Read all project updates below.

The Duckabush estuary has been degraded for almost 100 years by a wall of highway fill that nearly severs the ecological connection of the estuary to the tidelands.

The Washington Department of Fish and Wildlife (WDFW), in partnership with the U.S. Army Corps of Engineers (Corps) and the Hood Canal Salmon Enhancement Group (HCSEG), is proposing an estuary restoration project to correct this legacy environmental impact. The estuary is important habitat for salmon and other fish and wildlife, including several species listed under the federal Endangered Species Act. The restoration project would reconnect the Duckabush River to neighboring floodplains and wetlands by modifying local roads, elevating Highway 101 onto an estuary spanning bridge, and reconnecting historical channels.

Restoration activities are primarily on public land at the Duckabush Wildlife Area Unit managed by WDFW. Project design is expected to be complete in 2023. Once construction funding is secured, construction would take about four years.  

Project benefits

  • Improve habitat for fish and wildlife, including Hood Canal summer chum and Chinook salmon, a main food source for endangered Southern Resident Killer Whales.
  • Reduce seasonal flooding in the area, benefitting both public and private property.
  • Provide a modernized highway design that meets current safety standards.
  • Create approximately 1,300 jobs and support the local economy.
  • Establish a wildlife corridor under the highway to improve habitat connectivity and reduce wildlife-vehicle collisions.

Project design

A preliminary project design was developed by WDFW, WSDOT, and the U.S. Army Corps of Engineers in coordination with local Tribes, County government, and local conservation organizations. The current design partnership is incorporating site-specific data and public input to refine the preliminary design. 

 Preliminary project features include:

  • Restoration and reconnection of several historic tidal and river channels to improve fish and wildlife habitat.
  • A new 1,600-foot-long estuary-spanning bridge designed to accommodate future high tide and flood conditions. 
  • Wider highway shoulders, a re-designed intersection at Duckabush Road, and a left turn lane from northbound Highway 101 onto Duckabush Road.
  • Additional public parking next to Duckabush Road at the north end of the new bridge to provide access to the Wildlife Area.

A virtual public meeting showcasing the preliminary design was held on Sept. 22, 2021. People can review the meeting's presentation (PDF) for more details.

An in-person community open house providing an update on the project was held on May 4, 2024. People can review the open house materials below for more details.

Environmental review

Consistent with the State Environmental Policy Act (SEPA) RCW 43.21C, the WDFW determined that this project may have a significant adverse impact on the environment for which an Environmental Impact Statement (EIS) must be prepared.

WDFW adopted the Puget Sound Nearshore Ecosystem Restoration: Final Integrated Feasibility Report and Environmental Impact Statement (IFR/EIS) following WAC 197-11-630 adoption procedures. The final IFR/EIS was issued by the US Army Corps of Engineers in compliance with National Environmental Policy Act (NEPA) requirements and includes an analysis of the Duckabush Estuary Restoration site.

Further details can be found on the Duckabush Environmental Review webpage.
