California 126 Highway Guides

Between 1964 and 2002, California 126 used to continue east to meet California 14 via Magic Mountain Parkway and San Fernando Road, but that route was decommissioned. San Fernando Road (Old U.S. 99) was renamed by the city of Santa Clarita as three separate streets (from north to south): Railroad Avenue, Main Street, and Newhall Avenue. A freeway bypass was planned, but it was scuttled due to financial and community difficulties. The 8.5-mile, $245 million Cross Valley Connector (which includes Newhall Ranch Road and Golden Valley Road in Santa Clarita between the Interstate 5 / California 126 interchange and California 14) more or less substitutes for the proposed 126 freeway, although it was built to arterial/expressway standards. The Cross Valley Connector was completed through Santa Clarita on March 27, 2010.1
