Project Details:

The Church Creek Fish Passage project consisted of the replacement of an existing 6 ft x 8 ft box culvert under SR 532 in Stanwood.  The culvert was located 50 ft below the existing road grade, requiring a large open-cut excavation during a brief (two week) closure of SR 532.  The existing culvert was replaced with a 200 ft long precast split box culvert with 14 ft x 30 ft inside dimensions and precast wingwalls.  Other work included a temporary bypass of Church Creek, streambed restoration and improvements, landscaping, guardrail, and access road improvements.
