Worker trapped in Highway 4 construction accident

A construction worker was seriously injured Thursday evening after he became trapped in a piece of machinery and had to be extricated, according to a Contra Costa Fire Protection District fire official.

Firefighters were called to the center median of state Highway 4 near the Hillcrest Avenue offramp around 7:30 p.m. on a report of a worker trapped in a large auger, a tool for boring holes in the ground, according to Robert Marshall, a district spokesman.

Marshall did not know which construction equipment the auger was attached to. It took some time to extricate the worker, who was flown to John Muir Medical Center with a crushing injury in critical condition around 8:15 p.m., Marshall said.

There are currently two construction projects underway in the area where the injury occurred, including a highway widening project and a BART light rail extension. It is unclear on which project tonight’s accident occurred, Marshall said.
