Traffic Engineering and Highway Design
Erdman Anthony’s highway experience began with survey, mapping, and design for the nation's fledgling interstate system in the 1950s. Today, we work with federal, state, and local governments to deliver projects throughout the eastern United States.
Our staff’s traffic engineering and highway design expertise translates to viable solutions that improve highway safety and capacity. Plus, we understand and respond to your project’s overall objectives, schedule requirements, budget constraints, community issues, environmental sensitivities, and more.
You can rely on Erdman Anthony to coordinate multiple activities and meet design schedules. We have worked extensively under open-end contracts for general service agreements involving the simultaneous advancement of multiple projects.
Once projects are underway, we can help manage them by providing design reviews, monitoring schedules, or handling other “on-call” services. And, as a firm providing construction services in multiple states, we have field-experienced staff on hand to review the constructability of our design.
We do all this for your project while also engaging on your behalf with outside stakeholders such as railroad owners, private ventures, environmental-review agencies, utility companies, and community groups.
For outstanding results – from assessment to implementation, rehab to replacement, bridges to rail, local roads to expressways – trust Erdman Anthony.
