Streeterville Is Going Up: 360 Chicago's $50M Expansion Puts the Neighborhood at the Heart of Chicago's 'WOW! Corridor'

By Socialhood News · Il/Chicago/Streeterville · April 1, 2026

Streeterville's skyline is about to get even more spectacular. The iconic 360 Chicago observation deck at 875 N. Michigan Avenue is slated for a sweeping $50 million expansion, cementing the neighborhood's role as a cornerstone of Chicago's ambitious new 'WOW! Corridor' — a cultural and economic spine that World Business Chicago is using to position the city as a global leader in immersive experiences and destination tourism.

The expansion is part of a larger citywide strategy that clusters world-class entertainment, retail, and cultural assets into must-visit destinations. According to World Business Chicago, the WOW! Corridor stretches across the city and includes transformative anchors like Navy Pier, Google's new Midwest headquarters at the Thompson Center, and the upcoming Bally's Casino — with 360 Chicago's Streeterville expansion standing as one of its most prominent lakefront jewels. The investment signals powerful confidence in Streeterville as a place where residents, visitors, and businesses all want to be.

For neighbors, this is big news — and a real point of neighborhood pride. A reimagined 360 Chicago means more foot traffic along Michigan Avenue, more vibrancy in the local economy, and a front-row seat to one of the most exciting urban investment stories in the country.
