Edit 2: The Packard Plant bridge over East Grand Boulevard in Detroit collapsed around 3 p.m. Wednesday.
Joseph Kopietz, a member of Detroit-based Clark Hill's real estate group representing the 3.5 million-square-foot plant's owner, confirmed the collapse to Crain's Wednesday afternoon.
Earlier Wednesday, according to Kopietz, some on-site construction crews reported bricks were falling from the bridge that crosses Grand Boulevard as part of the sprawling, blighted factory campus on Detroit's east side.
