Damage to an I-75 bridge has caused a major traffic snarl near Cartersville south of Chattanooga.
Initially all southbound lanes were closed while the damaged overpass was being removed.
Crews on Sunday opened two left lanes of I-75 southbound in Bartow County south of exit 296.
All I-75 southbound lanes were initially closed after the tractor-trailer damaged the Old Grassdale Road overpass.
A determination on traffic patterns for Sunday night was to be made after the work Sunday.
The initial detour was: Southbound traffic will take exit 296 and turn left on Cass-White Road. Traffic will then turn right on to US Highway 411 to reach I-75 at milepost 293.
Georgia Department of Transportation anticipates reopening all southbound lanes of traffic on I-75 Monday. Motorists should expect delays all weekend due to the overpass removal.
