California State Route 73

The California State Route 73 ( SR 73 or 73 CA for short ) is an axis extending in a north-south direction State Route in the U.S. state of California. The 17.7 miles ( 28.5 km ) long road leads from Interstate 5 to Interstate 405 through the San Joaquin Hills. The northern section is known as the Corona del Mar Freeway. The southern part is called San Joaquin Hills Transportation Corridor and is a paid toll road. The State Route 73 runs parallel to the Pacific Coast Highway about.

The road is part of the California Freeway and Expressway System.


The California State Route 73 begins near Mission Viejo on Interstate 5, the so-called San Diego Freeway. The use of the southern section is provided free of charge and with several toll stations. In the next 12 miles ( 19 km) the road is nicknamed San Joaquin Hills Transportation Corridor. To the north it crosses the villages of Aliso Viejo and Laguna Niguel. In the city of Laguna Beach, the road finally meets the Laguna Canyon on the California State Route 133

In the further course, the CA 73 winds through the mountains of the San Joaquin Hills, extending partially over the territory of the Crystal Cove State Park. The following exits provide motorists easy access to the grounds of UC Irvine.

From Newport Beach California State Route 73 is also called the Corona del Mar Freeway. Residents can reach the areas of Newport Coast and Corona del Mar over the connection. The grounds of the John Wayne Airport (SNA ) is also tangent to the CA 73, which is overflown by aircraft taking off. Shortly after the junction with California State Route 55, it finally ends at Interstate 405 in Costa Mesa.


The California State Route 73 was built in the early 1960s. The road was to relieve the largely parallel Interstate 5, Interstate 405 and California State Route 1 (Pacific Coast Highway). The original route of the CA 73 followed the course of the MacArthur Boulevard in Corona del Mar, where they led to the Pacific Coast Highway.

The continuation of the route as a toll road was adopted by the San Joaquin Hills Transportation Corridor Agency ( TCA). As the road should run through the Laguna Canyon, there were violent civil protests. The southern section of the CA 73 in 1996 yet completed.
