Circle 75 temporary road closure begins Jan. 19

Circle 75 Parkway, from Cobb Parkway to Heritage Court, will be closed to through traffic from Thursday, Jan. 19, to Wednesday, Jan. 25, 2017, for work on the I-285 Multiuse Bridge. To access Circle 75 from Cobb Parkway, motorists should take Windy Ridge Parkway. Access to the 900 building and Hampton Inn will be maintained at all times. Signage and traffic control devices will be in place to direct drivers.

I-285 WB Ramp to I-75 NB Weekend Closure

The two right lanes of the I-285 westbound ramp to I-75 northbound will be closed Sunday, Nov. 20, 2016, from 5 a.m. to 8 p.m. (An additional closure may be required Monday, Nov. 21, 2016, from 9 p.m. through 5 a.m. Tuesday, Nov. 22, 2016, to complete the work.) The right lane from I-285 eastbound to I-75 northbound will be closed to allow traffic to shift over from the double lane closure. Signage and traffic control devices will be in place to direct drivers.

These lane closures will allow for the removal of a beam from the Windy Ridge Parkway Bridge on the north side to prepare for girder installation the following week. The Windy Ridge Parkway Bridge project consists of the widening of the existing bridge over the I-75 and I-285 ramps to provide enhanced pedestrian accommodations and greenway space. Completion is expected in 2017.

Rockwood Drive closure to begin Monday, Oct. 17

Rockwood Drive in Marietta, between Jamerson Road and Gray Rock Drive, will be closed to traffic Monday, Oct. 17 through Monday, Nov.14. 

The existing 48-inch corrugated metal pipe on Rockwood Drive has failed, causing settlement in the roadway.  This project includes replacing the existing pipe with a 48-inch reinforced concrete pipe, constructing new headwalls and repaving the failure area.

Please use detour routes to avoid the closure location.
