Cajon Pass - Road Transport

Road Transport

The Mojave Freeway (I-15) was built in 1969 over the Cajon Summit west of the Cajon Pass. It is a major route from Los Angeles and the Inland Empire to Las Vegas. The freeway runs above and parallel to an original stretch of historic Route 66 and 395. This stretch, which is now known as Cajon Boulevard, is a short but well-preserved fragment dating back to a rerouting and widening of the highway in the early 1950s. Only the southbound/westbound lanes are in use; the northbound/eastbound lanes and corresponding bridges are closed to through traffic. It is along this stretch of road, accessible via either the Kenwood Drive or Cleghorn Road exits that some of the best aforementioned trainspotting areas may be found.

The historic Summit Inn, off the Oak Hills exit at the summit of the pass, is a historic Route 66 diner and has been at its present location since 1952. Some maps may show the Cajon Pass as a feature on SR 138, which crosses I-15 south of the summit between West Cajon Valley and Summit Valley. The highest point on I-15 between Los Angeles and Victorville is thus sometimes identified as Cajon Summit. However, the entire area, including Cajon Summit, is often called Cajon Pass.
