Roadway systems have evolved to include multi-lane highways, freeways, toll roads and high-occupancy vehicle lanes. Our roadway professionals apply the latest industry standards and techniques – including 3-D, 4-D and even 5-D design – to the many elements of a roadway. We facilitate the design process by coordinating with our other in-house disciplines to adhere to federal, state and local design criteria. Our designs also consider the wider social, economic and environmental contexts; we employ innovative materials and construction techniques, and seek to preserve historic, scenic and environmental resources. From major bridges and interchanges to local streets, we design safe and efficient travel conditions.
