Continued growth of HNTB Corporation’s operations in Southern California is driving the firm’s commitment to lease new office space in the Inland Empire. The new HNTB office is located at 3200 Guasti Road, in the city of Ontario in San Bernardino County.

HNTB, a national infrastructure firm celebrating more than a century of service to clients, opened the new office to better service key regional transportation clients, including the California Department of Transportation – District 8, San Bernardino Associated Governments, Riverside County Transportation Commission, and the City of Ontario, among others.

“Our commitment to Southern California in general, and to the Inland Empire in particular, is rooted in our decades-strong history with Caltrans and with the regional transportation agencies that are continuing to help shape future infrastructure for the benefit of residents and travelers,” said Khalil Saba, PE, HNTB Inland Empire area manager and vice president. “As these agencies continue to explore the implementation of alternative project delivery and tolling opportunities, HNTB is best suited to provide sound advice, unmatched resources and expertise, and unlimited support and lessons learned. HNTB is an industry leader in alternative project delivery services in design, program management and construction management for clients throughout California and across the nation.”

HNTB is a leading infrastructure solutions firm in the U.S. In California the firm has roots to the West since beginning work on Pasadena’s Arroyo Seco Bridge in 1914, the firm’s first year of operation, and has since been involved in some of the region’s most high-profile, complex infrastructure programs.

In Southern California, HNTB is currently providing toll facility program management and tolling technology services for the San Diego Association of Governments, the Transportation Corridor Agencies, Orange County Transportation Authority and Los Angeles County Metropolitan Transportation Authority.
