Contractor crews working for WSDOT installed a larger culvert that carries West Fork Hylebos Creek under SR 99 near Federal Way.
Crews also realigned and regraded the creek to slow the water flow.
The new 10-by-20 foot wide culvert and rebuilt stream allows Chinook, coho and chum salmon to more easily pass under SR 99.
The previous culvert was installed in 1925 and often became clogged with debris and branches, creating impassable barriers for fish.
| Protects Environment
Replacing the culvert and rebuilding the stream helps protect and preserve salmon habitat:
-a larger culvert allows fish to more easily pass under SR 99.
-a slower-moving stream creates more areas for spawning fish to rest.
-fish can now access several additional miles of the stream and eventually make their way into the West Hylebos Wetland Park.
-Non-native bushes and trees were removed and native bushes and trees planted.
-Improved habitat for other animals including frogs, birds and small mammals.
