Overview

We’re innovators. Our attorneys have earned a reputation for helping clients deliver first-of-their-kind projects. We handled the first procurement under California's P3 law and developed the nation’s first availability payment contract. We also negotiated the first toll concession agreement in Texas history and the world’s first fully automated toll road using electronic transponders to collect tolls. Clients trust us to find a way forward.

Our attorneys have extensive global experience planning, procuring and financing award-winning transportation, public building, water and wastewater projects. Clients appreciate our experience leading signature engagements, not only for public agencies in the United States, but also for private enterprises and for public agencies in Canada, Australia and Asia.

We have spent more than 35 years guiding clients through large and complex project delivery. Along the way, we pioneered the nation’s use of availability payment, toll concession, pre-development, and design-build agreements. We continue to advance thought leadership in transportation policy and shape industry best practices by developing new approaches and ideas in procurement, contracting, and financing.

Infrastructure is the lifeblood of our communities and our country. We are proud to be on the leading edge, helping progressive agencies deliver projects that improve the quality of our transportation, water, education, health and safety systems.

Successes

Successes

  • Helping Secure a Sustainable, Local Water Supply for LA

    Nossaman is assisting the City of Los Angeles with the construction of the Advanced Water Purification Facility. The Project received WateReuse’s Excellence in Action award, recognizing its innovation and lasting impact.

  • Supporting Energy Development and Innovation

    We supported Google in its acquisition of Intersect Power for $4.75 billion in cash, plus the assumption of debt.

  • Helping Secure Innovative Financing for the Potrero Yard Modernization Project

    The SFMTA’s Potrero Yard, built in 1915, is being modernized to support a growing zero-emission bus fleet and improve working conditions. Nossaman secured financing for the $620 million project, achieving financial close in April 2026. Construction begins in early 2027, with project completion expected by 2030. This modernization will provide more reliable transit, reduce pollution and improve public health. The new four-story facility will increase bus capacity by 68%, enhance repair efficiency and offer sustainable infrastructure.

  • Improving Safety and Mobility on I-10 Calcasieu Bridge

    Nossaman is advising the Louisiana Department of Transportation and Development (LaDOTD) on the $2.1 billion project, which includes design, construction, financing, operations and maintenance of a new 6-lane bridge on I-10 crossing the Calcasieu River, development of a new toll system, modification and relocation of existing roadways and demolition and removal of the existing bridge. Currently, Nossaman is assisting with its implementation.

  • Breaking Ground on Convention Center Expansion

    Nossaman works closely with the City on its Convention Center Expansion and Modernization project, which reached a major milestone with its commercial close on September 30, 2025, and a groundbreaking the following day. The $2.6 billion project is anticipated to add up to 190,000 square feet of additional exhibit hall space, expand meeting room and multi-service space, and elevate the Convention Center into a global destination for conventions and events.

  • Reconnecting the San Gabriel Valley

    For generations, communities in the San Gabriel Valley have relied primarily on car travel to access jobs and higher education in Los Angeles and in the region, leading to heavy congestion on Interstates 10 and 210 – a problem worsened by the steadily growing population farther east. The success of Metro Gold Line Foothill Extension Construction Authority’s historic A-Line Expansion will now provide a new and alternative connection to the rest of Los Angeles County, including Long Beach and Downtown LA.

  • Securing Project Financing to Advance Express Lanes Expansion and Improve Traffic Flow Across Metro Atlanta

    SR 400 has transformed from a suburban connection into a highly congested corridor in the Atlanta metropolitan area as it experiences substantial population and job growth. We assisted the Georgia State Road and Tollway Authority with the financial close of the SR 400 Express Lanes Project to move forward with the design, financing construction, operations, maintenance and tolling of the Project under a 50-year concession agreement.
