TPD has provided transportation planning and engineering services for the design, construction, and inspection of several roundabouts throughout the Mid-Atlantic region.

Through this experience, TPD has coordinated complex issues for the design and construction of various roundabouts, including traffic counts and capacity analysis, conceptual design of the roundabout, preparation of fully engineered Final Design Plans, Roundabout Lighting Designs, preparation of Right-Of-Way Dedication Plans and legal descriptions, and presentations to Township Traffic Safety Committee, Supervisors and Public.

Notable achievements that accompany the current project experience include the construction of the first Pennsylvania roundabout on a State Numbered Route and the design of the first privately permitted multi-lane roundabout in Pennsylvania.
