San Joaquin region commuters make 120,000 daily trips west over the Altamont Pass to jobs located primarily in the Silicon Valley region.  To reduce traffic congestion and pollution caused by auto emissions, San Joaquin County implemented several transportation facilitation programs.  Measure K, a half cent sales tax for transportation, was approved by voters in 1990.  While some funds were earmarked for highway improvements, the number one project is Altamont passenger rail service.  Through Measure K the taxpayers of San Joaquin County have contributed more than $53 million in funding for the commuter rail service which has received national acclaim.  In 2006, $62 million of Measure K funds will be loaned to the State of California to be used for the widening of I-205.  San Joaquin County voters passed the 30-year extension of Measure K in 2006 and an estimated $3-to-5 billion will be available to support transporation projects, including highway improvements, through 2041.
