King William Street Reconstruction

Work completed between June 1 and June 5, 2026:

• Traffic control was set up along King William Street, including closing the southbound lane and redirecting traffic to the northbound lane, maintaining one lane of travel in each direction.

• Pavement, curbs, and sidewalks were removed along the southbound lane between Rogers Cove Drive and Highway 60. Some curbs and asphalt at the King William Street and Rogers Cove Drive intersection still need to be removed.
• Traffic signal timing was adjusted to keep traffic moving smoothly, including updated turn and through-movement phases for southbound traffic.

Work projected between June 8 and June 12, 2026:

• Both directions of traffic will be shifted onto the southbound lane.
• Once the traffic switch is complete, removal of pavement, curbs, and sidewalks will begin on the northbound lane.

King William Street Reconstruction Update: Two-Way Traffic to be Maintained During Construction

The District of Muskoka has revised its traffic management plan for the King William Street reconstruction project and will maintain one northbound lane and one southbound lane through the construction area while work progresses.

The original plan called for King William Street to operate as one-way southbound traffic only between Scott Street and Highway 60. Following discussions with local businesses, the District worked with the contractor to review the traffic management plan and identify a solution that would maintain two-way access through the construction zone.

To support this revised approach, additional traffic control measures will be implemented, including temporary signal modifications, additional traffic control staff, and specialized traffic control equipment.

What to Expect

• One northbound lane and one southbound lane will be maintained through the construction area.
• Lane closures are anticipated to begin this week once traffic control measures are finalized.
• Access to all businesses will be maintained throughout construction.
• Significant traffic delays and congestion are expected in both directions during contractor hours, particularly Monday through Thursday
• Traffic conditions are expected to improve during evenings and weekends when construction activities are reduced or paused.
• Motorists are encouraged to allow extra travel time and consider alternative routes where possible.

The District and its contractor will continue to monitor traffic conditions and project operations throughout construction and make adjustments where practical and appropriate.

The District appreciates the feedback received from local businesses and remains committed to working collaboratively with the community throughout construction.

The contractor continues to prepare the site this week ahead of major construction work.

King William Street is now scheduled to be partially closed and limited to one-way traffic as early as the week of June 1. Once this is in place, northbound traffic on King William Street from Scott Street to Highway 60 will be closed. Southbound traffic will remain open. This partial road closure will help ensure work can be completed as efficiently as possible, while maintaining access to all businesses during construction.

Additional details will be shared as construction gets underway.

Access to all businesses will be maintained during construction.

Thank you to everyone who came to our construction café on May 6.

The contractor is scheduled to begin site set-up as early as the week of May 19.

Major construction, including parts of King William Street being partially closed and limited to one-way traffic, is scheduled to start as early as the week of May 25.
