Two students have died and several others were injured when a Houston Independent School District bus fell off the 610 South Loop on Tuesday morning.

The Houston Fire Department confirmed the student’s death to KHOU 11 News.

Houston TranStar reports the crash occurred at Telephone Road around 7 a.m.

Investigators with the Houston Police Department said a late-model Buick LeSabre on the left-hand side of the bus thought that a car was going to drift into their lane. The Buick then shift over into the school bus to avoid the other vehicle.

At that time, the school bus driver tried to avoid the Buick and over-correct and ended up falling off the overpass and onto the frontage road below.

Witnesses tell KHOU 11 News the bus nose-dived and then fell onto its side along the freeway embankment.

HISD said the bus was on the way to Furr High School when it crashed. One female student died at the scene while the bus driver and three students, two males and one female) were taken to the hospital in unknown condition.

District officials stated that preliminary indications are that all of those who survived the crash suffered injuries. Further information about their conditions is not available at this time.

Furr High School is also home to REACH Charter High School and it is unclear at this time whether the students attend Furr or REACH.

The accident is under investigation by Houston ISD Police and Houston PD.

“We are deeply saddened by this tragedy and the loss of one of our students,” said HISD Superintendent Terry Grier. “I ask all of the HISD community to join me in praying for all of those involved.”
