The Downtown Reimagined Weekly Dispatch – October 16, 2026

Work continues to move forward on the Downtown Reimagined project, with several construction milestones reached this week. As crews prepare for the next phase of watermain installation, residents and visitors are advised of an upcoming closure on Mountain Street beginning Monday, October 19.

Current Work

Construction continues to progress across the Downtown Reimagined project area, with several milestones reached this week:

• Main Street West: Watermain installation is complete, with only final connections remaining.

• Elm Street: Crews have completed the remaining trench restoration.

• Elm Street and Mountain Street Intersection: Overnight work is complete, with watermain installation extending nearly one-third of the way along Mountain Street between Elm Street and Main Street.

Looking Ahead – Week of October 19

Mountain Street Closure (Elm Street to Main Street)

Beginning Monday, October 19, both crews will focus on watermain installation along Mountain Street between Elm Street and Main Street.

Crews will use hydro-vac and hand excavation to carefully work around existing underground utilities. As these methods take longer than standard excavation, this phase is expected to take approximately four to six weeks.

Traffic Impacts

• Mountain Street (Elm Street to Main Street): Fully closed to through traffic beginning Monday, October 19, for approximately four to six weeks.

• Motorists: Follow designated detours and posted signage.

• Heavy Trucks: Vehicles travelling between Mountain Road and the QEW must follow the regional truck detour plan.

• Parking: Downtown parking lots will remain accessible via alternate routes, but not from Mountain Street.

• Businesses: Downtown businesses remain open, with sidewalk access maintained throughout construction.
