Lane and Train Solution

In 2006, SBCAG and Caltrans approved 101 in Motion that was developed with local agencies, including the City of Santa Barbara, the County of Santa Barbara, and the City of Carpinteria. 101 in Motion determined that a long-term congestion relief strategy required a "Lane and Train" solution - new carpool lanes on Highway 101 and a peak-hour commuter train from Oxnard/Ventura to Santa Barbara/Goleta. 101 in Motion included other congestion relief strategies that are part of the Measure A Investment Plan passed by voters in 2008. Measure A is the 1/2-cent transportation sales tax that was approved by 80% of Santa County voters to fund improvements.
