Impacts at 148 Street and Summit Drive

At the first work location (green area on map), we'll first construct a shaft, a tunnel boring machine (TBM) will be lowered into the shaft, and then move into the tunneling phase.

During this work, you'll encounter:

  • A closed sidewalk on the north side of Summit Drive with detoured pedestrian traffic (orange line on map)
  • Westbound lane closure on Summit Drive (red line on map)
  • Regular construction activities from Monday to Saturday, 7:00 a.m. to 6:00 p.m. 
  • Work taking place 24 hours a day during the tunneling period
    • The tunneling period is estimated to start 3 months after the start of the shaft construction
    • There are 3 phases to the 24 hours a day tunneling. Here are the estimated timelines:
      • Fall 2020 to Spring 2021 – 147 days
      • Spring 2021 to Summer 2021 – 66 days
      • Fall 2021 – 41 days
  • Heavy traffic along the haul route; tandem trucks and equipment will be coming down the haul route 5-7 times a day


​Haul route

The haul route for this work location is as follows:

  • Trucks will enter the worksite on Summit Drive from 149 Street.
  • Trucks will exit the work area at 148 Street and continue south and exit to 149 Street via 100 Avenue.
