$33M Agassiz-Rosedale Bridge upgrades expected to start Monday

AGASSIZ — Crews are set to upgrade travel for the nearly 15,000 vehicles that drive daily across the Agassiz-Rosedale Bridge this fall.

The province has awarded a $33 million contract to B.C.-based Graham Infrastructure LP to address the bridge’s deteriorating structural steel and concrete, as well as improve drainage and extend its service life by roughly half a century.

“The Agassiz-Rosedale Bridge is an important connection for people, goods and communities in the Fraser Valley,” said the Ministry of Transportation and Transit. “These upgrades will help maintain this vital connection and support safer, more reliable travel for decades to come.”

Some bridge deck work will require single-lane alternating traffic scheduled overnight between 7 p.m. and 6 a.m. on weekdays and up to 8 a.m. on weekends.

The traffic pattern changes may remain in place 24/7 during the winter months to support project work.

The length of lane closures will also be dependent on traffic conditions. Delays are estimated to be about 15 minutes.

Any periods of no traffic – aside from emergency vehicles – will only take place overnight between 11 p.m. and 4 a.m. for as much as 15 minutes at a time. DriveBC will post notices when they occur. Detours can be made over the Mission or Fraser Bridges if needed.

Construction is expected to begin as early as this Monday, September 21, and may take approximately three years to complete.

The bridge opened in 1956 and carries two lanes of Highway 9 between Highways 1 and 7, serving communities on both sides of the Fraser River.
