Infrastructure and Transportation

Parthenon has a comprehensive and diverse portfolio of projects encompassing streets, highways, bridges, and rail transportation. We have provided a range of services on some of the Nation’s largest and most complex infrastructure projects, resulting in improved commuting experiences for public transit passengers, motorists, and pedestrians. Our infrastructure work also includes smaller scale projects in local communities. Whether it is a multi-billion dollar construction project, or a local street drainage and utility upgrade, we put our full resources behind our work.


Parthenon’s team members have helped design and build transit and railroad systems throughout the West Coast. Our team members have worked with almost every major transit and rail agency in California. Our team of experienced transit and rail professionals has provided planning, design, construction management, program management and quality assurance/control management services for all modes of transportation including heavy rail, commuter rail, light rail, freight rail, passenger rail, intermodal facilities, and bus rapid transit.


Parthenon has a established reputation for delivering efficient and economic systems and is dedicated to providing high-quality professional services. We are proud to serve as planners, designers, quality managers, inspectors, design/builders, and program/construction managers for some of the largest transit and rail line extensions and rehabilitation programs in California.
