Barrie residents and commuters should prepare for traffic disruptions starting Monday as Dunlop Street West will be reduced to a single lane for watermain construction. The lane reduction is necessary to replace aging infrastructure and improve water service reliability.
Details of the Lane Closure
The work will affect Dunlop Street West between Highway 400 and Ferndale Drive. Only one lane will be open in each direction during peak hours, with possible full closures at night. The project is expected to last several weeks, weather permitting.
Impact on Traffic
Drivers are advised to expect significant delays, especially during morning and evening commutes. The city recommends using alternate routes such as Essa Road or Mapleview Drive to avoid congestion. Local businesses remain accessible, but access may be restricted at times.
Why This Work Is Necessary
The watermain replacement is part of the city's ongoing infrastructure renewal program. The existing pipes are decades old and prone to breaks, causing service interruptions and road damage. Upgrading them will ensure reliable water supply for years to come.
What Residents Should Know
- Work begins Monday, May 12, 2026.
- Lane reductions will be in place 24/7.
- Pedestrian access will be maintained.
- Emergency vehicles will have priority access.
The city apologizes for the inconvenience and thanks the public for their patience during this essential upgrade.
