Streamlining Traffic With a Tight Diamond Interchange and Three Roundabouts

Challenge

A highly-traveled urban interchange had to be replaced and needed to accommodate more modes of transportation.

Solution

The multidisciplined SEH team designed a tight diamond interchange and three roundabouts for traffic control. Improvements also included pedestrian and bicycle paths, reconfiguration of local frontage roads, landscaping, lighting, aesthetic treatments and public art.
