Grays River Covered Bridge

The Grays River Covered Bridge is a one-lane wooden covered bridge over the Grays River in western Wahkiakum County, Washington. The bridge is listed on the National Register of Historic Places and is the only covered bridge still in use by the public in Washington State. The bridge rests as the centerpiece of the Alhberg Park in Wahkiakum County. The park hosts the Grays River Covered Bridge Festival every two years.


The bridge itself was built in 1905 by dairy farmer Hans P. Ahlberg in order to allow horse and wagon traffic across the river. Ahlberg's farm spanned both sides of the river. Ahlberg contracted with the company 'Ferguson & Huston' of Astoria Oregon who drew up the plans. The bridge was covered three years later, in 1908. The roof of the covered bridge was originally built of "board and batten cedar siding with a capped tin roof" The reason for the covering was to preserve the expensive wooden trusses from the ravages of the area rains.

The Grays River Covered Bridge received a major restoration in 1988. In disrepair and at risk of being torn down, the residents of Grays River and Wahkiakum County, Washington worked to raise funds for restoration. Reconstruction was completed by Dulin Construction of Centralia, Washington, for a cost of $295,980.00. On September 30, 1989, with the repairs completed, the bridge was rededicated to public use. Author, Granger The National Grange of the Order of Patrons of Husbandry, and Grays River Resident Robert Michael Pyle served as Master of Ceremonies for the event.
