Highway Widening at Whonnock Creek

The British Columbia Ministry of Transportation and Infrastructure proposes to conduct highway widening and upgrades along an approximately 4 km section of Highway 7 between 266th and 287th Street in Maple Ridge, BC, which requires works in the vicinity of Whonnock Creek. The works include removal of riparian vegetation, replacement of the existing culvert that conveys Whonnock Creek under Highway 7, installation of retaining walls, and infilling approximately 130 m of Whonnock Creek immediately north of the existing highway alignment. Fish habitat offsetting measures are proposed, including construction of a new Whonnock Creek channel to the north of its current alignment, and restoration of riparian habitat at the project site and two offsite locations in Mission and Maple Ridge, BC. The overall project is expected to be constructed over 2 – 3 years, with instream works scheduled for August 1 – September 15 of 2024 and 2025.

Latest update

February 14, 2024 – Fisheries and Oceans Canada issued its Notice of Determination and determined that the project is not likely to cause significant adverse environmental effects.
