Most of the work will take place underneath the bridge. However, some work on the bridge deck will require single-lane, alternating traffic.
To minimize impacts on drivers, these closures will generally be scheduled during months when traffic volumes are lower. The length of closures will also be managed based on traffic conditions.
Expect nightly lane closures so the contractor can safely advance work.
- Monday to Friday: Single-lane alternating traffic between 7 pm and 6 am
- Saturday to Sunday: Single-lane alternating traffic between 7 pm and 8 am
- October to March: Single-lane, alternating traffic may be in place full time day and night as needed to allow the contractor to advance work on the project.
- Occasional full closures of the bridge will occur overnight only between 11 pm and 4 am for up to 15 minutes at a time. For the duration of these closures, traffic will be required to wait on either end of the bridge, or can avoid stoppages by planning to detour over the Mission Bridge or Fraser Bridge.

The Agassiz-Rosedale Bridge carries nearly 15,000 vehicles each day across the Fraser River between Agassiz and Rosedale/Bridal Falls. The bridge, which opened in 1956, carries two lanes of Highway 9 between Highway 1 and Highway 7 and serves local communities on both sides of the Fraser River.
The project will address deterioration of the bridge’s structural steel and concrete, improve drainage and extend the operational service life of the bridge by an estimated 50 years.
Key work will include:
- Replacing deck expansion joints
- Rehabilitating structural components
- Removing corrosion and repairing affected areas
- Improving drainage systems
- Recoating the bridge structure
- Other upgrades to help protect the bridge and extend its service life
The bridge is an important connection for people, goods and communities in the Fraser Valley. These upgrades will help maintain this vital connection and support safer, more reliable travel for decades to come.
