An estuary restoration project’s rail bridge that Hanson is working on is in progress in Washington state.
Pile driving has started at Snohomish County’s Meadowdale Beach Park as part of the restoration of the 1.3-acre area that will deliver a rearing habitat between Lunds Gulch Creek and Puget Sound for chinook, chum and coho salmon and cutthroat trout. The Puget Sound chinook is a threatened species under the U.S. Endangered Species Act. A 6-foot-wide culvert and 128 linear feet of railroad embankment will be replaced with a five-span rail bridge with a 100-foot opening, giving juvenile salmon access to a pocket estuary where they can grow.
A crew conducts pile driving May 18 for the Meadowdale Beach Park estuary restoration project in Snohomish County, Washington.
The site north of Lynnwood was last an estuary in the late 1800s, before the railroad was constructed.
Hanson is providing bridge design and construction management services for this project, which will cost an estimated $16 million.
