R&E prepared the plans, specifications, and estimate for channelization, pavement markings, traffic signing, illumination, storm, and water main for an urban single-lane roundabout at the SR20/Ship Harbor Blvd./Glasgow Way intersection. The project involved utility relocation coordination, roundabout evaluation, and roadway realignment to combine a four-legged intersection with a history of accidents and poor level of service into a single-lane roundabout. Located on SR20, the roundabout benefits the area with its traffic calming effects.
