Why is WSDOT replacing the culvert under SR 900 at Green Creek?
Green Creek is about 11 feet wide, but as it flows under SR 900 in Renton, it traveled through a narrow 4-by-3 foot culvert. The narrow opening forced the water through the culvert at a high rate of speed, making it harder for fish to pass through.

Contractor crews working for WSDOT have removed the old culvert and replaced it with a 16-by-10 foot culvert. Crews also are restoring the creek bed and native vegetation near the creek.

Fish barrier removal program
The Green Creek culvert is one of more than 1,000 culverts subject to a 2013 U.S. District Court ruling that the state must remove culverts that block fish passage under state roads to restore historical tribal fishing rights.

The End Result
Green Creek now can flow freely under SR 900 in Renton through the larger culvert, allowing fish to swim easily through slower moving water. Native vegetation will provide shade for the creek, which also improves the habitat.

Project Benefits
Environmental - The wider opening of the new culvert will increase the fish habitat and help sockeye, coho, steelhead, sea run cutthroat and resident trout travel Green Creek by creating a slower river flow.
