Culvert Replacement Project Begins on HWY 105 in Raymond
The existing culvert supporting SR 105 between Norris Slough and Willapa Bay is too narrow for the volume of water that typically flows through it. Ocean tides constantly undermine both the culvert and the embankment supporting SR 105, threatening its stability. It also blocks fish trying to swim to habitats upstream.
In addition to removing the culvert and replacing it with a new bridge, crews will pave SR 105 and upgrade guardrail in the area. The project is expected to be complete in fall 2011.
WSDOT asks drivers and commuters to check traffic conditions and try to avoid the project area during construction. For weekly traffic updates in the region, please visit: www.wsdot.wa.gov/Regions/SouthWest/Construction.
