Highway, Traffic & Rail Services

We have deep roots in highway, traffic and rail system planning and design. Our founder, John Clarkeson, advanced the idea that if our highways could be more than functional, they could be beautiful as well. Over the years, CHA has been nationally recognized for our role in designing some of America’s most scenic highways.

Our traffic professionals work with municipalities and departments of transportation to provide a wide range of traffic engineering and transportation planning services. CHA’s award-winning designs incorporate modern intelligent signaling systems capable of monitoring and responding to changing traffic flows in real time. Our certified traffic technicians and engineers work closely with our highway engineering group to provide thorough, high-quality solutions within our clients’ scheduling and budgetary requirements.

With regards to railroads, our engineers and planners have the unique ability to coordinate and expedite all phases of our clients’ projects including applications, approvals, permits, schedules, flagging, and the maintenance and protection of traffic. We focus on finding cost-effective solutions that make the most of scarce construction and rehabilitation dollars.
