Polk Street Extension At Whitlock Avenue Marietta, Georgia - MariettaAll other nearby intersections have the proper signage except this one. Drivers making a right from Polk St Ext onto Whitlock Avenue (usually a long line of them during rush) on the green light just blow through and drivers making a left onto Whitlock from cross street Old Dallas Rd have to try to inch their way in on Whitlock on the same green light. Polk Streeters should have a YIELD sign on their side. I have seen several near misses due to this, several involving my family. Check every other similar intersection around town (e.g. Whitlock and Marietta Pkwy, Polk and Marietta Pkwy, Lindley/Kirkpatrick and Whitlock). ALL have a YIELD sign for the right-turning traffic. Please either install a YIELD sign or give left-turners from Polk St Exn and Old Dallas Rd green arrow light signals like Whitlock and Manning at the high school.
