Improving Traffic and Safety Through Roundabout Design

Challenge

The intersection of Peakview and Peoria in Centennial, Colorado, had many concerns: drivers and pedestrians had difficulty crossing, the pavement was damaged from heavy trucks, and traffic had increased due to commercial and industrial development.

Solution

The SEH team designed a roundabout that allowed vehicle traffic, including industrial semi-trucks, and pedestrians to safely travel through the intersection. The project also included water quality swales to help protect the sensitive Cherry Creek basin.
