In years past, when station wagons served as ambulances, passage along narrow Hillcrest Avenue in Gainesville might have been OK. “Super-large, tandem-wheeled SUV-type trucks are used for that kind of thing now,” public works director David Dockery said. It’s the width of emergency vehicles, as well as trash trucks, that aren’t meshing well with cars and other vehicles parked on either side of the street. City officials are looking at ways to ease the tight conditions, particularly making Hillcrest one-way, allowing travel only from Ridgewood Terrace to Northside Drive/North Avenue and eliminating parking on one side.
