During construction, the Ministry of Transportation and Infrastructure is committed to minimize delays and maximize predictability for all commuters (drivers, transit users, cyclists and pedestrians) by undertaking the majority of work outside of peak traffic periods.  The ministry will not allow lane closures for construction on Sundays, statutory holidays, or during the hours of 5:30 a.m. to 8:00 p.m. Monday through Saturday.  Nighttime work may include 15-30 minute traffic stoppages and advance notice will be provided. The contractor may work throughout the night for some activities, but every effort will be made to keep noise minimal for nearby residents. Ministry staff are monitoring traffic throughout to ensure any delays related to construction are minimal.

Regular updates and advance notification will be provided as needed through DriveBC, social media, traffic advisories, and changeable message signs.

Blasting activity continues – July 2018

On June 11, 2018, drilling and blasting work adjacent to the current highway alignment resumed. The updated construction schedule will see this work continuing into early August.

  • Drilling activities are permitted between 3:00pm & 9:00pm Monday to Friday and 9:00am & 9:00pm Saturdays.
  • Blasting is permitted between 8:00pm & 10:00pm Monday to Saturday. Preparatory work for blasting will be completed throughout the day with possible multiple blasts during the permitted evening time window.
  • No blasting permitted on Sundays or Statutory Holidays

For safety, please obey traffic control personnel.

Warning signs will be as follows:

  • Twelve (12) short whistles, followed by a brief pause;
    • Blast(s) will be detonated;
    • A long whistle indicates all is clear.

New Traffic Pattern at Highway 1 and McKenzie Avenue – May 2018

On June 11th, the northbound lanes on Highway 1 began detouring onto the newly constructed ramps for the future interchange. This new location for northbound highway traffic will be in place until construction of the overpass crossing Highway 1 is completed in summer 2019.

Progress has been made on widening the Galloping Goose Trail and constructing crossings over both McKenzie Avenue and Highway 1, to keep pedestrians and cyclists safer by being separated from vehicle traffic. Pedestrians are now able to use the trail infrastructure to cross Highway 1 and McKenzie Avenue instead of waiting at the Highway 1/McKenzie traffic signal.

While the intersection configuration will be changed, the Ministry of Transportation and Infrastructure expects vehicle traffic to continue to flow at the existing speeds and there will be no changes to the signal timing operations.  The ministry asks drivers to follow signs, watch for workers, and keep moving through the construction site while obeying the construction speed limit of 60 km/h.

The southbound traffic on Highway 1 is expected to be detoured on a new alignment later this summer as construction progresses. These lane shifts will allow crews to excavate the existing highway down and construct the overpass across the highway.
