A plan to beautify key downtown Gainesville streets shouldn’t interfere with traffic flow, officials assured City Council on Thursday. “It’s not going to need any traffic study because we’re not going to impact any travel lanes at all,” said Rusty Ligon, Gainesville’s community development director. He and Jessica Tullar, Gainesville’s special projects manager, talked to council members about the project during a work session, showing them a rendering depicting a spruced-up Academy Street at Green Street — an area where traffic backups frequently occur.
