Grant McConachie Way is a three-to-six lane arterial route and thoroughfare in Richmond and Vancouver, British Columbia, Canada. Named for aviator Grant McConachie, it is the primary access road into Vancouver International Airport on Sea Island. It is also one of the three roads entering Vancouver from the south, along with Knight Street and Oak Street. Upon entering Vancouver, the road becomes Southwest Marine Drive.^[2]

The road crosses the Arthur Laing Bridge over the North Arm Fraser River. Its east-west alignment on Sea Island between the Arthur Laing Bridge and the airport is closely paralleled by SkyTrain's Canada Line.^[2] In 2001, interchange improvements were made to provide better access.

While there are at-grade intersections on the route, there have been some talks by YVR to potentially convert the Templeton Street intersection into a proper freeway-like interchange.
