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.

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.

Multiple roadway closures and shifts will be required for construction of the Georgia Department of Transportation’s Northwest Corridor Express Lanes this weekend (March 3 – 5, 2017). The earliest shift will begin Friday at 7 p.m. on Frey Gin Road from Wylie Drive to Roswell Road. View the full list of closures here.

The Northwest Corridor project will improve travel in the I-75/I-575 corridor by adding 29.7 miles of toll lanes along I-75 from Akers Mill Road to Hickory Grove Road and along I-575 from I-75 to Sixes Road.

Two Express lanes will be built to the west of the existing lanes along I-75 between I-285 and I-575.

The Cobb County Department of Transportation (CCDOT) will share details about three projects at a public information open house Tuesday, March 7, 2017, from 5 to 7 p.m. at the Mountain View Community Center at 3400 Sandy Plains Road, Marietta, 30066. There will be no formal presentation. The projects on display will be Sandy Plains Road at Davis Road (Mountain View Elementary School Relocation), Old Canton Road at Holly Springs Road and Post Oak Tritt Road at Hembree Road. CCDOT personnel will be on-site to answer questions.

The Cobb County Board of Commissioners voted to authorize two new transit routes for the CobbLinc Cumberland Circulator beginning in March 2017. These routes are critical for managing congestion and facilitating economic development in the area. The new routes will provide transit options for the business community during the week and SunTrust visitors for Braves home games.

The Cobb County Department of Transportation (CCDOT) will close the Interstate 75/Windy Hill Road overpass for two weekends while crews complete the new diverging diamond interchange (DDI) crossover.

The bridge will be closed to motorists and pedestrians the weekends of Feb. 18-19 and March 4-5, weather permitting. Ramp access will remain open, allowing motorists right turn access only onto Windy Hill Road.  Detour information will be prominently placed throughout the area.

The intersection of Circle 75 Parkway and Windy Ridge Parkway will close at 9 p.m. Friday, Feb. 10, for the installation and assembly of two pedestrian bridges for The Battery Atlanta. Closures on Circle 75 Parkway between Windy Ridge Parkway and Crescent Parkway and on Windy Ridge Parkway between Cobb Parkway and Interstate North Parkway will prohibit through traffic. The roadways will reopen Monday, Feb. 12, at 5 a.m. Signage and traffic control devices will be in place to direct drivers. Motorists should follow the posted detour or take alternate routes to avoid congestion and delays.

The Cobb County Department of Transportation (CCDOT) recently received $37,975 in grant funding from the Georgia Governor’s Office of Highway Safety (GOHS). The grant, effective through Sept. 30, 2017, will support the Cobb County Pedestrian Safety Campaign. Federal funding will provide 100 percent of eligible costs for the project.

The westbound lanes of Windy Ridge Parkway over I-75 will be closed between Interstate North Parkway and Circle 75 Parkway Thursday, Feb. 2, through Friday, Feb. 10, 2017, from 7:30 a.m. to 4 p.m. daily. Crews will be pouring decks for the widened portion of the bridge on the north side. Signage and traffic control devices will be in place to direct drivers. Motorists should follow the posted detour or take alternate routes to avoid congestion and delays.

The Cobb County Department of Transportation’s transit division, CobbLinc, will transition to the use of MARTA’s Silver Breeze Cards next month to offer increased security and convenience to riders. Beginning Feb. 1, 2017, CobbLinc commuters may take advantage of a month-long promotional offer to purchase a Silver Breeze Card for $1.00—a 50 percent discount. The price of the card will return to $2.00 after the promotion period ends Feb. 28.

Beginning Monday, Jan. 30, 2017, the eastbound travel lanes on Windy Hill Road at the I-75 overpass will shift further right along the south side of the bridge as crews barricade the center of the roadway for construction of walls and sidewalk. The lane shift will be in place until mid-March 2017, after which the lane configuration for eastbound traffic across the I-75 bridge will be two through lanes and one left turn lane to I-75 North. Construction work in the area will take place weekdays from 9 a.m. to 4 p.m. Signage and traffic control devices will be in place to direct drivers. Motorists are strongly encouraged to use alternate routes to avoid congestion and delays.

Beginning Wednesday, Feb. 1, 2017, one lane in each direction will be closed along Interstate North Parkway from Windy Ridge Parkway to the Atlanta Marriott Northwest at Galleria while a new 12-foot sidewalk/multiuse trail is installed along the east side of the roadway.

Lane closures at both ends of the project are already underway due to construction on the Diverging Diamond Interchange (DDI) on the north end of the Interstate North Parkway project and with Windy Ridge Parkway bridge construction on the south end.

Beginning Friday, Jan. 27, 2017, Interstate North Circle will close from just north of its intersection with Interstate North Parkway (near The Weather Channel) to Windy Ridge Parkway until Sunday, March 26, 2017. The 60-day full road closure is required as crews replace a failing corrugated metal pipe with a reinforced concrete pipe. All driveways will remain accessible throughout the closure period. Signage and traffic control devices will be in place to direct drivers. Motorists should follow the posted detour.

A popular entrance into Cumberland Mall is getting a facelift as part of an $8.8 million safety and roadway improvement project along Cumberland Boulevard. 

The Cobb County Department of Transportation (CCDOT) project officially begins the week of January 16, and will take 20 months to complete. The project will improve traffic flow along a 0.85-mile section of Cumberland Boulevard from Akers Mill Road to Spring Hill Road while adding a sidewalk on the north side of the I-285 overpass.

Operations at the CobbLinc Transfer Station will not be affected during the duration of this project.
