State Route 22

California State Route 22

California 22 is a major east-west corridor through southern Los Angeles County and Orange County; the freeway segment is known as the Garden Grove Freeway. The state route begins at California 1 as a surface street, but quickly upgrades to a freeway when it interchanges with Studebaker Road. After a brief overlap with Interstate 405 southbound, California 22 continues east along a four to six-lane freeway. After passing through the Orange Crush interchange (Interstate 5 / California 57), California 22 ends at California 55 (Costa Mesa Freeway). The entire Garden Grove Freeway corridor between Interstate 405 and California 55 was completely reconstructed in the mid-2000s, beginning in 2004 and finishing in 2007.

Between 2004 and 2007, California 22 was reconstructed between Interstate 405 and California 55. Improvements included new through and auxiliary lanes, new high occupancy vehicle (carpool) lanes, and interchange modifications to improve efficiency and merging. Future improvements are planned to include new carpool lane connections with intersecting freeways.
