What to expect - 32nd Avenue West and Clise Place West

Construction is underway

Since work began in January 2018, crews have:

  • Staged and mobilized equipment on 32nd Avenue West
  • Excavated a pit to access the existing pipe

Next steps:

  • The contractor will close 32nd Avenue West between 33rd Avenue West and Clise Place West to assemble pipe sections (March)
  • Pipe segments will be stored at the Port of Seattle and delivered to 32nd Avenue West as they are needed
  • The contractor will fuse and assemble the full pipeline and guide it up Clise Place West before installing the pipe (lApril)
  • The contractor will use pipe bursting to break up the existing pipe and pull another pipe through the existing pipeline (April)
  • The contractor will reopen all closed driving and parking lanes (May)
  • The contractor will restore the diversion structure that sends excess wastewater and stormwater to the Magnolia Wet Weather Facility
  • The contractor will restore the work area

What to expect:

  • 32nd Avenue West will be closed from 33rd Avenue West to Clise Place West while crews fuse, assemble small segments of pipe and install the pipe (approx. five weeks)
  • Parking will be removed on the west side of Clise Place West immediately prior to pipe bursting (approx. two weeks)
    • Two lanes of narrow traffic will be maintained on Clise Place West between 32nd Avenue West and 33rd Avenue West; please use caution as you are driving through this area
    • Occasionally, crews may need to use flaggers when Clise Place West must be temporarily reduced to one lane between 32nd Avenue West and 33rd Avenue West
  • 32nd Avenue West will be reduced to one lane between the construction zone and West Galer Street during the pipe pull (approx. 3 days)
  • 32nd Avenue West will be reduced to one lane near the construction zone, as needed (throughout construction)
    • There will be limited access on 32nd Avenue West during pipe installation, and intermittent traffic delays of up to 2 hours when the pipe is being installed.
  • Expect increased noise and construction activity along 32nd Avenue West
  • Crews, material and equipment, including a small drill rig, will be in the 32nd Avenue West right-of-way
  • King County's project team will work with any affected neighbors to address impacts during this time
