State Route 133 (SR 133) is a state highway in the U.S. state of California, serving as an urban route in Orange County. It connects SR 1 in Laguna Beach through the San Joaquin Hills with several freeways in Irvine, ending at the SR 241, a toll road in the latter city. It is built as an expressway from SR 73 to Laguna Canyon Road, and past this, SR 133 is a freeway to I-5, and a tollway to SR 241 near the Santa Ana Mountains.

State Route 1 (SR 1) is a major north–south state highway that runs along most of the Pacific coastline of the U.S. state of California. At 656 miles (1,056 km), it is the longest state route in California, and the second-longest in the US after Montana Highway 200. SR 1 has several portions designated as either Pacific Coast Highway (PCH), Cabrillo Highway, Shoreline Highway, or Coast Highway. Its southern terminus is at Interstate 5 (I-5) near Dana Point in Orange County and its northern terminus is at U.S. Route 101 (US 101) near Leggett in Mendocino County. SR 1 also at times runs concurrently with US 101, most notably through a 54-mile (87 km) stretch in Ventura and Santa Barbara counties, and across the Golden Gate Bridge.
