Since 1988, CALTROP has helped to build infrastructure projects that get people where they need to go via bridges, highways, roadways, airports and rail transit. Our success has been achieved by offering high quality services in construction management, program / project management, risk management, construction inspection, public relations, quality assurance and other engineering service disciplines. Now, we are also helping people to communicate through our telecommunications division, which offers full design and construction services.

West County Connectors Project
