  • More exciting news! Harper Houf Peterson Righellis Inc.received an Honor Award for the 2025 ACEC Oregon Engineering Excellence for Tualatin-Sherwood Road/Roy Rodgers Road in Washington County! This project was selected for Washington County’s Major Streets Transportation Improvement Program (MSTIP) funding to provide improvements to the local and regional transportation network. In addition to localized capacity and safety improvements, the project was tasked with enhancing one of the key east-west arterials identified in the I-5 to 99W Connector Study. The design team’s challenge was to improve the corridor and serve this regional role without impacting local business access or creating a barrier for bicycles and pedestrians.  During the alternatives analysis, a major challenge was determining how to improve traffic efficiency through this high-volume, high-freight corridor. Conventional wisdom is to widen the road and increase the number of lanes. However, the preferred alternative reduced the overall width of the roadway, but increased efficiency by reducing signals and access points, and improving the lane geometry to eliminate trap lanes and other lane changes. Implementing these changes, which included removing a traffic signal to two major shopping centers, required a high level of commitment by the agencies to work with all transportation partners and the adjacent business owners. The result is an efficient transportation system which serves as both a regional traffic and freight corridor, providing multi-modal access and a local connection for the community. Thanks to Washington County for allowing us to work on this major roadway design! A big thanks to our project team DKS Associates, NV5 and Archaeological Investigations Northwest. https://lnkd.in/g2ysNqGk

  • Harper Houf Peterson Righellis Inc. received an Honor Award for the 2025 ACEC Oregon Engineering Excellence for the Linwood Avenue Corridor Improvements project in the City of Milwaukie! The Complete Street design balances the safety and access for all modes of travel and creates a welcoming environment of all users. The benefits to the community are substantial. By providing safe and accessible routes for pedestrians and cyclists, the project promotes healthier lifestyles and reduces the reliance on motor vehicles. It also enhances the connectivity between neighborhoods, making it easier for residents to reach local schools, parks, and other amenities. Thanks to Clackamas County and the City of Milwaukie for allowing our team to design this corridor.

  • SE 129th Avenue/King Road Roundabout | Happy Valley, OR Harper Houf Peterson Righellis Inc. designed a new compact roundabout at the intersection of SE 129th Avenue and SE King Road for the City of Happy Valley, Oregon. The work included undergrounding overhead utilities as well as the construction of the new roundabout. Prior to construction, the intersection was a 3 lane stop controlled intersection that had long delays during peak traffic hours. HHPR and Team worked closely with the City of Happy Valley and Clackamas Fire District to ensure that emergency vehicles from the fire station could be accommodated within the area, which was limited by existing buildings and development. The project has been well received by the public and is working to provide a safe intersection that meets the traffic demands of the area. Thanks to DKS Associates for providing Traffic Engineering services for the project.

  • Western Avenue Improvements | City of Beaverton, OR The Western Avenue Improvement project realized the vision of the City of Beaverton's West Five Development strategy by improving the Western Avenue corridor from an existing four-lane roadway section with intermittent sidewalks and no bike lanes to a three-lane roadway section with protected bicycle facilities and separated sidewalks. These improvements were one of the core strategies of the West Five Plan to support and foster growth of the industrial businesses along the corridor. Approximately one mile of roadway was improved, with bicycle and pedestrian facilities, two new traffic signals, a new railroad crossing, stormwater management facilities, utility undergrounding, and rehabilitation and replacement of storm sewer and sanitary sewer facilities along the corridor. The project also included installation of a 48” water line as part of the Willamette Water Supply Program. HHPR provided project management, public involvement, civil engineering, structural engineering, land use planning, natural resources, landscape architecture, construction inspection, and construction administration support services for this corridor project! Thank you City of Beaverton for allowing us to design this corridor project!
