Clark Construction Delivers West Loop Skyscraper, Park Adjacent to Chicago Union Station

Chicago, IL - Clark Construction Group has reached substantial completion at 320 South Canal, Chicago’s newest 52-story office tower in the heart of the West Loop.  The milestone is a major step forward in the redevelopment of the area around Chicago Union Station, including the addition of the largest public park in the West Loop. Riverside Investment & Development Company developed the project. BMO Harris Bank is the anchor tenant.

Located directly south of the 1925 Union Station headhouse building, 320 South Canal features 1.5 million square-feet of Class A office space, a state-of-the-art fitness center, and a world-class conference facility. More than 8,000 feet of outdoor amenity spaces, including four private terraces, provide building tenants with sweeping views of downtown.

Designed by Goettsch Partners, the three-tiered building is oriented in the north-south direction along the east side of the 2.5-acre site. The east face of the building aligns with the property line, reinforcing the urban street wall defined by the historic station on the adjacent block.

Much of the site—approximately 1.5 acres—is set aside as public open space, featuring a large central lawn, pedestrian walkways and a variety of smaller spaces for outdoor activities. The office tower’s east and west façades showcase V-shaped structural transfers, which open up the ground floor, making the park an integral part of the building, and the building an extension of the park.

Connected to Union Station via an underground pedway, 320 South Canal offers a direct link to the Metra train concourse, Amtrak trains, and Loop Link CTA bus lines at the Union Station Transit Center. Located in close proximity to major expressways, the building also includes two levels of underground parking.

“Our goal was to maximize the benefits of this prime location,” says Tyler Lamkey, Senior Vice President at Riverside Investment & Development. “With beautiful views and unmatched access to transit, 320 South Canal delivers on all fronts.”

“Clark is proud to have delivered this new landmark in the West Loop”, said Dave Trolian, division CEO at Clark Construction. “With the addition of fifty stories of office space and a major public park, this project will bring new energy to the area surrounding Union Station.”

The office tower already began welcoming tenants in January 2022. The park will open to the public in June 2022.
