Interregional Transportation Strategic Plan



The Interregional Transportation Strategic Plan (ITSP) is a California Department of Transportation (Caltrans) planning document that provides guidance for the identification and prioritization of interregional transportation projects identified on the State’s Interregional Transportation System. Caltrans prepared the first ITSP in 1998 in response to Senate Bill (SB) 45 passed in 1997, which altered the priorities and processes for programming and expenditure of State transportation funds. Those funding priorities have not changed; however, significant new statewide policies and goals have emerged since then. The Interregional Transportation Improvement Program is still required to fund improvements to the interregional transportation system and, specifically, to the 93 Interregional Road System (IRRS) routes and State-run intercity rail corridors. The ITSP remains the planning document that will be used in the identification and selection of projects for Interregional Transportation Improvement Program (ITIP) funding.
