Interregional Transportation Strategic Plan

ITSP Overview

The Interregional Transportation Strategic Plan (ITSP) is a statewide planning document that provides guidance  and prioritization through interregional corridor analysis for projects focused on improving travel access for people and goods on the State's Interregional Transportation System in a safe, equitable, sustainable, multi-modal manner. 

Caltrans prepared the first ITSP in 1998 in response to Senate Bill  45 (1997), which dedicates 25% of State Transportation Improvement Program (STIP) funding to interregional highway and passenger rail facilities.  The Caltrans controlled portion of the interregional improvement funds is programmed in the  Interregional Transportation Improvement Program (ITIP).  

The 2021 ITSP will include information on new Statewide policies, legislation, and funding, to reassess and update the purpose and objectives in order to:
