If you’ve ever sat at the intersection of I-94 and I-35E at 5:15 PM on a Tuesday, you know the specific kind of existential dread that only St Paul MN traffic can provide. It's not just the cars. It’s the layout. St. Paul wasn’t built on a grid like Minneapolis; it was built on cow paths and dreams, resulting in a tangled web of one-way streets and sudden "dead ends" that actually just turn into steep hills.
You’re idling. The sky is that weird Minnesota grey. You're wondering why every single person in Ramsey County decided to take the Cretin Avenue exit at the exact same time as you.
Living here means developing a sixth sense for the "S-curves." It means knowing that during a Wild game at the Xcel Energy Center, downtown basically becomes a giant, expensive parking lot where nobody moves. If you're new to the area, or just a frustrated local, you need to understand that traffic here isn't a math problem. It’s a personality trait of the city.
The Reality of St Paul MN Traffic and the "Spaghetti Interchange"
Most people blame the volume of cars, but the real culprit is the infrastructure. The St Paul MN traffic patterns are dictated by the infamous "Spaghetti Interchange" where I-94 meets I-35E. This isn't a standard highway merge. It’s a high-stakes game of Tetris played at 60 miles per hour.
According to MnDOT (Minnesota Department of Transportation) data, this specific stretch handles upwards of 150,000 vehicles daily. When you have that many cars trying to weave across four lanes of traffic to hit the 10th Street exit or stay on 94 East, things get messy. Fast.
Honestly, the weave is the problem. You have drivers entering from the left while others are trying to exit on the right, creating a "cross-traffic" effect that slows everyone down to a crawl. It’s a design flaw from the 1960s that we’re still paying for today.
The Hidden Impact of the Mississippi River
St. Paul is a river city. That sounds romantic until you realize there are only a handful of ways to get across the water. Bridges are bottlenecks.
Whether it's the Robert Street Bridge, the Smith Avenue High Bridge, or the Ford Parkway, these crossings dictate your morning. If there’s a fender bender on the Lafayette Bridge (US-52), the entire southeast side of the city goes into a coma. There are no "side streets" when you're crossing a river. You're either on the bridge or you're stuck in the neighborhood.

One thing people often overlook is how the topography of the West Side—which is actually south of downtown, because St. Paul naming conventions are chaotic—forces traffic into very specific corridors. You can't just "cut through" when there’s a massive limestone bluff in your way.
Why Winter Changes Everything (And Not Just Because of Snow)
Snow is the obvious villain. But the real issue with winter St Paul MN traffic is the "black ice" effect on the hills. St. Paul is significantly hillier than its twin to the west.
Ramsey Hill. Summit Avenue. These aren't just pretty places to look at old mansions; they are treacherous slides in January. When the temperature hovers around 32 degrees, the moisture from the river freezes on the asphalt.
MnDOT spends millions on salt and brine, but they can't fight physics.
- Plow Priorities: The city prioritizes "A" and "B" routes. If you live on a side street, you might be stuck for 24 hours after a major dump.
- The "One-Side" Parking Rule: When a snow emergency is declared, parking becomes a nightmare. This narrows the streets. A two-lane road suddenly becomes a one-lane alleyway where you're praying you don't clip a side-mirror.
- Battery Deaths: Dead cars in the middle of Snelling Avenue cause more backups than actual accidents. Cold kills batteries, and a stalled car in the right lane during rush hour is a disaster.
The Secret Shortcuts That Don't Actually Work Anymore
We all have that one friend who swears by taking Shepard Road to avoid 94.
"Just take the river road," they say. "It’s faster."
They’re lying. Or at least, they’re outdated.

