Frontier Street Closed Between 
Sable Avenue & Pine Cone Avenue

August 25 through Middle October 2025


Beginning Monday, August 25, 2025, Frontier Street (CR 15) will be closed for road improvements between Sable Avenue and Pine Cone Avenue. This work is part of the development of the Frontier Estates subdivision. Barring any unforeseen issues and weather permitting, this closure is expected to last through mid-October 2025.

This closure will affect only through traffic on Frontier Street between Sable Avenue and Pine Cone Avenue. Local traffic and residents can still reach their destinations, but might need to take a detour until the work is finished. Also, please know that the regional trail will be closed in the work zone area.

The main detour routes will use Sable Avenue (CR 22) and Pine Cone Avenue (CR 20). Signage will be in place along the detour route to help direct travelers. 

Motorists, pedestrians, and cyclists are urged to pay close attention to detour and traffic control signs and, if possible, avoid this section of Frontier Street altogether.

For more information on this project, please call Shawn Kronebusch, Redland's Project Manager, at 720-283-6783.
