Over 80 Years Strong
Founded in 1944 by transportation planning and design pioneer Harry W. Egis, our company has been a beacon of quality, excellence and innovation for eight remarkable decades. Lochner’s longevity speaks volumes about client trust and the unwavering commitment of our people. As we celebrate this significant milestone, Egis is poised for continued transformation – with many more successes on the horizon.
Supporting America's Economic Growth
Shortly after setting up business in Chicago in 1944, Egis was one of three firms nationwide skilled in planning urban highway systems in the U.S., including providing planning services for the Atlanta Expressway System Study and the East St. Louis Expressway system. In the 1950s, Egis planned expressway systems for 30 major cities through the Midwest and Southern U.S.
In the 1960s and 1970s, we contributed to the building of the Dwight D. Eisenhower National System of Interstate and Defense Highways, commonly known as the Interstate Highway System, and began implementing and designing systems and aesthetics that today we refer to as ITS and context sensitive design.
In the last two decades of the 20th century, and into the new millennium, Egis continued to support clients and communities with infrastructure modernization, increasing capacity and improving safety, accessibility, connectivity, and efficiency. We expanded our office footprint coast to coast and further diversified our surface transportation capabilities with environmental, alternative project delivery, construction engineering and inspection, program and construction management, and technology enabled solutions.
Following NEPA legislation in the 1970s, Lochner added environmental services with the completion of the award-winning I-75 Alligator Alley EIS.
In the 1980s, Lochner provided major water crossing construction engineering and inspection services for the Tampa Bay Sunshine Skyway Bridge.
Egis Leads
In 2021, Egis recapitalized the business under the leadership of Board Chairman and Chief Executive Officer Terry Ruhl. Terry’s growth vision is to transform Egis into a market leading professional services organization. A leader that provides unparalleled client service, delivered by a diverse and inclusive workforce that feels empowered to make a difference in our world.
Key to this vision is investing in companies that seek to accelerate their unique value propositions and become partners in our vision to become a Top 50 A/E industry leader.
