Our History

Creating Order Since 1966

Founded in 1966 by Herbert Ayres and Bill Fehribach, A&F Engineering originally focused specifically on traffic engineering. As the industry’s challenges and needs evolved with time, A&F expanded into transportation design and site engineering. Though our projects’ nature and scope are vastly different than those early years, the fundamental values of professional expertise, critical thinking, and commitment to service remain unyielding.

We took nature’s solution to a human problem and perfected it.

We would be remiss not to mention our reverence and allegiance to the ant colony. Often overlooked is the fact that humans and ants are some of the only species that travel in two-way traffic patterns. The difference is, ants don’t get in traffic jams. We figured out why and used that to improve traffic flow in and around the state.

Community Involvement

The A&F team maintain both professional and personal lives of service: to our clients, to each other, and to our communities. The following organizations are passionately supported by members of our A&F team:
