(CNN) A bus carrying Houston-area band students home from Disney World fell into a 50-foot ravine in Baldwin County, Alabama, early Tuesday morning, killing the driver, police said.

The crash and rescue effort closed down Interstate 10 in both directions near the Florida state line.

The students had just performed at Walt Disney World in Orlando and were on their way home to Texas on two buses when one of them crashed, Channelview Independent School District Superintendent Greg Ollis said.

Westbound lanes of I-10 were reopened by mid-afternoon, but eastbound lanes remained closed, according to the Alabama Department of Transportation.

The bus struck a bridge support when it landed in the ravine, and inspectors need to make sure the bridge is sound before reopening the interstate, Alabama State Trooper Capt. John Malone said.
