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.
About Stuart Finney
Stuart is a client-focused structural engineer with a willingness and ability to go beyond conventional solutions to achieve exceptional results. Since 1999, he has gained extensive engineering experience in both building and transportation structures and uses his accrued knowledge to anticipate potential issues before they occur and address them in the design. Stuart’s career features work with complexity and community importance, like the Barbara Walker Crossing, a pedestrian bridge in Portland’s Forest Park with an iconic design and people-driven function, and many seismically retrofitted vehicular bridges that help to make the Pacific Northwest safer. His engineering philosophy is to first concentrate on understanding the client’s goals, then allow those to guide the design.
About Nick Halsey
Nick began his journey with KPFF as an intern before being hired as an engineer in 2017 and earning a promotion to Associate in 2025. Over the years, he has contributed to an impressive array of projects spanning diverse market sectors, including the Block 216 Tower, the Benson Polytechnic High School historic modernization, and the signature Bicycle and Pedestrian Crossing of Highway 99W in the City of Sherwood. Nick's strengths as an engineer include finding creative solutions to complex problems, fostering collaboration and curiosity in project teams, and leveraging the use of BIM visualization tools throughout the design process. He thoughtfully details structural elements at every scale and enjoys designing projects with a holistic approach, prioritizing the experiential qualities of completed spaces.
