Welcome!
Beginning in late April 2025, the Washington State Department of Transportation will start construction to remove 17 barriers to fish passage and replacing those barriers with 10 new, structures that fish can swim through in south Whatcom and north Skagit counties. This work improves stream connectivity for Unnamed tributaries to Friday Creek, Lake Creek, Unnamed tributary to Lake Creek, and Chuckanut Creek along a 6-mile stretch of Interstate 5, south of Bellingham and north of Burlington.
