Providing construction support services for the transportation industry is the cornerstone of CALTROP. For over 20 years, we have developed innovative solutions for public and private clients building roads, highways and bridges. We are especially attuned to state departments of transportation, and work closely with them through our array of services – construction management, program / project management, inspection, specialty inspection, risk management and public relations.

CALTROP has accomplished an impressive portfolio of work on some the most important transportation projects since 1988. But whether it is the San Francisco-Oakland Bay Bridge, or the I-210/SR-60/SR-91, or the I-5 Gateway project or a roadway project in your municipality, on projects small to large, and simple to complex, we bring cost-saving creativity, state-of-the-art technical knowledge, and project delivery expertise. CALTROP’s transportation experts are committed to quality, sustainability, safety and protecting the public's investment.
