Milwaukee Junction is based around the 1-75/1-94 interchange and roughly borders Woodward on the west, East Grand Boulevard/St. Aubin on the east, Holbrook Avenue on the north and East Warren Avenue on the south. The area is mainly industrial with big pockets of blight. “Milwaukee Junction was the Silicon Valley of its day; that day being about 100 years ago,” said Peter Cummings, the other principal of The Platform, while offering details about their purchase of the 100,000-square-foot building at 411 Piquette Ave.
