Last night, a construction worker died after being hit by falling concrete while working in a tunnel under Grand Central Terminal. According to the Daily News, Michael O'Brien "was killed Thursday night in the collapse of a railroad tunnel deep under Park Ave., despite his father’s heroic efforts to save him... The young worker’s father, who was working alongside him, frantically tried to revive his son with CPR as workers rushed him through a network of tunnels to a waiting ambulance at E. 48th St. and Park Ave., the source said."

O'Brien, was a "sandhog" (think "urban miner") helping clear away bedrock for the big East Side Access project which will put a LIRR terminal under Grand Central. Apparently the tunnel collapsed around 7:30 p.m.

The MTA, which has suspended work at the site of the accident, issued a statement, "The Metropolitan Transportation Authority wishes to extend its deepest condolences to Mr. O’Brien’s family and his fellow workers."
