Things to Do in Lee's Summit This August 2026

On August 3, Q39 fired up its smokers at 240 SW Oldham Parkway. On August 28, Costco cuts the ribbon a few hundred yards away at 10 SE Oldham Pkwy. On that same Friday night, historic downtown will string up lights on Third Street for the "Dog Days of Summer" Fourth Fridays Art Walk. If you have lived in Lee's Summit longer than a year, you already sense what is happening. This month is the moment the city stops having one downtown and starts having two.
The thesis for August: the U.S. 50/291 corridor is not competing with Third Street. It is absorbing the errand-and-appetite half of your Saturday, which frees historic downtown to keep doing the slower thing it has always done best.
That is a real shift in how a weekend gets planned around here, and it deserves more than a listicle of openings.
Look at the last Friday of the month. Costco opens that morning at the southeast corner of U.S. 50 and Missouri 291, anchoring a 130-acre multi-use project called Oldham Village East that the City Council approved as a $416 million development at the intersection of those two highways. That afternoon, six miles west, Third Street shuts down for the "Dog Days of Summer" Fourth Fridays Art Walk on August 28th in Downtown Lee's Summit, with pop-ups from local artists and live music inside and outside of participating shops and restaurants.
Two grand openings, opposite geographies, same evening. If you live south of Chipman, you will feel the pull of both. The honest answer for most households is: warehouse run in the morning while the crowds are still figuring out the parking lot, then dinner and music on Third Street once the sun drops.
The corridor did not appear in August. It has been assembling itself in pieces since winter, which is why the ribbon-cuttings feel so compressed now.
Read that list twice. That is not a strip mall filling up. That is a second town center gathering itself around a highway interchange.
Here is the same Saturday in August, treated by geography instead of clock.
| Historic Downtown Saturday | Oldham Village Saturday | |
|---|---|---|
| Morning anchor | Green Street Market, 209 SE Green St., 8 a.m. to noon | Costco warehouse run + Chick-fil-A breakfast |
| What you bring home | Missouri-grown produce, local honey, cut flowers, handmade pasta | Bulk staples, gas, rotisserie chicken |
| Second stop | Coffee and a walk along Third Street | Errands at 50/291 that used to require a trip to Independence |
| Evening | Fourth Fridays Art Walk or a Howard Station Park concert | Sit-down dinner at Q39 with the garage doors open |
| What it costs in time | Half a day, on foot | An hour, in a car |
That is not a knock on either side. It is the point. The corridor gave residents back the time they used to burn driving I-470 for a warehouse membership. Historic downtown was never trying to be that. Now it does not have to pretend.
The Downtown Lee's Summit Farmers Market has the longest season of any unenclosed market in the region, running Wednesdays and Saturdays from the first Saturday in April through the last Saturday in November. It moved into the Green Street Market building at 209 SE Green Street, and it now features 70+ vendors offering fresh produce, eggs, meat, plants, honey, and baked goods inside a beautiful indoor market space with retractable doors.
Two rules keep it from drifting into a craft fair: only products grown in Missouri or within 150 miles of Lee's Summit are allowed at the Market, and an 80/20 rule means non-farmers can only make up 20 percent of the Market at any given time.
This is what a national warehouse retailer cannot reproduce, no matter how much square footage it commands. The market is not a shopping trip. It is a piece of civic infrastructure with a supply radius drawn on a map.
If you missed the news in June, read this slowly. Lee's Summit permanently canceled its Downtown Days festival after nearly four decades of hosting the annual event, with the Board of Directors of Downtown Lee's Summit Main Street announcing the 2026 festival would be its last. That was the first weekend in June anchor for a generation of families. It is not coming back.
What that means for August and the rest of the fall: the calendar is now carried by smaller, more frequent events instead of one big weekend. Worth putting on the fridge:
The center of gravity used to be one weekend a year. Now it is the last Friday of every month, plus the Market twice a week. That is a healthier calendar for a resident. Harder to miss, easier to fold into normal life.
For anyone who has been in Lee's Summit long enough to remember when Third Street emptied out at 5 p.m., here is the current playbook.
That is the local knowledge. It is not a list of places to go. It is a rhythm.
Two downtowns is a real change in the texture of daily life. It means shorter errands, longer evenings, and a calendar carried by monthly events instead of a single festival weekend. It also means historic Third Street can stop trying to be everything and lean harder into what it already does well: a walkable, low-speed, human-scaled block that treats the market and the Art Walk as its two lungs.
The corridor is not the enemy of the old downtown. It is the pressure valve. That is the story of August 2026 in Lee's Summit.
If you have been thinking about what any of this means for the value of a home closer to Third Street versus one closer to the 50/291 corridor, that is a longer conversation and one we have every week at Meredith Sterling and TribeKC Realty.
