72nd Avenue at Dartmouth Road Intersection Improvement

KAI provided traffic analysis and design services to the City of Tigard for future improvements to the SW 72nd Avenue/SW Dartmouth Street intersection. With a number of pending development projects at the surrounding corners, the City commissioned a consultant team to develop preliminary and final design drawings so that the right-of-way needs and construction details could be determined and planned for in advance of the development. KAI developed future traffic forecasts, identified the recommended lane configurations and storage needs, provided recommendations for existing and future access locations, and prepared conceptual design drawings for recommended improvements. Working closely with City staff, the project engineering team, and developers of the adjacent properties, KAI prepared 95% design plans, specifications, and estimates for a new traffic signal installation and proposed signing/striping elements of the future project.
