Mamquam Bridge Deck Rehabilitation

Project Status: Current

The Mamquam River bridge deck is in poor condition and is need of a major rehabilitation to ensure safe long-term roadway conditions.

Construction anticipated to begin in summer of 2026

Budget:
$3 million
Description:

Overview

The Mamquam River Bridge is almost 40 years old, and its bridge deck is in need of rehabilitation to ensure continued satisfactory operating conditions. A consultant was hired in 2023 to do a condition assessment of the bridge deck and the survey revealed significant delamination to the bridge deck and recommended full rehabilitation by the end of 2025. 

In addition to the deck rehabilitation work, the District has finalized a design to enhance active transportation facilities on the Mamquam River Bridge. There is no timeline for implementation of this work, as completion will be dependent on securing grant funding.  

Construction for the bridge deck rehabilitation is scheduled for summer 2026.  

There is no timeline for the active transportation upgrades at this time.

Background/Project Information

Built in 1987, the Mamquam River Bridge is 81-metres long and consists of two traffic lanes with sidewalk on both sides. It is a critical piece of infrastructure for the District, serving as the only municipal roadway connecting the north and south sides of the Mamquam River. 

The bridge deck rehabilitation will involve the removal and full-depth repair of delaminated or deteriorated concrete, the installation of galvanized reinforcing steel, embedding of anodes, and a completely new concrete mat overlay. This work will require single lane alternating traffic for the duration of the work with periodic single-day closures. The contractor will make best efforts to minimize disruptions. 

Impacts:

Residents should anticipate the following impacts during construction, between 7 a.m. and 6 p.m. from Monday to Saturday: 

  • Single lane alternating traffic with potential for queuing and congestion 
  • Vibrations, noise, and dust due to excavation and deck removals 
  • Potential for short-term bridge closures during construction
