Harrison's Columbus Day Week Belongs to Two Different Main Streets

On the morning of October 12, cars will start lining up along the small commercial strip that runs beside Silver Lake, not on Halstead Avenue, where most of Harrison's restaurants and shops sit. That's West Harrison Business District, and for one day it hosts the 46th annual It's Great to Live in Harrison Columbus Day Observance Car Show, followed that evening by the Rock Steady Band and fireworks at the West Harrison Firehouse on Lake Street. Two days later, on October 14, the town's other tradition takes over: a parade starting downtown and a festival at Ma Riis Park, the green space that sits between Town Hall and the Harrison Library.

If you've lived in Harrison for more than a year, you already know the town splits into pieces that don't always share a spotlight. What the 2026 calendar makes clear is how deliberately that split gets honored. This isn't one civic celebration with a parade route and a car show tacked on. It's two separate Main Streets each getting their own day, in a town that has spent nearly fifty years alternating which one goes first.

A Figure-Eight Town With Three Zip Codes

Harrison's shape on a map looks like a figure eight, split roughly where Interstate 287 and Interstate 684 cross near the center of town. The southern loop holds downtown Harrison, the commercial corridor along Halstead Avenue where Harrison Station sends commuters to Grand Central in about 45 minutes. The northern loop holds Purchase and West Harrison, the latter a genuinely boxed-in pocket bordered by a hill, a lake, and the interstate, with Lake Street as close to a single road in as you'll find in Westchester.

Both halves answer to the same mayor and town board, but they don't share a post office. Downtown Harrison, West Harrison, and Purchase each carry their own zip code and their own name, which is why the wooden signs at either end of Halstead Avenue read "Welcome to the Town-Village of Harrison, NY" rather than simply "Harrison." Even the fire protection is split: the combination Harrison Fire Department covers downtown, while West Harrison and Purchase each keep their own all-volunteer companies. When the fireworks go off at 95 Lake Street on October 12, they're launching from a firehouse downtown residents don't answer to and, most years, don't drive past.

That's the backdrop for why the Columbus Day week reads less like one town's celebration and more like two.

The Week, Laid Out

Read across that table and the pattern holds even in the details residents notice without thinking about them. The parade always starts at the corner of Thatcher and Halstead, a downtown intersection, and always ends at Ma Riis Park. The car show has run in the West Harrison Business District for decades, paired with the same firehouse fireworks. What moves is the order. In 2018, the fireworks fell on the Saturday before Columbus Day and the car show landed on the following Sunday, after the parade. In 2026, the car show and fireworks open the week on Columbus Day itself, and the downtown parade doesn't happen until two days later. The sequence shifts with where October 12 lands on the calendar. The commitment to giving each side its own full day does not.

Why West Harrison Is Building Its Own Momentum

The clearest evidence that this isn't just legacy scheduling is the newest addition to the week: the West Harrison Italian Heritage Festival, running along Lake Street on October 20 and now in its fourth year. A downtown-only civic calendar wouldn't need a second, standalone festival on the other side of town just six days after the main parade. West Harrison is building an event of its own, on its own street, timed to close out the same week rather than compete with it.

The dining scene backs this up. Osteria Padre Pio relocated to a larger space at 97 Lake Street, on the same strip as the car show and firehouse fireworks, and now offers valet parking for what the restaurant describes as a bigger, better version of itself. Downtown's Halstead Avenue corridor runs its own separate lineup: Fat Stu's All-American Burger at 323 Halstead, Piero's a few doors down at 123 Halstead, Trattoria Vivolo, and the corridor's newer arrivals. These aren't two ends of the same strip. They're two distinct dining identities, half a town apart, each with enough density to anchor an evening out without residents needing to cross the interstate divide.

Put the restaurant map next to the festival calendar and the takeaway sharpens: West Harrison isn't a smaller, quieter appendix to downtown Harrison. It's a second commercial district actively reinforcing its own identity, one Italian restaurant relocation and one new annual festival at a time.

What This Means for Your Week

If you're planning around the calendar rather than just reacting to road closures, here's how the two halves of town actually divide up:

• Expect West Harrison traffic first. The car show closes down the Business District for the day on October 12, and Lake Street will see fireworks crowds that evening. If you live near Silver Lake Park, plan parking accordingly.
• Downtown gets the parade route. Thatcher and Halstead will be closed the morning of October 14 for the parade lineup, with Ma Riis Park absorbing the festival crowd through the afternoon.
• The Veteran's Memorial Building hosts theater, not fireworks. "Stage Kiss" runs October 18 through 20 at 210 Halstead Ave, giving downtown residents an indoor option the same week Lake Street throws its Italian Heritage Festival.
• Passidomo Park pulls double duty. The West Harrison Pickleball Courts host a mixed doubles tournament on October 19, squeezed between the theater run and the Italian Heritage Festival, so expect a busy stretch on that side of town even without the headline events.
• The Police Open House is the one shared civic touchpoint. Held October 13 at 650 North Street, it sits geographically and calendar-wise between the two halves, a rare moment the week treats as belonging to the whole town rather than one side of it.

None of this requires choosing a side. Most Harrison households already move between both business districts without thinking about which zip code they're standing in. But the calendar this town builds for itself every October is a useful reminder that Harrison isn't one Main Street with a satellite neighborhood attached. It's two, each with its own firehouse, its own festival, and its own week to shine, and this year they happen to land eight days apart.
