Chambers Creek Bridge Replacement
About the ProjectThe Chambers Creek Bridge serves as an essential roadway connection between the communities of Steilacoom and University Place. But after more than 70 years of use, the bridge shows signs of deterioration and impedes a regional project to restore salmon habitat.
Pierce County Surface Water Management is now exploring bridge replacement options as part of a greater effort to restore the Chambers Bay Estuary. The Chambers Creek Dam, which sits downstream of the bridge, is problematic because it blocks critical fish passage. A separate planning process consisting of multiple partnerships is underway to explore the dam's removal, but the exisiting bridge must first be replaced with a structure that can withstand any new hydraulic conditions.
Pierce County is finalizing a Type, Size and Location study. This analysis will outline bridge crossing alternatives and assess all potential impacts from removing and replacing the current structure. The County will have a completed Type, Size and Location Study by November 2023.
A Partnership: Restoration of the Chambers Bay Estuary
Forterra, Pierce County, the Puyallup Tribe of Indians, Squaxin Indian Tribe, Nisqually Indian Tribe and the South Puget Sound Salmon Enhancement Group, with support from the Town of Steilacoom and the City of University Place, are working together to restore the Chambers Bay Estuary.
The area has been heavily modified by industry since the late 1800’s, cutting off natural tidal systems and salmon habitat. The project will include the removal of a 100-year-old dam, replacement of a functionally obsolete bridge, relocation of utilities, enhanced public safety and park facilities, restoration of up to 180 acres of estuary and opening of three miles of Chambers Creek, two miles of Flett Creek and two and a half miles of Leach Creek to five species of salmon.
Funding for design and construction of the project has not been secured but preliminary planning and engineering is in progress.
Total Restoration Project Funding
To date, the funding for preliminary designs and necessary studies has been provided through a series of small grants and County Surface Water Management funds. Overall project restoration costs are expected to be between $40-$60 million over the life of the project. Project partners anticipate completing the final design in 2024, pending identification of viable fund sources.
Bridge Project Funding
Pierce County is currently reviewing state and federal infrastructure grants for long-term funding sources for this project.
