Summary
Snohomish County is seeking a Transfer Agreement with a qualified proposer to relocate, preserve and reuse the Granite Falls Bridge 102, which is owned by Snohomish County. Built in 1935, Granite Falls Bridge 102 is a 340' long, 20' wide structure located 1.5 miles northeast of downtown Granite Falls. The Granite Falls Bridge is believed to be historical and unique because of the 160' long arched Pratt truss that supports the bridge deck. A Pratt truss is a type of structural system commonly used in bridge construction. It is characterized by having diagonal members that slope down towards the center. The truss has eight 20' long panels with an overall rise in the arch of 35'. The bridge provides direct access to the Mount Baker/Snoqualmie National Forest via the Mountain Loop Highway which offers recreational opportunities and tourism to people across the state of Washington. The bridge is currently slated for replacement, with construction starting in 2028 and construction duration is two years. The existing bridge will remain until the new bridge is complete. It is anticipated that the existing bridge will be removed by the contractor in 2029. The bridge is eligible for the National Register of Historic Places for its engineering significance.
