US 12 - Heron Street Bridge

Project News

After hearing from the public and working with local stakeholders on four design alternatives to remove and replace the aging US 12 Heron Street Bridge in Aberdeen, WSDOT has identified the preferred alternative as a two-lane, one-way span built in the same location along the existing alignment. The results of the previous online survey and public meeting revealed the response was overwhelmingly in favor of keeping the crossing in its same location.

Heron Street Bridge Alternative

    Replacing the bridge requires a number of permits, including one from the United States Coast Guard (USCG) requiring us to conduct a navigation impact report of the Wishkah River to determine how high the bridge needs to be for boats to safely travel under and if the bridge is fixed or opening. 


    US 12 is a major east-west transportation route through the City of Aberdeen with the Heron Street Bridge carrying 14,000 daily trips on average across the Wishkah River. This moveable span bridge was built in 1949 and is in need of major rehabilitation or replacement. WSDOT has begun preliminary design work to evaluate improving the existing bridge or determining the location and components of a new bridge crossing. 

    The End Result

    The end result of this public process will be a preferred recommendation for a new bridge location that will move forward into design and construction in 2024.


    The finalized project funding will be determined following the results of the public process.
