Closure will allow for the completion of the $13 million new bridge and reconstruction of a railroad crossing over Canton Road.
Traffic will be detoured along the Canton Road Connector, with another route available along Allgood Road and Sawyer Road.
The closure was specifically delayed a week to allow back-to-school traffic to be warned by signs in the area before the closure begins.
The city’s Public Works Committee chaired by councilman Jim King approved the closure 3-0. Final approval before the full City Council is scheduled for Aug. 14.
The new bridge has already started to be put into place, with one lane closed for several months, but the final pieces are ready to be added, city engineer Jim Wilgus said.
The project is twofold, to replace a bridge built in the early 1940s and improve the traffic flow in the area, including realigning the railroad crossing.
The existing railroad track cuts across the intersection at an angle. The new one is designed to allow drivers to pass over it faster.
Wilgus said the finished bridge will be longer than the original and offer the possibility of widening Cobb Parkway in the future.
The construction is a Georgia Department of Transportation project that contracted with C.W. Matthews of Marietta.
Clarence Harris with GDOT said the project will be completed by the end of March.
