Wind gusts, especially on Interstate 10 in the Palm Springs area and on Interstate 15 in the Cajon Pass, frequently cause high profile vehicles to be diverted or stopped from using these highways when gusts reach 55 miles per hour. High wind areas are prevalent on all four of the interstates. Interstate 15 is heavily congested due to tourist travel to and from Nevada on the north and the transporting of commodities coming up through Mexico and San Diego in the south. Due to the high volume of large vehicles, truck lanes are becoming a necessity on major routes. Commercial distribution centers are rapidly growing in the Ontario/I-15 corridor, bringing not only additional jobs, but increased truck traffic.
