as US 101 until 1964–1968. The portion of this highway from Woodland to Red Bluff roughly follows old US 99W. In California, the former western branch of Interstate 5 (the northern end of the spur into the Bay Area) connecting I-80 out of Vacaville to near Dunnigan, previously known as I-5W, was renamed I-505. Interstate 580 running between I-5 and I-80 was also once designated 5W; what is now I-5 (the stretch that runs through Sacramento) had been originally designated I-5E. The term "Golden State Highway" was the popular name for US 99, stretching from Mexico to Canada through the length of California. Since the construction of I-5, it has taken over the term "Golden State Freeway" from 99 south of the latter's southern terminus in Kern County. Los Angeles area The Golden State Freeway was proposed by the California Highway Commission in 1953. The proposal drew strong criticism from East Los Angeles residents as it would dissect and eliminate large residential and commercial areas of Boyle Heights and Hollenbeck Heights. The proposal also seemed to indicate a disregard for the ethnic Mexican American population of metropolitan Los Angeles. The "Boyle–Hollenbeck Anti–Golden State Freeway Committee" was formed for the purpose of blocking or rerouting the freeway. Then–Los Angeles City Council member Edward R. Roybal chaired that committee. Despite this opposition, the construction of the freeway went ahead. When this section was completed in 1956, the newspaper The Eastside Sun wrote the freeway led to the "eradication, obliteration, razing, moving, ripping asunder, demolishing of Eastside homes." The freeway between Orange County and Los Angeles was originally designed to have three lanes on each side. Due to high demand of cars, the freeway started undergoing major extensions and widening in the early 1990s in Orange County. Work from SR 91 north through the Los Angeles–Orange County line was completed in 2010. The improvements between the county line and the East Los Angeles Interchange are scheduled to be complete by 2023. Newhall Pass The original route went through the towns of Saugus and Newhall, and then crossed Newhall Pass (current route of SR 14, the Antelope Valley Freeway). In 1862, Beale's Cut was made in the construction of a toll wagon road. The by "slot" was dug with picks and shovels. That road would become part of the Midway Route. At the turn of the century, it was the most direct automobile route
