Two new Cobb road closures have been announced, according to Cobb’s new real-time traffic app, CobbCommute.com/full#.

From Aug. 10 to Oct. 10, Busbee Drive from Townpark Lane to George Busbee Parkway will be closed between 3443 and 3453 Busbee Drive to build a roundabout for Skip Spann Connector.

Starting in mid-August, there will be daily lane closures from 9 a.m. to 4 p.m. as the Cobb Marietta Water Authority contractor installs a 54-inch water main along Lower Roswell and Terrell Mill roads from Fairfield to Cobb Parkway.

Through the end of this month, Riverside Drive from Johnson Ferry Road to River Valley Road is closed to through traffic while Sandy Springs makes road improvements.

The detour is River Valley Road.
