Marietta will add flashing yellow arrow signals to improve left hand turns at Wallace Road and North Marietta Parkway near a congested Interstate 75 intersection. Drivers can expect the $316,000 SPLOST project, that includes other intersection upgrades, to take three months to complete. Signals will also be installed on Cobb Parkway at Terrell Mill Road, Airport Industrial Park Drive, Frey’s Gin Road/White Avenue and the Canton Road Connector.
