A full road closure on Essa Road between Tiffin Street and Gowan Street is planned for May 14 to 16.
The city says G.E. Binnie Haulage and Excavation and its sub-contractors, operating on behalf of the City of Barrie, will be implementing the closure on those three days from 7 a.m. to 7 p.m. each day.
The closure is associated with the city's Allandale Transit Terminal Project.
Emergency services will have access to respond within the closure but will not be permitted to travel through it, according to a city news release.
Detour route in effect: Tiffin Street – Innisfil Street.
