Travelers planning to use Interstate 15 near the Nevada/California state line, found themselves at a standstill as the major thoroughfare was closed in both directions south of the boundary, following an incident where a semi-truck hauling lithium-ion batteries caught fire. The shutdown extended from Afton Canyon to Basin roads after the San Bernardino County Fire Department responded to the blaze on northbound I-15 at mile marker 113, between Barstow and Baker, News 3 LV reported.
