A tanker truck with a load of propane overturned Friday morning on the 60 Freeway in Jurupa Valley, snarling morning traffic and injuring at least one person.
The big rig and another vehicle collided at 5:25 a.m., causing the propane truck to overturn across two eastbound lanes of Valley Way, the California Highway Patrol said.
One patient was transported by ambulance to a hospital, according to a Riverside County Fire Department update.
A SigAlert was issued for the HOV lane and lanes 1 and 2 with traffic diverted off at Valley Way, the CHP said.
Riverside County firefighters remained on the scene until declaring it safe at 7:13 a.m. As of 8:40 a.m., crews said they would remain at the scene for an additional two to three hours to carry out vehicle recovery and leak mitigation processes.
