Pine Pass and South Peace Floods

Following severe rain in June 2011, Hwy 97 experienced floods between Pine Pass and 20km south of Chetwynd (a length of 60km), with 73 damaged sites.

Water Management for the Salmon River Dam Decommissioning

During the summer of 2017, BC Hydro’s 60-year old creosote timber dam was completely removed from the Salmon River on Vancouver Island, and the site was re-naturalized. McElhanney designed bypass channels, cofferdams, and river diversion works to use as small a footprint as possible in this narrow and hectic worksite.

Port Mann Highway 1 Roadworks and Detour Designs

During construction, more than 120,000 vehicles drove over the Port Mann Bridge every day, ranging from commuters (travelling 80km/h) to slow-moving construction machinery. The detour designs needed to incorporate HOV lanes, cycling lanes, and dedicated bus and truck ramps, and ensure high-speed and low-speed traffic did not mix.
