SR 161 - Unnamed Tributaries to Hylebos Creek - Fish Passage

Project overview

Three culverts carrying tributaries to Hylebos Creek in Federal Way will be replaced with new structures under SR 161 that do not create a barrier to fish. This work builds on our commitment to remove fish barriers on streams that run under state highways.

Timeline
Spring 2021 - Fall 2024
Project status
Pre-construction
Funding
$24.4 million

What to expect

Replacing the culverts may take up to two years. It will likely require closing one direction of SR 161 around-the-clock for several weekends. Traffic will be reduced to one lane in each direction using the opposite side of the highway during the work. There will also be nightly lane closures. Additional information will be available during construction.
