FORT LAUDERDALE, Fla. — A woman seen dangling from a Florida bridge has been rescued by firefighters after she participated in a cancer walk earlier in the day.

City officials say the woman was walking across the New River railroad bridge in Fort Lauderdale on Saturday morning when it began to open. Witnesses called 911 to report that the woman was dangling 22 feet above the tracks with the bridge in the upright position.

Firefighters responded and helped rescue the woman using a 24-foot ladder. She was not injured.

The 55-year-old woman was wearing a pink shirt. She told authorities she had taken part in the breast cancer awareness walk earlier Saturday morning. It was not clear why she was on the bridge since pedestrians are not allowed on it.

The woman was not immediately identified.
