Spanning three city blocks in downtown Salt Lake City, the $1.5 billion commercial area opened in 2012 and blends high-end shopping with business offices, residential units, and tree-lined walkways centered on a simulated creek complete with fountains. The open-air architecture fills the walkways with natural light during the day and is well illuminated at night. A 15,000-square-foot retractable roof provides part of the area with some protection from precipitation. The mall includes more than 500,000 square feet of retail space anchored by a Nordstrom and Macy’s, and surrounded by more than 100 specialty shops.
