At SCJ Alliance, we’ve been at the forefront of designing and developing efficient and safe intersections, including roundabouts and signalized systems, for decades. With experience spanning more than 50 roundabout intersections and over 1000 signal systems across Washington, Oregon, and Alaska, our team excels in analyzing and delivering tailored solutions that balance traffic flow, safety, and cost-effectiveness.

Whether your community is deciding between a signalized intersection and a roundabout, our experts provide the data and design options needed to help it make informed decisions. We consider key factors such as wait times, safety considerations, and long-term maintenance costs to ensure that each intersection keeps cars moving efficiently and people safe without exceeding budget constraints.
