The
McKenzie Interchange Project is a grade-separated interchange on the Trans-Canada
Highway at the intersection with Admirals Road and McKenzie Avenue in Saanich.
The intersection is the number one bottleneck in the province of British
Columbia outside of the Lower Mainland. The project will improve traffic
flow of passenger, transit and goods movement vehicles. Safety of pedestrians
and cyclists will also be enhanced as part of the project.
In the first stage of the recently completed McKenzie Interchange project,
the embankment for Galloping Goose Trail (a bicycle/hiking trail which
parallels the Trans-Canada Highway) was elevated and taken across McKenzie
Avenue on a new bridge structure.
The abutments for this bridge and a portion of the new embankment along
the highway are supported by Reinforced Earth® walls. These walls were
built in two stages to allow for the consolidation of the foundation over
the construction period. The second phase of this project will incorporate
additional Reinforced Earth walls at the abutment of a second bridge carrying
the pedestrian traffic across the upgraded TransCanada Highway.
