The Roswell City Council has approved spending $13,200 for a pilot trolley service that will carry riders around the historic district downtown on weekend evenings starting Friday.

The city has retained Historic Marietta Trolley LLC to run the free service from 5 to 11 p.m. Fridays and Saturdays, May 12-Aug. 5. The trolley will start at City Hall and head over to Mimosa Boulevard, where it will run south to Bulloch Avenue and back; and then over Canton and Green streets as far north as Woodstock Street. Trolley signs will be placed at each of the 10 stops along the route.

The vehicle will operate a total of 24 days during the 90-day trial, generating ridership data that will help to city decide whether to implement the service permanently. The city intends to pay only for the pilot project and will look into sources of long-term funding, such as passenger fares, sponsorships or by groups such as the Roswell Convention & Visitors Bureau, officials said.

“I don’t believe there’s any council member suggesting in the long term that this be taxpayer-funded,” Mayor Jere Wood said at Monday night’s council meeting.
