Gainesville officials are looking at ways to ease traffic and congestion for public safety vehicles on some residential streets, including making Hillcrest Avenue and Dyer Street one-way fares, and will discuss the latest proposals at a work session this week. If approved, for example, Hillcrest would only allow travel from Ridgewood Terrace to Northside Drive/North Avenue and eliminate parking on one side. But there has been opposition from some residents about planned changes.
