One construction worker was seriously injured and another suffered minor injuries after an industrial accident on the Burlington Skyway on Wednesday afternoon.

Police said the incident occurred at 1:30 p.m. at the Burlington Lift Bridge, near the Burlington Bay James N. Allan Skyway.

Three construction workers were trying to install an electrical cable about 35 metres above ground when it snapped, according to police.

One worker was knocked unconscious, police said.

A worker was taken to Hamilton General Hospital with serious and potentially life-threatening injuries. Another was taken to a local hospital, suffering minor injuries. A third worker did not have any injuries.

Initially, it was reported that a worker was dangling -- but police said this was not confirmed. It was also reported that a cable struck one of them. Police said it was not clear how the cable snapping impacted the workers.

The cables on the Lift Bridge were being replaced to update its aging infrastructure. The bridge was closed for investigation until just after 3 p.m.

The investigation is ongoing and has been turned over to the Ministry of Labour.
