NW Thompson Road closure update

Friday, 1/27/12 - 2:43 pm

A short section of NW Thompson Road remains closed between NW Cornell Road and NW Skyline Blvd. due to a landslide that occurred in 2011. Multnomah County has completed the landslide repair and repaved the road in the repair zone. However, more tasks need to be completed before the road can be reopened:

  • Re-plant the slope on the downhill side of the road to add stability and return it to its natural state
  • Rebuild the drainage ditch on the uphill side of the road
  • Place protective concrete barriers on the outside shoulder
  • Put down temporary lane striping

We had hoped to reopen Thompson Road by the end of this month. However, last week's severe storm created new urgent tasks for our road crews that will impact the reopening schedule for Thompson Road.

  • Several culverts under Thompson Road a half mile east of the slide were damaged and are being dug out and replaced
  • Crews have needed to respond to storm damage elsewhere on our road system, including downed trees, landslides, and washouts

We estimate that Thompson Road will reopen in the next one to two months. The main factor impacting the schedule will be weather conditions. Good weather will allow our crews to catch up on storm repairs and complete the Thompson work.

We regret the inconvenience this road closure has created for neighbors and road users. We will send you an update on the reopening schedule as soon as we have new information.
