In 2014, the bridge spanning the Cedar River in Renton’s Riverview Park was removed due to seasonal flood damage and inadequate lateral support. PND provided permitting and design services and worked with the City of Renton to demolish and replace the old timber-supported pedestrian bridge over the Cedar River, a major salmon-bearing stream.

PND completed preliminary engineering, concept design, final design, geotechnical investigations, and demolition plans for the old bridge, which was demolished in August 2014. In conjunction with the bridge replacement, PND’s team also provided shoreline restoration design adjacent to the new bridge. Restoration efforts included planting native vegetation along the shoreline and designing and installing a new irrigation system. Services also included bid support and construction administration for the project.

Our team’s permitting efforts included working with the Washington Department of Natural Resources, the City of Renton, and local tribes to permit the new bridge. The new structure eliminates the previous three in-stream timber pile bents composed of creosote-treated timber and spans the 135-foot stream channel with a single-span arched truss bridge. The design includes a grated aluminum deck that allows sunlight penetration into the river below.  

PND would like to acknowledge our fantastic and highly skilled project design team who helped assure this project was successful: Hart Crowser; MacLeod Reckord; APS Survey & Mapping; and Applied Professional Services. PND would also like to acknowledge the work of Rodarte Construction, Inc. and Northwest Docks on the construction of this project.
