In late 2021, KPFF began studying a bicycle and pedestrian crossing over Highway 99W to support the City of Sherwood’s vision for a mixed-use, higher-density expansion and to connect existing neighborhoods to their newly opened high school across the highway. Less than four years later, the project opened in September 2025 as a landmark at the future center of Sherwood, OR.
This presentation will discuss how the signature structural design evolved from concept through construction. With a synergistic blend of pathway alignment/profile and structural type alternative studies, we developed a unique design at an efficient cost. Five simply supported, biaxially symmetrical truss spans are arranged into a dramatic undulating form totaling 900 feet on structure and 1/3 mile of new multi-use trails.
Our team leveraged BIM for the bridge design and for engagement with both the general public and prospective bidders. The bridge spans were erected during just three, 24-hour roadway closures. Through careful coordination between KPFF, the contractor, and subconsultants, the bridge opened on schedule and on budget.
