"TUCSON, Ariz. — There is no timetable for reopening part of the main southern Arizona highway southeast of downtown Tucson, officials said Wednesday afternoon, a day after a deadly desert crash caused a hazardous material leak and forced evacuations nearby.
Less than 2 miles (3.2 kilometers) of Interstate 10 were still closed in both directions between Kolb and Rita roads after a truck tractor pulling a box trailer crashed Tuesday afternoon.
Residents within a half-mile (800 meters) of the crash initially were told to leave, and those within 1 mile (1.6 kilometers) were told to shelter in place after liquid nitric acid was determined to be leaking from the wreck, the Arizona Department of Public Safety said. The shelter-in-place order was extended to 3 miles (4.8 kilometers) Wednesday morning after more nitric acid was released as crews tried to remove the load, then reduced again to 1 mile by mid afternoon."
