Mayer Brown is a recognized leader in applying PPP structures to major infrastructure assets in the United States and a preferred provider around the world. We have been counsel in path-breaking transactions involving long-term concessions and the development of highways and toll roads, rail networks, parking facilities, airports and ports.

We were named North American Infrastructure Law Firm of the Year by Infrastructure Investor in 2014-2016 and are ranked Band 1 in Chambers USA and Chambers Global 2020 for PPP projects. Chambers noted that we are unique among US market-leading infrastructure practices for the depth of our experience as government party counsel, sponsor’s counsel, lenders’ counsel and underwriters’ counsel, enabling us to understand and appreciate all perspectives of infrastructure transactions.

The core of our infrastructure practice consists of attorneys with extensive experience representing government entities on infrastructure and other transactional matters, including attorneys who have served in government in legal and policy roles. We have experience interfacing with the federal government on TIFIA and private-activity bond financing and regulatory matters related to infrastructure projects. We understand the unique issues facing governmental entities and the sensitivities of intergovernmental relations, which may be particularly complex at the federal, state and local levels with respect to individual projects.
