The District of Muskoka is reconstructing King William Street from Scott Street to Highway 60. Construction is scheduled to begin in June and is expected to be completed by the end of 2026.

The project is part of the District's investment in essential systems that make housing possible and will increase capacity to support 3,200 new homes in the Town of Huntsville.

Replacement and upgrades to aging water, wastewater and transportation infrastructure will boost housing and the economy locally and support the long-term health of Muskoka's lakes, rivers and communities.

Work will include removing and replacing:

  • Aboveground: road, traffic signals

  • Underground: sanitary and storm sewers, watermains

  • Streetscape: curbs, sidewalks, boulevards

As with any construction project, disruptions are to be expected, there will be impacts to the community and the District is committed to minimizing disruption wherever possible.


What You Need to Know

Traffic impacts

  • Two-way traffic will be maintained through the construction area. Expect significant delays in both directions.
  • One northbound lane and one southbound lane will be maintained between Scott Street and Highway 60 while construction is underway.
  • Motorists should expect traffic delays and congestion in both directions and are encouraged to allow extra travel time or consider alternative routes where possible.

Access maintained

  • Access to all businesses will be maintained during construction.
  • Following discussions with local businesses, the traffic management plan was revised to maintain two-way access through the construction area while work progresses.
  • Pedestrian crossings at Rogers Cove Drive and the Huntsville Place Mall entrance will remain open.

Updates and scheduling

  • Municipal 511 will be updated to help keep Google Maps and Waze current.

  • Delaysmayoccur due to unforeseen conditions. Advance notice will be provided where possible.
