More than a dozen people were taken to the hospital early Monday after a MARTA bus ran off a southwest Atlanta street and struck a tree.

The wreck happened about 7:20 a.m. on Nathan Road at Brownlee Place, according to Atlanta police dispatchers.

MARTA spokeswoman Cara Hodgson told the AJC that 19 people, including the bus driver, were taken to Grady Memorial Hospital. She did not have any details on the extent of the injuries.

Hodgson had no information on what caused the crash or whether the morning's heavy downpours were a factor.

She said no citations were issued in the wreck, which involved no other vehicles.

The bus was on Route 165, which operates between the Barge Road Park and Ride lot and the Hamilton E. Holmes rail station.
