SR 22 begins at the intersection of 7th Street and Pacific Coast Highway (
State Route 1) in Long Beach. Then, 7th Street widens from an
expressway into a freeway just before crossing the
San Gabriel River (and with it, the Los Angeles/Orange County line). It then merges with the
San Diego Freeway (
Interstate 405) at the
Interstate 605 interchange and runs concurrently with it for approximately three miles before the two routes diverge in northeastern
Seal Beach. Thereafter, the Garden Grove Freeway travels mostly within the city of
Garden Grove or along its border with neighboring
Westminster. Just inside the Orange city limits, the freeway enters the infamously congested
Orange Crush interchange with the
Santa Ana and
Orange Freeways (
Interstate 5 and
State Route 57, respectively). It continues along the border of Orange and
Santa Ana for until terminating at the
Costa Mesa Freeway (
State Route 55). SR 22 is part of the
California Freeway and Expressway System, and is part of the
National Highway System, a network of highways that are considered essential to the country's economy, defense, and mobility by the
Federal Highway Administration. SR 22 from I-405 to SR 55 is known as the Garden Grove Freeway, as named by the State Highway Commission on October 22, 1957. An stretch of Route 22 is named the Garden Grove Police Officers Memorial Highway to honor police officers killed in the line of duty. ==History==
