union station

Sterling Bay is proposing a skyscraper connected to Union Station that would become one of the city's tallest, as the Chicago-based developer vies for the assignment to redevelop real estate owned by Amtrak.

The firm wants to build a 958-foot-tall, 2 million-square-foot office tower alongside the massive transit facility in the West Loop and is already in talks with tenants large enough to kick off the project, Sterling Bay Managing Director Andy Gloor said today.
