The groundbreaking for what will be Detroit's tallest skyscraper on the site of the old Hudson's building was held Thursday morning. Bedrock Founder and Chairman Dan Gilbert was on hand with Detroit Mayor Mike Duggan, Michigan Lt. Gov. Brian Calley, and other guests. We're told the skyscraper will be around 800 feet tall. The city's current tallest building is the Renaissance Center at 727 feet tall.
