OKLAHOMA CITY - It took more than nine hours for crews to finish cleaning up a chemical spill in Southwest OKC.

Around 4:30 p.m. Saturday, the Oklahoma Highway Patrol closed the road at southbound I-44 and westbound I-240 following an accident in which over 1,200 gallons of highly corrosive organic peroxide spilled.

The roadway was re-opened around 2:00 a.m. Sunday.
