Completed Norris Slough passage strengthens roadway, gets fish to Willapa Bay

RAYMOND – Drivers and fish alike can plan for easier passage on State Route 105 near Raymond as work wraps up on a new bridge designed for a smoother ride for drivers and easier passage for spawning fish.

On Wednesday, Jan. 25, the Washington State Department of Transportation will reopen SR 105 to two lanes of traffic and raise the speed limit from 25 mph to 45 mph on this stretch of highway.

During the past nine months, a traffic signal directed SR 105 drivers across a temporary, single-lane bridge, while crews replace an undersized culvert with a new 87-foot-long concrete bridge.

The new bridge connects the Norris Slough to Willapa Bay and allows fish to pass freely upstream to their spawning grounds in the bay.

“This new bridge restores an important fish passage, but it also protects the roadway and taxpayer dollars,” said Project Engineer Colin Newell. “Our maintenance crews routinely repaired this patch of road, which was eroding because of the narrow culvert. The new bridge carries the roadway clear over the slough, which will reduce maintenance costs – it benefits everyone.”

Crews will return in spring when dry weather allows final paving work to be complete.

The $2.3-million project was funded through federal and state highway improvement funds.
