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 (just south of I-405 in Irvine), and past this, SR 133 is a freeway (the Laguna Freeway) to I-5, and a tollway (part of the Eastern Transportation Corridor) to SR 241 near the Santa Ana Mountains.
SR 133 was constructed as a county road by the 1910s; the portion from I-405 to I-5 was upgraded to a freeway four decades later. The state canceled plans to extend the freeway segment south, and the southern part of the road remains an undivided highway. In 1998, most of the Eastern Transportation Corridor opened, and the connector between I-5 and SR 241 was designated as a toll extension of SR 133.
