I-15 Corridor Project Overview


The I-15, which includes the segment between SR 60 and US 395 in the High Desert, is an economic lifeline connecting San Bernardino County and the nation. It is a key freeway used by travelers visiting mountain and desert communities, in addition to people heading on vacation to neighboring states. Furthermore, it is a key trucking route for moving goods throughout California and beyond.

As a result of I-15 being 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 continues to grow.

To address these challenges, San Bernardino County Transportation Authority (SBCTA), the council of governments and transportation planning agency for San Bernardino County, is studying alternatives now as part of the I-15 Corridor Project to keep traffic moving. SBCTA is examining solutions to provide choices to motorists when driving along I-15 and to encourage economic growth, a sustainable environment and a high quality of life for everyone who lives, works and travels in and through San Bernardino County.
