Featured Traffic & Transportation Engineering Projects

Station Road-Old Bethlehem Pike Roundabout

Richland Township, Bucks County, PA

Station Road, originally a state highway, was “turned back” to Richland Township so it could make changes to the intersection. This was the first roundabout to be constructed in the State of Pennsylvania and has reduced accidents significantly at this previously signalized intersection.

CEC designed the roundabout, with the approach roadway entering at a perpendicular to slow traffic within the circle. The center island’s 20-foot-wide concrete apron, which accommodates large vehicles, is treated with a product that simulates field stone to match the old Shaw homestead on the corner.
