Cobb County Government

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.

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 (12/11/17): Due to the winter storm, the bridge will remain closed through Friday, Dec. 15, for completion of the renovation project.

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) 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.
