Construction to add a diverging diamond interchange (DDI) to Wade Green Road over Interstate 75 in Kennesaw will begin this summer, as early as mid-June. The project will include rehabilitation of the Wade Green bridge and is anticipated to last at least five months. Single-lane and full closures are expected in late September.

Little Willeo Road between Willow Point Parkway and Odins Way in Marietta is now closed to through traffic until July 28, 2017. This project consists of a complete bridge replacement on Little Willeo Road over Timber Ridge Branch as well as construction of two travel lanes, shoulders and pedestrian accommodations.

Motorists should plan to detour and travel carefully in the area.

Beginning May 30, 2017, Keheley Drive from Kemp Road to Keheley Road in Marietta will close to through traffic until June 25, 2017, due to drainage construction work. The existing reinforced concrete pipe has failed, causing settlement between the roadway and sidewalk. During this project, new drainage structures will be constructed, and the 24-inch pipe under Keheley Drive as well as the failure areas of sidewalk and curbing will be replaced.

Motorists should plan to detour and travel carefully in the area.

Construction for the Pope High School roundabout will require the closure of Hembree Road to vehicular and pedestrian through traffic beginning at 6 p.m. May 24, 2017. The closure will be in place for nearly two months, through July 17. Work hours will likely extend into evenings and weekends, starting the first night of closure.

Davis Road from Sandy Plains Road to Holly Springs Road closed May 3, 2017, and will remained closed through July 17, 2017, for safety and operational improvements. In conjunction with the Cobb County School District’s relocation of Mountain View Elementary School, CCDOT will add new right-turn and left-turn lanes on Sandy Plains Road, rebuild a traffic signal at the intersection, add flashing school zone beacons and upgrade the median.

Cobb County DOT is working in partnership with the Cumberland Community Improvement District and other organizations on a number of projects to improve Cumberland area roadways. Learn more about each project below.

The Cobb County Police Department, in collaboration with the Cobb County Department of Transportation and other partners, has developed this traffic management plan (TMP) for events at SunTrust Park, with the following guiding principles:

  • Provide for safe, efficient vehicular and pedestrian arrival and departure;
  • Minimize traffic impacts to nearby neighborhoods, businesses and daily commuters;
  • Leverage extensive thoroughfare network which provides 14 points of access, including two interstates; and
  • Leverage the County's Advanced Transportation Management System (ATMS).

Update (7/17/17): Closure of the bridge for up to four months is anticipated to begin Aug. 7, 2017.

Metal support boxes will be constructed inside the landmark Concord Road covered bridge near Smyrna as part of a scheduled safety project that will close the iconic structure in summer 2017.  

The popular Cobb County-owned bridge is one of the busiest one-lane covered bridges in the South, carrying 7,000 to 10,000 motorists daily. Slated renovations will strengthen it and keep it from leaning.

“The bridge is hit about once a month,” said Jim Wilgus, director of the Cobb County Department of Transportation (CCDOT). “The hits have caused it to lean, and we need to fix that.”

The Cobb County Department of Transportation (CCDOT) debuted “Pete’s Street Smarts,” an educational video on pedestrian safety for children, early this week. A collaboration between CCDOT, the Cobb County Safety Village, Safe Kids Cobb County and Cobb & Douglas Public Health, the animated short showcases what to do—and what not to do—when crossing roads.

Four key tips for traveling safely while walking are illustrated in the three-minute video, including avoiding distractions from devices and waiting to cross at intersections with the protection of the “walk” signal. The life-saving advice is delivered by a narrator, Pete, and presented onscreen through the actions of vividly colored characters. Techniques such as repetition, rhythm and rhyme are employed throughout to encourage retention for young viewers.

The Cobb County Department of Transportation (CCDOT) has activated six dynamic message signs throughout Marietta and Smyrna. The signs are located on routes that converge on the Interstate 75/U.S. 41 corridor within the greater Cumberland area and play a role in guiding patrons to SunTrust Park and The Battery Atlanta.

The full-color LED signs installed on Cobb Parkway, South Marietta Parkway, Roswell Road and Spring Road provide travel time information for common destinations and indicate the congestion level related to specific routes in real time. Travel times on I-75 and Cobb Parkway appear in digits that are green, yellow or red, depending on the average speed of the roadway. Green digits indicate near free-flow speeds, yellow digits indicate moderate speeds and red digits indicate slow conditions. Public service announcements as well as information related to incidents, construction and special events also will appear on the signs. These messages allow motorists to choose less congested routes.

The historic Concord Road covered bridge near Smyrna will close Thursday, April 13, 2017, from 10 a.m. to noon as part of preparations for its upcoming summer closure, which will begin in two months.

With 7,000 to 10,000 cars traveling it each day, the bridge—which was built in the 1800s—has the highest traffic count of all covered bridges in Georgia combined. Construction to add metal support boxes to reinforce the structure from the inside will begin this June and continue through summer 2017. Additional renovations include siding and roof repairs and guard rail replacement as well as cleaning and painting, at a cost of approximately $630,000 in Special Purpose Local Option Sales Tax (SPLOST) funds.

The Cobb County Department of Transportation (CCDOT) and Cobb County Government officials are on standby to assist the Georgia Department of Transportation (GDOT) and the Fulton County transportation division as our neighboring county deals with the aftereffects of the fire and collapse of a portion of Interstate 85.

“We are thankful that no one was hurt, and we are working with GDOT and all parties involved to move traffic as quickly as possible through our main and secondary roads,” said CCDOT Director Jim Wilgus. “Our traffic management center is monitoring the situation closely and staff is ready to assist as necessary.”

Meadow Drive will close to through traffic at Hembree Road beginning Monday, April 3, 2017. The closure will continue until mid-July. Students currently walking to Pope High School from Meadow Drive will be provided school bus service. In addition to the closure of Meadow Drive, wall construction on the Meadow Drive side of Hembree Road will require closure of the northbound lane of Hembree Road. Northbound traffic will be shifted into existing left turn lanes at this intersection. Signal timing will be adjusted to mitigate traffic delays.

These closures come as part of a CCDOT and Cobb County School District collaborative project to construct a roundabout with right turn bypass lanes on Hembree Road at Pope High School to improve traffic flow and safety for motorists and pedestrians.

The CobbLinc Route 10X implementation plan was approved by the Cobb County Board of Commissioners at its Feb. 28 meeting.

The route will offer faster and more direct service between midtown Atlanta and the Kennesaw State University (KSU) Kennesaw campus and provide connections to Georgia State University, the Georgia Institute of Technology and the Savannah School of Art and Design. Additional stops include Life University, KSU's Marietta campus and SunTrust Park. Route 10X is anticipated to shorten travel time by limiting stops only to major destinations and to relieve the often overcrowded CobbLinc Route 10, which has the highest ridership in the County's transit system and one of the highest in the Southeast at large.
