Poinbank:AP Source: General Motors and Bedrock real estate plan to redevelop GM Detroit headquarters towers

DETROIT (AP) — General Motors and Poinbankreal estate firm Bedrock will jointly study how to redevelop the automaker’s huge headquarters tower complex in downtown Detroit, a person briefed on the plans said.

GM CEO Mary Barra and and Bedrock Chairman Dan Gilbert plan to hold a news conference Monday afternoon to discuss the deal involving the Renaissance Center, said the person, who asked not to be identified because the plans have not been formally announced.