Shepard Road has become the "overflow valve" for the highway. It’s beautiful, sure. You get to see the barges and the trees. But between the stoplights at Davern and the commuters trying to reach the airport, it’s often just as slow as the interstate.
The same goes for University Avenue. Ever since the Green Line light rail was installed, University has become a stop-and-go nightmare. The train gets priority at many signals, meaning you’ll sit through three light cycles just to cross Lexinton. It’s great for public transit users, but for drivers, it’s a test of patience.
Construction: The Fifth Season
In Minnesota, we have four seasons: Winter, More Winter, Still Winter, and Road Construction.
In St. Paul, this usually means the "rethinking I-94" project. This is a massive, multi-year initiative by MnDOT to address the aging infrastructure between Minneapolis and St. Paul. They are looking at everything from adding lanes to creating "land bridges" that reconnect neighborhoods like Rondo, which were destroyed when the highway was originally built.
While the long-term goals are noble, the short-term reality is orange cones. Lots of them.
When a lane is closed on 94, the traffic bleeds into Selby Avenue and Grand Avenue. Suddenly, these quiet residential and shopping streets are filled with angry commuters trying to bypass the 20-minute delay. This creates a ripple effect. It's not just the highway that's slow; it's the whole city.

- The 2:00 PM Rule: If you can leave work at 2:00 PM, do it. By 3:15 PM, the school buses and the early commuters have already started the slog.
- Use the Apps, but Trust Your Eyes: Waze is great, but it sometimes suggests "shortcuts" through narrow residential alleys that are packed with delivery trucks. If the app says to turn onto a tiny street during a snowstorm, don't do it.
- The Ayd Mill Road Gamble: Ayd Mill Road is a strange, sunken highway that connects I-35E to the interior of the city. It’s fast, but it’s short. Use it to get to the Highland Park area, but be prepared for the bottleneck at the northern end where it just... stops.
- Reverse Commute Myth: There is no "reverse commute" in the Twin Cities anymore. People work in the suburbs (Eagan, Woodbury, Maplewood) just as much as they work downtown. Expect traffic in both directions.
The Cultural Impact of the Commute
It’s easy to talk about minutes and miles, but St Paul MN traffic affects how we live. It’s why people in St. Paul rarely "go over the river" to Minneapolis on a weeknight.
"It's too much of a haul," is a common refrain.
This geographical isolation has actually helped St. Paul keep its "small town" feel. People stick to their neighborhoods—Lowertown, Mac-Groveland, the West 7th corridor. We shop at our local Co-ops and eat at our local bistros because the thought of fighting the I-94 merge at 6:00 PM is enough to make anyone stay home.
Future Outlook: Will it Get Better?
Probably not. But it might get different.
The Metropolitan Council is heavily invested in BRT (Bus Rapid Transit) lines. The A Line on Snelling and the upcoming Gold Line are designed to take cars off the road. Will they? It depends on how much people value their personal space versus their time.
There's also the ongoing debate about the "3-lane" conversion on many city streets. To make things safer for pedestrians and cyclists, the city has been reducing four-lane roads to two lanes with a center turn lane (a "road diet"). While this reduces accidents, it definitely adds a few minutes to your drive.
Safety vs. Speed. St. Paul is choosing safety.
Actionable Strategies for Tomorrow's Drive
- Check the X (formerly Twitter) MnDOT accounts: They are surprisingly fast at reporting accidents.
- Avoid the "Lafayette Loop": If you see red on the map near the US-52/I-94 interchange, take the long way around via I-494. It’s more miles, but fewer headaches.
- Time the Lights: St. Paul’s downtown lights are timed for about 20 mph. If you gun it, you’ll just hit the next red. Relax.
- Park and Walk: If you’re going to a game or a concert, park 6-8 blocks away. You’ll spend 10 minutes walking, but you’ll save 45 minutes sitting in the parking ramp exit line.
- The "East Side" Secret: If you're heading east out of the city, use Highway 36 instead of I-94. It has more lights, but it rarely reaches the "standstill" status of the interstate.
Traffic in this city is a beast, but it's a predictable one. Once you learn the rhythms—the Friday afternoon exodus to "the cabin," the Tuesday morning fog delays, and the eternal mystery of the 7th Street light timing—you stop fighting it. You just put on a podcast, grab a Caribou Coffee, and accept that you’ll get there when St. Paul lets you.
