Highway 1 at Mountain Highway Interchange

Last updated on September 2, 2022

Mountain Highway Interchange

The Mountain Highway overpass has been upgraded to a full Mountain Highway Interchange. This will better distribute traffic and relieve pressure at the Keith Road/Seymour Parkway and Main Street/Dollarton Highway Interchanges. 

Realignment of Mountain Highway provides a third continuous municipal connection across Highway 1, in addition to the Main Street/Dollarton Highway and the Keith Road/Mount Seymour Parkway connections.
