Walk down rue St. Francois this week and you'll pass two different kinds of orange. Traffic cones mark a stretch where city crews have been working since August 28. A few blocks over, near Tower Park, new signage is going up for a pizza and Italian sandwich shop moving into the old train depot. Both are temporary in their own way. Only one of them is counting down to Labor Day.
Two Closures, One Calendar
The City of Florissant posted a notice near the end of August: work restrictions in Historic Old Town Florissant would run from Friday, August 28 through Monday, September 7. It's part of a roughly $2.6 million MSD Project Clear investment to upgrade wastewater sewers across the city, the kind of project that shows up as detours and tighter parking rather than a single ribbon-cutting moment.
That window happens to end on the one day of the year Old Town closes anyway. September 7 is the fourth and final leg of the Bommarito Audi West County Gateway Cup, a professional criterium series marking its 40th year. The races start in Lafayette Square on Friday, move through Francis Park and the Hill over the weekend, and finish in Old Town Florissant on Labor Day. For anyone living inside the historic district, that means roughly a week and a half where the neighborhood is under some form of restriction, first construction, then a full traffic shutdown, before either one lets up.
| Dates | What's Restricted | Why |
|---|---|---|
| Aug. 28 – Sept. 6, 2026 | MSD-related work zones in Historic Old Town Florissant | Part of a $2.6 million citywide wastewater sewer upgrade |
| Sept. 7, 2026, 6 a.m. – 6:30 p.m. | Entire race course closed to vehicles; all driveways onto the course closed | Final leg of the 40th Gateway Cup |
What Actually Shuts Down on Race Day
The two closures behave differently, which is worth knowing if you're planning around either one. The sewer work restricts. The race removes access entirely. Local coverage of the event confirms the whole race course through the historic district closes to vehicular traffic starting around 6 a.m. and doesn't reopen until roughly 6:30 p.m. on September 7. Every driveway exiting onto the course closes with it, and there's no parking allowed on the route itself, though emergency vehicles are exempted.
The course runs through what's technically a preservation district. Old Town Florissant's boundaries, roughly rue St. Francois, rue St. Ferdinand, rue St. Denis and Lafayette Street, cover about 156 city blocks and have sat on the National Register of Historic Places since the district's creation by local ordinance in 1969. The start and finish line sit across from City Hall at 955 St. Francois Street, with the race expo at the intersection of St. Francois and Boone. The current route finishes flat in front of City Hall, one mild climb, six turns.
Built Around the Neighborhood, Not Just Passing Through
None of this lands in Florissant by accident. Mike Weiss, who owns Big Shark Bicycle Company and organizes the Gateway Cup, has pointed out that the race earned Pro Road Tour status with USA Cycling and now closes out the national American Criterium Cup calendar. That status is part of why the series routes through recognizable neighborhoods rather than generic venues, and why organizers expect crowds as large as 50,000 spectators across the full four days, according to reporting from SoCalCycling on the race's 40th running.
Florissant's leg carries its own layer of local programming beyond the pro race. The Tour de Florissant Community Ride, backed by Power Up Training Center, offers 15-mile and 26-mile routes through the back roads of North St. Louis County, with on-site registration opening at 8 a.m. at the expo and wheels rolling at 9. Inside the Florissant Government Building, a separate fundraiser called Pedal in Place at the Race raises money for Parkinson's disease research, positioned right at the first turn so participants don't have to miss the action to take part.
New Storefronts Opening Into the Closure Window
The same blocks absorbing all of this have also been where Old Town's storefronts have been turning over. According to the city's economic development updates, a pizza and Italian sandwich shop from local residents and brothers Anthony and Mariano Castello has been slated to open in the train depot building at Tower Park, bringing pizza, subs and Italian market items to a space that had sat mostly empty. A yarn and craft store has also opened elsewhere in Old Town, with plans for crochet classes and stitch-and-meet nights. Neither business was built around a construction schedule or a bike race, but both are opening into the same compressed window, which means anyone launching a storefront in Old Town this fall is doing it with a construction zone on one side of the calendar and a full-day closure on the other.
The rest of the district hasn't slowed down waiting for either one to pass. Hendel's, the longtime restaurant on rue St. Denis, still had live music on its patio the Saturday before Labor Day, with local performer Jim Williams playing a set on August 29. The barricades and the patio string lights are running on the same eleven-day calendar, just pointed in opposite directions.
Wednesday Night Out Has Its Own Rhythm Running Alongside All of This
Florissant Old Town Partners describes its Wednesday Night Out street parties as a May-through-September tradition, the last Wednesday of every month. This year's July 29 edition doubled as the city's 240th anniversary celebration, folding a community birthday party into the regular street party rather than waiting for a separate occasion. That's the same recurring rule quietly running underneath everything else on this calendar, a Wednesday night party at the end of the month, race closures or not.
What's next on Old Town's calendar is the Florissant Fall Festival, set for the second Sunday of October, which lands on October 11 this year. Between now and then, the district moves from construction barricades to race barricades to, eventually, quiet blocks again, minus a couple of storefronts that used to sit empty.
What This Actually Means If You're Already Here
None of this changes anything about property values or how a house shows. It's simpler than that. If you're inside those 156 blocks, or walking a dog past Tower Park this week, the useful thing to know isn't only that a bike race is coming Monday. It's that the neighborhood has effectively been under some form of restriction since August 28, and Labor Day is the day that restriction goes from partial to total, right before the same streets settle back into hosting a new pizza counter, a yarn shop, and whatever the next nine months bring.
If Old Town Florissant already feels like home, The Winckowski Group keeps a close read on what's actually changing here, block by block, not because it moves listings, but because it's the kind of detail that tells you what living in this neighborhood feels like day to day. Reach out anytime you want a local's take on Florissant, whether that's this week's closures or the market whenever you're ready to talk.
