York Region has begun urgent repairs to the Holland River Bridge, which is jointly owned by York Region and Simcoe County.
York Region is working to complete this critical 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.
Plan Ahead
Lanes on the Holland River Bridge have been reduced, expect delays and allow for extra travel time.
About the project
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.
Work includes repairs to structural components of the bridge including the bridge deck. Traffic lanes have been reduced to one lane in each direction as sections of the bridge deck are being 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 of work.
There may appear to be quiet periods of work, as much of the work is happening below the bridge and with materials such as concrete and grout that need time to cure before work can proceed.
Duration
Construction began on Monday, September 15, 2025, and will continue for approximately seven months, in two stages.
Stage 1 - South side of the bridge
- Start Date: September 15, 2025
- Anticipated Completion: Mid-December 2025
Stage 2 - North side of the bridge
- Start Date: Mid-July 2026
- Anticipated Completion: Mid-October 2026
The pause between the two stages is due to winter conditions and restrictions on in-water work during fish spawning season in the spring. During the pause, the bridge will be restored to four lanes.
Minimizing impact to travellers
- York Region is continuing to monitor traffic conditions and making adjustments to help with the flow of traffic, including:
- Temporary Pay Duty Officers will assist during peak hours
- Travel apps updated to show lane restrictions
- Signal timing adjustments
- Restricted left turn from Highway 11 to Canal Road and from Canal Road to Bridge Street (with the exception of farm vehicles)
- Temporarily closing Toll Road, local traffic is permitted
- Installed ‘No Stopping Signs’ along Pumphouse Road and Graham Sideroad
- A temporary speed limit is in place for safety
- Access to homes and businesses may be temporarily interrupted
- There is no impact to water services
Project notices
- Notice of Temporary Road Closure – Toll Road – Oct 9, 2025

Frequently asked questions
Is it possible to re-open all the lanes of traffic?
Due to nature of the rehabilitation work the lanes cannot be re-opened until the work on the bridge deck has been completed.
Why is there a pause between the two stages of work and will all the lanes be reopened during this time?
Work will be paused between mid-December 2025 to mid-July 2026. Cold winter conditions limit the work and there are restrictions for working in-water during fish spawning season. The bridge will be restored to four lanes during the pause.
Can the repair work be done at night?
Due to the complex nature of the work, including sections of the bridge deck being removed and to ensure a safe working environment, the work will occur during daylight hours.
The contractor is working Monday to Saturday, and most Sundays, and it has been determined extending working hours further would have a minimal impact to the schedule.
Why does it look like work has stopped or slowed?
There will be periods where work appears to have slowed and you may not see workers because:
- Work is happening below the bridge, away from driver line of sight
- Work may not be happening due to inclement weather; after a weather event, such as a heavy rainfall, the contractor needs to wait for the work zone to dry
- Some materials such as concrete and grout require time to set and cure before work can proceed. Curing is critical to ensure structural integrity and long-term durability of the materials
How will real-time updates on construction progress and unexpected delays be provided to help travellers plan their trip?
Travellers are encouraged to use traffic and navigation tools such as Waze. York Region provides real-time traffic and road information in open data, used by many apps.
Updates are posted on portable message boards located near the work area.
What traffic flow measures are in place during the lane reductions?
Traffic is guided by temporary line markings, concrete barriers, temporary speed limits and traffic signal timing adjustments to help the flow of traffic. Lane reductions are necessary to complete this work; there are no full lane closures planned. Paid Duty Officers are onsite to help manage the flow of traffic during peak hours.
