Mamquam Bridge Deck

The 81-meter long Mamquam River Bridge was built in 1987. It is the only municipal roadway connection between the north and south sides of the Squamish.

 A 2023 assessment revealed significant damage to the deck and recommended rehabilitation as soon as possible.

To take advantage of the work already being done, active transportation improvements will be made at the same time, pending the results of a federal grant application. The design for these upgrades was chosen last year.

Completion of the rehabilitation work is scheduled for Summer 2026.

Scope:

The bridge deck rehabilitation includes:

• repairing the bridge deck.
• installing galvanized reinforcing steel
• embedding of anodes.to mitigate corrosion
• adding a new concrete mat overlay.

To maximize efficiency, the District is planning to complete active transportation upgrades at the same time, pending the results of a federal grant application.

Budget: $5 million

Residents should anticipate the following impacts during construction:

• Regular working hours 7 a.m.–6 p.m. Monday to Saturday. 
• Potential for extended bridge closures and detours throughout construction. 
• Vibrations and noise due to compaction and excavation during the above working hours 
• Additional traffic and congestion due to construction activities and vehicles
