Costco Opens in Lee's Summit | Kansas City News

Costco is set to roll into Lee’s Summit this October, opening a massive 16,000-square-foot store at the busy intersection of MO-291 and US-50 — and city officials are bracing for traffic chaos that could rival last year’s Whataburger debut. But this isn’t just another big-box arrival — it’s the anchor tenant of the booming East Village development, which also includes Chick-Fil-A, Q39, and soon-to-come Starbucks and restaurants, all part of a larger plan that’s been cooking for a decade. The city’s long-term prep — from widened highways to rebuilt interchanges — meets Costco’s own high standards, which pushed for even more traffic flow than projected. Expect heavy congestion early on, but officials promise adaptive traffic signals and new roads as the area evolves. And hey, if you’re avoiding the gridlock? Sidewalks connect everything — even downtown. Listen in comfort:Get a discount on a Soli Pillow: http://solipillow.com/discount/dnn.
