US 12 - Heron Street Bridge

Project news

A public meeting is scheduled for Wednesday, June 12 at the Rotary Log Pavilion in Aberdeen from 4:30 to 6:30 PM. Community members can drop in at their convenience to find out the results of the study, the final recommendation and the next steps.

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. 

Stay Informed

You can stay informed about the process to replace the US 12 Heron Street Bridge by checking back to this website often. We will be updating this site with information as it becomes available on upcoming meetings, proposed alternatives, and opportunities to comment.


US Highway 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 type and location that will move forward into design and construction.


The project is currently budgeted at $78.6 million. The finalized project funding will be determined following the results of the public process.

WSDOT is looking at four alternatives for replacing the US 12 Heron Street Bridge. Two of the alternatives replace the existing Heron Street Bridge. Cost estimates for these two alternatives are within available project funding limits. Two other alternatives replace both the Heron and Wishkah Street Bridges. Cost estimates for these two alternatives are more than the available project funding and would require additional funding.
