Transportation projects are essential to public safety and a strong economy. Our team helps them move forward, no matter how challenging or complex – from highway construction to transit to waterways to airports, and all points in between.

SWCA has developed a transportation practice with highly skilled project managers supported by teams of scientists, planners and subject matter experts. From environmental planning to permitting and compliance, SWCA has the experience to help move transportation projects forward.  

SWCA has contracts that support departments of transportation and public works, port and airport authorities, regional transportation authorities and engineering firms throughout the country. In every case, wherever the project and however large or small, our single focus is to provide meaningful consulting, constructive ideas, and active project management to support your project through completion, efficiently and successfully.
