This project removes the existing, outdated culvert along US 101 just south of Forks with a concrete-boxed structure for improved fish passage as part of WSDOT efforts to improve fish migration.
Construction is anticipated to begin spring of 2020 and be completed later that fall. Drivers will pass through the active construction zone by way of a single lane bypass controlled by a temporary signal until all work is complete.
Travelers should be aware of another nearby WSDOT fish barrier correction project in its second year of construction further south along US 101
Needs & Benefits
The existing culvert runs from an unnamed tributary to Hoh River in Jefferson County and has been identified by WSDOT and the Washington State Department of Fish and Wildlife as a barrier to fish needing correction. It is roughly 60 percent passable in its current condition and species such as bull trout, steelhead, coho and cutthroat salmon have been identified at this location.
This work is part of WSDOT’s Fish Passage Barrier Removal Program, which identifies and removes barriers to fish caused by culverts under state highways. WSDOT works in partnership with the Washington Department of Fish and Wildlife to identify culverts that, once replaced, will increase fish habitat. This particular project has a potential habitat gain for fish of approximately two miles.
During construction, travelers will use a one-lane detour at the site that will be controlled by a temporary signal. Travelers should expect minor delays, reduced speed limits and occasional roadway closures. Any roadway closures will be announced in advance.
The End Result
The new 5’x5’, 55-foot long concrete boxed culvert is expected to open nearly two miles of potential fish habitat. This fish passage project will help restore the streambeds to a more natural state and improve fish passage for local migratory fish.
