Washington Way Bridge

The Washington Way Bridge replacement project replaced an existing 66 foot wide, five-lane, timber-structure bridge that spans 160 feet, crossing over Lake Sacajawea in Longview’s historic Lake Sacajawea Park. GreenWorks worked with a team of engineers to provide architectural design input for a new concrete bridge that complements the historic character of the park and meets better safety needs with wider sidewalks and enhanced lighting. GreenWorks also provided architectural renderings of the proposed bridge design and additional graphic support for two public open houses to solicit public input. Architectural elements considered in the design of the bridge included railing design, layout of ornamental lighting, bridge materials and finishes, and bridge span and pier types. Planting design of the landscape adjacent to the new bridge included plant and tree species consistent within the context of Lake Sacajawea Park.
