The San Bernardino Mountain Area stretches from the Los Angeles County Line on the west to the Lucerne Valley on the east. The communities of San Bernardino County within the study area include Wrightwood, Crestline, Blue Jay, Lake Arrowhead, Running Springs, Green Valley Lake, Arrowbear and Big Bear City as well as the City of Big Bear Lake.
The primary access roadways of SR-18, SR-330, and SR-38 experience unique traffic patterns associated with visitors to the area. While the full time population and associated employment are relatively low, substantial increases occur during the peak winter and summer seasons. As a result, traffic congestion occurs for extended periods as visitors and associated additional employees attempt to access the San Bernardino Mountain communities.
Traffic congestion can also discourage would-be visitors, hindering the local economy in the San Bernardino Mountains. All relevant parties including the County of San Bernardino, the City of Big Bear Lake, Caltrans, SANBAG, SCAG, and the California Highway Patrol are committed to finding solutions to improve access to the study area by identifying, analyzing, and mitigating congested intersections and roadway segments.
