More than 33,000 automobiles travel up and down historic Green Street in Gainesville each day, and heavy trucks account for 16 percent of all traffic, about double the statewide average on similar roads. Those numbers provide enough information to understand why city officials, planners and public works crews have long wanted to widen and expand the artery running just a sixth of a mile from Academy Street and E.E. Butler Parkway to Ridgewood Avenue and Riverside Drive. “City staff complains a lot about Green Street to the (Department of Transportation),” Public Works Director David Dockery said.
