Many of the existing freeways in Southern California's Inland Empire were completed in the late 1970s.
In general, most of the higher paying jobs are located in Los Angeles and Orange County.
Although major freeway construction was finished years ago (except for the recent completion of SR 210 from Fontana to San Bernardino), growth in the region has strained the freeway system.
As a result, several major projects have recently been completed or are underway on freeways throughout the region.
Three major airports serve the Inland Empire: Ontario, Palm Springs, and San Bernardino.
