An 80-year-old man struck by a bus weeks ago on the West Side has filed a lawsuit against the Chicago Transit Authority.

The lawsuit alleges the bus driver was negligent when they failed to stop for the man crossing the street Nov. 16 near Madison Street and Pulaski Road in the West Garfield Park neighborhood.

A police report claims the man was crossing the street outside of a crosswalk when he was struck by a bus turning west onto Madison from Pulaski, according to Chicago police.

He was taken to Stroger Hospital in serious condition at the time, police said.

Timothy Cavanagh, the man’s attorney, said the man’s leg was amputated as a result of the crash and that the man remained hospitalized at Stroger on Thursday.

The man’s lawsuit rejects the police narrative and insists he was in a crosswalk and that the bus driver failed to yield the right-of-way and slow down.

The man is seeking more than $50,000 in damages.

A CTA spokesman declined to comment Thursday, stating that it was the agency’s policy not to comment on pending litigation.
