50 Years of Transportation Engineering Excellence

CHA's history is rooted in the success of large transportation projects, including the designs of many sections of the interstate highway system. From the beginning, the firm's leaders pioneered the creative, quality-oriented transportation engineering philosophies that have resulted in the prestigious reputation that CHA currently enjoys within the industry.

A Pioneer in Context-Sensitive Design

Creating transportation solutions that take community character into account is the foundation of our philosophy. Our founder, John Clarkeson, was quoted as saying, "If we are to do this work well, it must reflect the culture of the architect and the land use planner, and it must create a neighborhood, as well as a highway, that we can live with and be proud of for decades to come."

A Reputation for Quality

Many firms say they focus on quality. CHA was founded on the principle, and it remains an integral component of our culture. We know that providing quality service time after time is the only way to earn the trust of our clients. Quality doesn't happen by chance; it comes only from a commitment to our first priority: our clients' best interests.
