Overnight surveying to interrupt I-85 traffic this weekend

Interstate 85 traffic will be slowed overnights for survey work 11 p.m. to 4 a.m. this weekend between Old Peachtree Road, Exit 109 and Hamilton Mill Road, exit 120 in Suwanee. Traffic will be slowed down and stopped for no more than 5 minutes at a time to allow surveyors to “shoot 3 point levels” of the interstate.
