Project Description

BNSF Washougal River Bridge Replacement

Camas, Washington

Start Date: February 2015
End Date: December 2017

oregon_eugeneHamilton was contracted for the replacement of an existing BNSF rail trestle that was built in 1911. The existing structure is being replaced with one 202-foot-long through-truss span, two through-plate girder spans and two 41-foot precast box girder approach spans (one on each end). In addition to the new
spans, the project includes construction of all new drilled shafts (eight total), cast-in-place concrete abutments, columns and caps on the structure. The complexity of the bridge replacement is escalated by the proximity to sensitive natural areas, construction adjacent to a WSDOT highway, in-water work, and tight right-of-way.
