Highway 1 - Lower Lynn Improvements

Highway 1 connects Metro Vancouver to the North Shore, the Horseshoe Bay ferry terminal and Highway 99. It is a vital local, regional and provincial corridor for people, services and goods. Improvements will address safety, queuing and delays and will help to improve travel times along Highway 1 and the Lower Lynn Interchanges.

The Highway 1 – Lower Lynn Interchanges were designed and built over 50 years ago and are in need of upgrades or replacement. The Mountain Highway/Lynn Creek, Keith Road/Seymour Parkway and Main Street/Dollarton Highway Interchanges will be upgraded in four phases.

Project Cost:

The estimated total cost for this project is $198 million. Funding for the project is being provided by the Province of B.C. ($76.7 million), Government of Canada ($66.6 million) and the District of North Vancouver ($54.7 million).
