NW Thompson Rd reopens one year after landslide forced closure

A popular route that connects people from downtown Portland to Skyline Blvd (or vice versa) is now open after being closed for over a year due to a landslide.

NW Thompson Road between Cornell and Skyline Blvd reopened today, says a statement released this morning by Multnomah County. Here’s more from the County:

Last winter’s heavier rainfall led to more landslides than in a typical year. A landslide on the downhill side of N.W. Thompson Road in a rural area threatened to erode the shoulder and eastbound traffic lane. After researching several repair options, Multnomah County chose a product made by Maverick Solutions of Lake Oswego to repair the Thompson Road slide.

After excavating the slide, crews installed layers of plastic netting covered with gravel and lined with bags of earth tied together by a system of plastic connectors. The end result provides the stability of a conventional slide repair and allows the hillside edge to be re-planted, adding strength and environmental benefits.
