All of Gainesville’s roads seemed to lead back to Green Street during a two-hour public discussion Thursday night of the city’s traffic trouble spots. A 10-member Gainesville focus group, created to provide public input on a transportation master plan for the city, held the first of four meetings at the Fair Street Neighborhood Center. The group talked about roads and intersections all through town, including the notoriously busy Jesse Jewell Parkway at E.E. Butler Parkway.
