California Transportation Commission - Trade Corridor Enhancement Program (TCEP)
The purpose of the Trade Corridor Enhancement Program is to provide funding for infrastructure improvements on federally designated Trade Corridors of National and Regional Significance, on California's portion of the National Highway Freight Network, as identified in California Freight Mobility Plan, and along other corridors that have a high volume of freight movement. The Trade Corridor Enhancement Program will also support the goals of the National Highway Freight Program, the California Freight Mobility Plan, and the guiding principles in the California Sustainable Freight Action Plan.
This statewide, competitive program will provide approximately $300 million per year in state funding and approximately $515 million in National Highway Freight Program funds, if the federal program continues under the next federal transportation act.
