Transportation infrastructure depends on thoughtful planning, precise engineering, and innovative transportation engineering solutions that perform reliably over time. RPA is an expert in providing these reliable transportation solutions through roadway and highway designs that prioritize safety, operational efficiency, and long-term system performance. Our team helps clients across the Western United States address complex transportation challenges with designs that support freight movement, community connectivity, and multimodal mobility.

RPA’s transportation projects range from rural highways reconstruction to urban corridor improvements, multimodal facilities, freight routes, and complex interchange configurations. Each design is developed through detailed geometric evaluations, safety and traffic analysis, environmental and hydraulic review, and constructability considerations. This technical foundation ensures that improvements perform reliably under current conditions and adapt effectively to future needs.

Our streets and highway team supports clients through all phases of their transportation projects, including concept development, preliminary engineering, final design, permitting, and construction coordination. The team’s emphasis on accuracy, performance, and long-term value makes RPA a trusted partner for agencies seeking durable, maintainable, and cost-effective roadway and highway infrastructure.
