Repairs to Hoh River Road - West Twin Creek Crossing

Olympic National Park » Repairs to Hoh River Road - West Twin Creek Crossing » Document List

The West Twin Creek Bridge project on the Hoh Road is now completed and two lane access to the Hoh area of Olympic National Park has been restored.

A severe storm on November 6, 2007 washed out two large culverts (or corrugated metal pipes) under the Hoh River Road. High water and storm debris plugged the culverts, causing the creek to overflow and erode the road. This led to a large (75 feet long and 25 feet deep) washout. The washout was spanned by a temporary one-lane bridge until the permanent bridge was completed in spring 2008.

An environmental assessment was completed for the project July 2007. The selected alternative was to construct a bridge over the crossing to allow for more sustainable access and to provide fish passage to the upper creek. The project work began in September during low flows and continued through the winter.
