Marietta Daily Journal reports that GDOT commissioner Russell McMurry is optimistic about the I-75 toll lanes project in Cobb County. “The $834 million, 30-mile toll lanes will be transformational in relieving traffic congestion, McMurry said, by giving drivers the option of using the lanes during the busiest times of the day. Express bus service will also be able to use the lanes, another benefit of the project.” McMurray made the remarks during an August 18 event celebrating GDOT’s one-hundredth anniversary.
