UPDATE: The accident has been cleared from the interstate but traffic remains backed up.
Commuters trying to get home from metro Atlanta or the Kennesaw area this evening are in for a rough commute. A two-vehicle accident on 75 north has the left lane blocked as of 5:05 p.m. Your best bet: Bail off 75 as soon as you can for U.S. 41. It is congested as well but might be moving faster than the 75 traffic.
