For thirty-seven summers, a Lee's Summit weekend had one gravitational center. You drove toward downtown, parked near Third Street, and everything you needed for a Saturday sat inside a ten-block radius. That shape is ending this month, and not gradually.
Between August 3 and August 28, the 291/50 interchange is opening two of the largest destination anchors this city has landed in a decade. In the same four-week window, Downtown Lee's Summit Main Street confirmed that its 2026 Downtown Days festival was the last one the organization will run. Two centers of gravity, one arriving and one being rebuilt from scratch, both closing on the same weekend calendar.
Four Weeks That Redraw The 291/50 Corner
The old story about that interchange was a shuttered Pfizer plant and a lot of pass-through traffic. The new story is 130 acres of construction on both sides of 291, anchored by two names that individually generate their own weekend traffic patterns.
| Date | What Opens | Where | Scale |
|---|---|---|---|
| Aug. 3, 2026 | Q39 | 240 SW Oldham Parkway (Oldham Village) | ~10,000 sq ft, 223 seats, patio for 200+ |
| Aug. 28, 2026 | Costco | 10 SE Oldham Pkwy (East Village) | 166,000 sq ft on ~24 acres, fuel facility |
| Late 2026 | Retail + apartments (Phase 1) | East Village | 64,000 sq ft new commercial, 320- and 250-unit residential |
The Chick-fil-A that opened at Oldham Village on February 26 was the appetizer. The developer behind both sides of 291, Overland Park's Drake Development, held a ceremonial groundbreaking in May and has told City Council that phase two involves demolishing the old Pfizer building outright. Whatever image residents carry of that corner from five years ago is no longer accurate to what it will look like at Thanksgiving.
What The Q39 Room Actually Is
Q39 in Oldham Village is not the Midtown location scaled down for the suburbs. It is the largest one the company has ever built, and it opens on Sunday, August 3.
The floor plan runs to nearly 10,000 square feet, which the Kansas City Star has reported as 223 seats plus a patio designed to hold more than 200. Inside is a butcher room, two bars, and a private dining area named the Rob Magee Room after Q39's late co-founder and pitmaster, capable of hosting about 40 guests. Executive chef Patrick Peluso is running the kitchen, and CEO Kelly Magee has confirmed reservations opened in July.
For residents, the practical change is that a chef-driven, sit-down barbecue option now exists inside the city limits with a real reservation system. The competition-plate menu comes over intact from the other locations, including the fire-roasted poblano cheddar cornbread and the six-person champion platter. What used to be a drive to Midtown or Overland Park for a table with white napkins and burnt ends is now a drive to Jefferson Crossing.
The Costco Question Downtown Merchants Are Quietly Asking
Costco confirmed the August 28 opening date through the City of Lee's Summit in July. As of that announcement, the steel frame was up and the parking lots were still being poured, but the company had already posted the full slate of jobs and the location was hiring.
A Costco representative told City Council the store will employ 150 to 200 workers, roughly half of them full-time, and described the format as a "destination site" that pulls customers from a wide geographic radius. That last part is the piece downtown merchants are watching. Costco does not compete with a hardware store on Third Street or a boutique on Douglas. What it does is reset which highway exit a Saturday errand run starts at.
"It's the blue ribbon of anchors. So where Costco goes, really good businesses, retail usually follows," Mayor Bill Baird told KCTV in December, calling the location the heart of the community.
Baird's read is the optimistic one. The tension he did not name is that the same corner is also getting an indoor recreation complex, with the Parks and Recreation board reviewing a $24.1 million construction bid for a roughly 100,000-square-foot facility with ten sports courts. Weekend youth basketball, a Costco run, a Q39 lunch, and a walking trail all sit inside the same development footprint. That is a full Saturday without ever crossing 291 westbound.
Downtown Just Lost Its Anchor Weekend. Here's What Actually Filled The Gap.
Downtown Days started in 1989 as Old Tyme Days, built by a group of business owners trying to reverse a declining commercial district. Nearly four decades later, in June, the board of Downtown Lee's Summit Main Street announced the 2026 festival was the last one. The stated reason was safety after disturbances during the Saturday evening of this year's event.
The important thing for residents is not the loss of one weekend in June. It is that the organization publicly committed to writing what it called "the next chapter" of downtown programming, and the pieces already on the ground are the ones that will carry that weight. A quick inventory of what is actually anchoring downtown right now:
- Green Street Market, the farmers market's new indoor home at 209 SE Green Street, running Saturdays and Wednesdays 8 a.m. to noon through October 31 with 70-plus vendors and retractable doors that turn the building indoor or outdoor depending on the weather.
- Third Street Social, the American restaurant inside Arnold Hall across from City Hall. The building itself is on the National Register of Historic Places and sits on the site where Harry Truman announced his candidacy for Eastern Judge of Jackson County Court.
- The Lee's Summit History Museum's "Remembering Lee's Summit" series, next held August 13 from 6:30 to 7:30 p.m. at Bridge Space, with additional dates October 8 and December 10.
- The Lee's Summit Farmers Market covered parking at 2nd and Green, which quietly solved the single most-cited complaint about a downtown Saturday.
None of that replaces a carnival Ferris wheel on Douglas Street. Taken together, though, it is a downtown that is programming smaller and more often instead of once a year and enormous. That is a different rhythm than the one residents have known since 1989.
A Saturday In August, Using Both Ends Of Town
The interesting move this month is not choosing between downtown and the 291/50 corner. It is stitching them together in a single day, which the geography actually supports. A working itinerary:
- 8:15 a.m. Green Street Market at 209 SE Green for produce and coffee, indoors if the August humidity is doing what August humidity does.
- 10:00 a.m. Walk to Arnold Hall's block for the National Register plaque, then a coffee refill on Third Street.
- 11:30 a.m. Drive east on U.S. 50 to Oldham Village. Q39 lunch. Reserve ahead through their site; the room seats 223 but is going to be full through Labor Day.
- 1:30 p.m. Costco run at 10 SE Oldham Pkwy, or skip the run and use the walking trails that Drake Development has built into the East Village site plan.
- 6:30 p.m. Back downtown for the second Wednesday or the August 13 Remembering Lee's Summit talk at Bridge Space.
The Amtrak station is still where it has always been, twenty minutes to Union Station, and the market has covered parking. What has changed is that the eastern half of the day now has a reason to exist that it did not have on July 4.
If you have owned a home in Lee's Summit for more than five years, the practical question this month is not whether the 291/50 corner is going to change property patterns. It already is. The question is what your block looks like when Costco opens the same week the school year starts and two downtown weekend routines have to find a new shape.
If you want a read on what these openings actually mean for the block you live on, Shawnna Murrell and the Murrell Homes team track this market by the corner, not by the ZIP code.
