Fort Nelson River Bridge

2010-Ongoing | Fort Nelson, BC – Located approximately 70KM northwest of Fort Nelson on Highway 77, the Fort Nelson River Bridge provides access to the Liard Natural Gas basin and is the only road connection between BC and the Northwest Territories. The bridge is being replaced as part of BC’s 10-year transportation plan, “BC on the Move.” The new bridge will accommodate increasingly heavy and large loads needed by industry, and will improve the capacity and reliability of the highway.

McElhanney is the prime consultant for the detailed engineering phase, and a subconsultant for the substructure assessment. Our services included:

  • Substructure assessment and developing construction staging / superstructure replacement options
  • Conceptual and detailed highway and bridge design; strengthening design for substructures
  • Geotechnical engineering for land piers (subconsultant: GeoNorth) and liaison with the Ministry’s geotechnical engineer for river piers
  • Assisting in utility relocation (Northwest Tel’s fiber optic line)
  • Assisting with public consultation
  • Preparation of tender documents
  • Engineering services during construction

The replacement design was tailored to Northern BC’s harsh weather conditions, and McElhanney minimized environmental impacts and traffic disruptions through careful staging and construction schemes.

Keeping drivers safe is a top priority for this project. Improving the Fort Nelson bridge will make Highway 77 much safer for both travelers and commercial traffic.
