john.brady@portlandoregon.gov PBOT Traffic Advisory: NW Cornell from below Audubon Society to past first tunnel to remain closed

(Dec. 11, 2016) – The Portland Bureau of Transportation advises the traveling public that further assessment and repair of a landslide will require the closure of NW Cornell from below the Audubon Society to past the first tunnel. Until the area where the slide occurred can be fully assessed, the Portland Bureau of Transportation cannot give an estimate regarding NW Cornell's re-opening.

During last week's storm, a section of slope on the south side of NW Cornell gave way and spread debris onto the roadway. The slide area is approximately fifty feet up the slope and just past the first tunnel. Before re-opening this section of NW Cornell, engineers must assess the stability of the ground above the slide area and determine what repair measures will need to be taken to ensure the roadway's safety. This will require specialized equipment.

The public should use caution and expect delays if traveling in the area. We ask the public to observe all closures and directions by reader boards and flaggers, and use alternate routes.
