State Route 38 (California) State Route 38 is a state highway in California that connects the urban corridor of San Bernardino with the high country of the San Bernardino Mountains and the San Bernardino National Forest. The route serves as an arterial link between the Interstate 10/I-210 corridor and recreational destinations such as Angelus Oaks, Big Bear Lake, and access points for the San Gorgonio Wilderness. It is maintained by the California Department of Transportation and functions as both a commuter route and a scenic byway used by tourists, residents, and emergency services.
Route description
State Route 38 begins near downtown San Bernardino at an interchange with State Route 210 and runs eastward through the San Bernardino Mountains via the Highway 18/SR 330 corridor junctions before climbing through the canyon of the Santa Ana River. The highway traverses steep grades, hairpin turns, and alpine foothills as it passes through communities such as Forest Falls, Angelus Oaks, and the resort area near Big Bear City. Along its ascent the route parallels or crosses tributaries like Mill Creek and provides access to trailheads for peaks including San Gorgonio Mountain and Mount San Gorgonio Wilderness. SR 38 intersects with local arterials and national forest service roads that connect to Holcomb Valley and San Bernardino Peak trail systems before terminating at a mountain junction that links to county routes serving the eastern slope and basin communities.
History
The corridor that became SR 38 was originally contested mountain access used by early settlers, miners, and the Santa Fe Railway era supply lines. In the early 20th century, wagon roads and toll roads provided the first automotive access between San Bernardino and mountain communities like Big Bear City and Angelus Oaks. During the 1930s and postwar period, state investment in infrastructure under administrations influenced by projects tied to the New Deal and later state highway expansions formalized the route into the numbered California highway system. The designation evolved with regional planning by the California State Highway Commission and later Caltrans, reflecting changes in traffic patterns related to Interstate 10 construction and mountain recreation growth. Natural events including floods, landslides, and wildfires—such as notable incidents in the late 20th and early 21st centuries involving the Cedar Fire era regional impacts—have periodically required realignment, stabilization, and reconstruction, prompting engineering responses coordinated with agencies like the United States Forest Service and San Bernardino County Fire Department.
Major intersections
The major intersections along SR 38 include the western terminus at SR 210 and urban connectors in San Bernardino, junctions with county and state routes providing links to I-10, crossings near Crafton Hills access, and mountain junctions serving Forest Falls and Angelus Oaks. Key mountain junctions provide connections to forest service roads that lead to trailheads for San Gorgonio Wilderness and routes toward Big Bear Lake and Holcomb Valley. The eastern approaches intersect local county roads that continue toward the San Bernardino National Forest interior and evacuation routes used during emergency incidents coordinated with Cal OES.
Scenic and recreational features
SR 38 is noted for its scenic vistas overlooking the Inland Empire and valley basins, with viewpoints for the Santa Ana River canyon and access to recreational resources in the San Bernardino National Forest. The highway provides direct access to trailheads for San Gorgonio Mountain, Jenks Lake, and cross-country routes into the San Bernardino Peak area. Visitors use SR 38 to reach campgrounds administered by the United States Forest Service and recreational areas popular with hikers, anglers, and mountain bikers from the Los Angeles metropolitan area and Orange County. Seasonal features include fall foliage along deciduous riparian corridors and winter snowfields that can close sections of the road, influencing tourism patterns tied to regional destinations such as Big Bear Lake and historic mountain communities like Forest Falls.
Traffic and maintenance
Traffic volumes on SR 38 vary from urban commuter flows near San Bernardino to low-density recreational traffic in mountain segments; peak loads correspond with holiday weekends and seasonal recreation periods tied to visitors from Los Angeles County, Riverside County, and Orange County. Maintenance responsibilities fall to Caltrans District operations with coordination from San Bernardino County and federal partners for work within forest boundaries. Typical maintenance activities include pavement preservation, rockfall mitigation, bridge inspections tied to standards influenced by the Federal Highway Administration, and emergency repairs after landslides or wildfire-related erosion events such as those following the Hughes Fire (2007)-era impacts. Safety improvements have included guardrail upgrades, signage enhancements consistent with the MUTCD, and avalanche or snow-season management plans prepared with local authorities.
Future developments and projects
Planned and proposed projects for SR 38 focus on slope stabilization, improved drainage, and roadway resilience to climate-driven hazards that affect the San Bernardino Mountains corridor. Funding and planning efforts involve Caltrans, San Bernardino County Transportation Authority, and federal grant programs aimed at hazard mitigation and rural access improvements. Proposed initiatives include enhanced rockfall barriers, pavement rehabilitation, wildlife crossing studies linked to conservation planning with organizations such as the California Department of Fish and Wildlife, and multi-agency emergency access upgrades coordinated with Cal OES and the United States Forest Service. Future work aims to balance visitor access to recreational assets like San Gorgonio Wilderness and Big Bear Lake with long-term stewardship of the mountain environment.
