. The project will also construct a double 8’ x 8’ culvert carrying a creek under the proposed Sun Valley Drive connection. This project is under construction and is expected to take up to three months to complete.

Houze Road (SR 140) at Hembree Road Roundabout

This project will construct a multi-lane roundabout at the intersection of Houze Road/SR 140 and Hembree Road. It will also construct a multi-use trail along the south side of Hembree Road for pedestrian and bike mobility connecting to Hembree Park. The project is under construction and is being managed by Georgia DOT.

Current work as of April 2016 is utility relocation. Expect periodic lane closures, mostly during mid-day.

Projects at Holcomb Bridge Road and GA-400


Holcomb Bridge Road Westbound Through Lane and Streetscape

This Bond-funded traffic operational improvement project will add a third westbound travel lane along Holcomb Bridge Road (SR 140) between Old Alabama Road and SR 400 northbound on-ramp. The project consists of turn lane and signal upgrades at the intersections of Old Alabama Road and Market Boulevard, new wide sidewalks, pedestrian lighting, and streetscape enhancements.

Holcomb Bridge Road at SR 400 Northbound Ramp Intersection Improvement

This Georgia DOT-funded traffic operational improvement will eliminate the Holcomb Bridge Road eastbound "trap lane" approaching Old Alabama Road. The project will add a right turn lane to the existing SR 400 northbound ramp (exit 7A), modify the existing traffic signal at the northbound ramp terminus, and extend the westbound left-turn lane to southbound SR 400.

***April 2016 Update on HBR/GA-400 Projects***

The construction is still in progress. The contractor is finishing installation of traffic signal equipment, vehicle detection, and signage. The last major work involves turning on the new traffic signal at the northbound ramp to improve operations. Construction is expected to be completed in April 2016.

Citywide Resurfacing

Resurfacing of selected surface streets will begin in summer 2016. This site will be updated when contractors begin. When resurfacing is underway, please SLOW DOWN in work zones, watch for lane closures and delays, and stay aware! Also, be aware that traffic signal detection equipment is disconnected during resurfacing.
