The County of Simcoe is undertaking a culvert replacement on 10th Sideroad (County Road 54) in Innisfil. The original structure has been in service since the 1950s and has reached the end of its useful life. The project will also include other improvements, including road improvements, new steel beam guiderails, and a new pavement wearing surface to improve traffic safety and driving comfort over the bridge.​

  • 5th Line from Yonge Street to 10th Sideroad 
  • 5th Line/Reive Boulevard from 10th Sideroad to 4th Line 

No through access. Local access will be maintained for residents of 10th Sideroad and 5th Line throughout the road closure.
