Holland River Bridge Rehabilitation Update

October 09, 2025
Township of King and Town of Bradford West Gwillimbury

York Region has begun urgent repairs to the Holland River Bridge, at the boundary of the Township of King and Bradford West Gwillimbury. The bridge is jointly owned by York Region and Simcoe County. 

This is a highly travelled corridor and York Region is working to complete this urgent work to ensure the structural integrity of the bridge. While there is no immediate risk to public safety, delaying this work could result in lane closures, weight restrictions or even a full bridge closure.

Why now?

A 2023 inspection of the bridge found structural deterioration. Follow-up assessments showed deterioration had progressed more rapidly than anticipated, requiring immediate repairs to maintain the bridge’s structural integrity. Rapid deterioration was primarily caused by leaking expansion joints allowing road salt to reach the structure.

Construction Schedule 

Work includes repairs to structural components of the bridge. Lanes have been reduced so sections of the bridge deck will be completely removed. It is not possible to re-open all lanes to traffic until the bridge deck has been re-instated at the end of each stage. 

There may be periods of perceived inactivity, as much of the work will occur below the bridge and involves materials like concrete and grout that need time to set and cure before work can proceed. 

Construction began on Monday, September 15, 2025, and will continue for approximately seven months in two stages. Stage 1, work on the south side of the bridge, is underway and expected to be complete in mid-December. Stage 2, work on the north side of the bridge, will begin in mid-July and expected to be complete in mid-October. 

The gap between stages is due to winter conditions, where this type of work cannot be carried out as efficiently and restrictions on in-water work during fish spawning season. The bridge will be restored to four lanes during this period. The Region is seeking an exemption related to the in-water work restrictions. If successful, this would advance timing of Stage 2.

Timeline of work periods for the Holland River Bridge construction

Staff are working to find ways to expedite work. While the contractor will work Monday to Saturday and most Sundays, it has been determined extending working hours further would have a minimal impact to the schedule.

Efforts to Minimize Impacts to Travellers 

  • Continuing to monitor traffic conditions and making adjustments to help with the flow of traffic, including:
    • Temporarily engaged Pay Duty Officers to assist during peak hours
    • Travel apps updated to indicate lane restrictions
    • Signal timing adjustments
