Highway 1 at Mountain Highway Interchange

Fern Street Overpass Demolition

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.

Mountain Highway Landscaping 2019/2020

Due to heavy rainfall and saturated ground conditions, there were locations within the project where the top soil had slipped. Once the ground conditions were dry enough and less rain was forecasted, the affected areas were redressed and landscaped accordingly under the construction contract 1 year warranty. It is important to note that the slopes were inspected and determined to be in stable condition.
