The Challenge: We're Growing

Over the past 40 years, San Bernardino County’s population has tripled to 2.1 million people. This is expected to increase by more than 30 percent in 2035, and more than 60 percent by 2060; increasing the population to nearly 3.4 million people. That’s like adding the entire population of Phoenix, Arizona into the county. This trend is continuing with neighboring counties as well with Riverside County growing at a similar pace.

On the I-10 freeway, with this population growth, daily traffic is expected to increase to 350,000 vehicles by 2045. Increasing goods movement will also create heavier traffic conditions. For example, between 2003 and 2030, there will be a 75 percent increase in truck traffic on I-10 resulting in 23,000 trucks on the I-10 everyday.

On the I-15 freeway,  because it is the primary and often only choice for motorists to reach their destination, there is a tremendous amount of traffic along the corridor. Daily vehicle traffic averages about 223,000 and this number is expected to increase significantly during the coming decades as the population and economic standing of the High Desert will continue to grow. In addition, goods movement growth will also create heavier traffic conditions on I-15. Approximately 10 to 15 percent of total traffic consists of trucks, with up to 20,000 traveling on the corridor each day. Truck traffic is projected to continue growing by 2 to 2.5 percent per year.
