A construction worker who was hit by a steel beam at the Twin Peaks Tunnel Project died on Friday.
Patrick Ricketts, a 51-year-old signal technician, was pinned underneath the beam at about 4:30 p.m. on Friday. According to the San Francisco Municipal Transportation Agency, nearby workers rushed to help Ricketts, who was transported to San Francisco General Hospital, where he died later that evening. Ricketts lived in the Colusa County town of Williams, 100 miles north of San Francisco.
MTA spokeswoman Erica Kato says Ricketts was employed by Oakland-based Shimmick Construction. Shimmick did not respond to a request for comment.
Work on the tunnel was suspended pending an investigation by San Francisco police and Cal/OSHA. The SFMTA said late Saturday that crews were cleared to resume work.
