HAMDEN, Conn. (AP) Hamden authorities say three workers who were injured after falling off an aerial lift at a construction site are expected to be OK.

Police say the three men were working at a site off State Street on Thursday afternoon when they fell off the lift. Officials say the workers were brought to Yale-New Haven Hospital to be treated for non-life threatening injuries.

The lift appeared to be about 20 feet off the ground.

Amtrak officials shut down a nearby track because of the accident, but said train service wasn't affected.

Officials with the Occupational Safety and Health Administration are looking into the accident.
