The State of Oregon’s first Urban Multi-Lane Roundabout (5,700 VPH Design Year Flow).
MTJ Engineering provided Capacity Analysis, Final Horizontal Design Recommendations, and Signing and Field Marking layout services to the City for this challenging and constrained urban re-construct project.
This project included provisions for bus rapid transit and a fifth leg serving access to residential neighborhoods. This roundabout opened in 2006.
