Hazmat crews are using plastic shovels to scoop spilled sulfur at Yosemite. The CHP planned to open the highway by noon, but the cleanup is going slower than expected. They how hope to open the highway by 6 p.m. Monday.
A big rig driver was carrying the sulfur. The highly flammable chemical sparked several small fires. Hazmat crews and investigators with the EPA are on scene this morning. There is a quarantine zone within a half mile radius of the spill.
Many people coming out of the park Sunday night had to be detoured through Mariposa. Highway 41 is being blocked off in Fish Camp -- just north of Tenaya Lodge.
Authorities say the driver of the big rig kept going even after the spill.
Management at Tenaya Lodge says the hotel is near capacity. This is a busy week for Yosemite as entrance is free to the park through the weekend.
The driver of the big rig is in custody on suspicion of D.U.I., however its possible he was overcome with fumes from the spill.
