Traffic patterns are due to change as a new loop ramp opens at McKenzie Interchange this Saturday.

BC’s Ministry of Transportation says that effective August 15, the exit to McKenzie Ave off Highway 1 southbound will be via the new loop ramp at the McKenzie Interchange.

Traffic signals will be turned off at the Interchange overnight from Friday evening into Saturday morning as they are reconfigured to the new traffic flow.

The Ministry is asking that drivers use extra caution during this period as they travel through the interchange and obey directions from traffic control personnel.

With the loop ramp open, the exit from Highway 1 southbound to McKenzie Avenue and Admirals Road remains in the same location.

Signage will direct drivers to the correct lane upon exiting the highway—staying right for Admirals Road or proceeding around the loop directly onto the overpass for McKenzie Avenue.

The controversial interchange project originally started in September 2016 with an expected completion date of late 2018.

It was delayed twice over the course of construction, with $11 million added to its initial budget of $85 million, for a total of $96 million.

In a statement Friday afternoon, the Ministry of Transportation thanked people in advance for their patience during the traffic pattern change.

The Ministry added that more updates will be provided in coming weeks as the project nears completion.
