You’ve probably noticed it. That weird feeling when you're merging onto I-235 at 7:45 AM and the skyline looks gorgeous, but the brake lights in front of you are definitely not. Honestly, for a city that used to brag about "fifteen minutes to anywhere," Des Moines is growing up. And with that growth comes the reality of real-city congestion.
It’s not Los Angeles. We aren't gridlocked for three hours. But Des Moines Iowa traffic has shifted from a minor annoyance to something you actually have to plan around. If you’re living in Waukee and working downtown, or commuting from Ankeny to West Des Moines, the "secret" backroads aren't so secret anymore.
The Southwest Mixmaster is Basically a Giant Construction Zone
If you want to know what’s really eating your time, look at the Southwest Mixmaster. This is where I-35, I-80, and I-235 all try to occupy the same space at once. It’s been a headache for decades because the original 1960s design just wasn’t built for 2026 volume.

Right now, the Iowa DOT is deep into a multi-year modernization. We’re talking flyover ramps and adding lanes to eliminate those terrifying "short merges" where you have about three seconds to get over three lanes of traffic. Specifically, the work around the University Avenue and Hickman Road interchanges has been a mess. The Northbound I-35/Eastbound I-80 entrance ramp at University was supposed to be open by now, but inclement weather pushed things back. As of mid-January 2026, the DOT is eyeing April or May for that ramp to finally breathe again, once the Walnut Creek bridge is finished.
Don't expect the orange barrels to vanish overnight. This whole Southwest Mixmaster project is a beast that runs through 2029. It’s a $114.5 million bet on the future, but for now, it just means you'll be spending more quality time with your favorite podcast.
Why 18.8 Minutes is a Total Lie (Sometimes)
Statistically, the average one-way commute in Des Moines is around 18.8 minutes. That sounds great on paper. Compared to the national average of 27.2 minutes, we’re living the dream. But stats are funny like that. They don't account for the "frozen precipitation" mornings where I-235 turns into a skating rink.
- Rush Hour Peaks: The heavy lifting happens between 6:30 AM and 8:30 AM.
- The 7:00 AM Surge: Roughly 16,000 people hit the pavement at this exact time.
- The Travel Time Index: Most major roads here have an index of 1.5 or lower. This basically means a trip that should take 10 minutes takes 15 during peak hours. Not a tragedy, but annoying.
The real trouble is the "Planning Time Index." Because of the construction and the unpredictability of Iowa winters, local experts suggest you actually need to plan for 1.7 times the free-flow travel time to be on time. So, that 20-minute drive? Better leave 34 minutes early if you have a meeting you can't miss.

The Broadway Avenue and West Side Bottlenecks
It’s not just the big interstates. Local projects are popping up everywhere, especially as Polk County tries to fix some long-standing issues. The Broadway Avenue Improvement Project is a big one. They’re literally lowering the road under I-235 to get rid of "low clearance" issues for trucks. If you live near NE 38th or 46th, you’re dealing with new roundabouts and signal upgrades that should be wrapping up later in 2026.
Over in West Des Moines, the expansion is relentless. Ashworth Road is getting reconstructed from 19th to 23rd starting this spring. Plus, the widening of Mills Civic Parkway (from South 81st to 88th) is turning a 2-lane rural feel into a 6-lane divided monster. It's necessary because the development out toward the Grand Prairie Parkway is exploding, but it makes that Saturday trip to Jordan Creek a lot more complicated.
Surviving the 2026 Des Moines Commute
Look, the reality of Des Moines Iowa traffic is that we're in a "growing pains" phase. The city is getting bigger, and the infrastructure is playing catch-up. To keep your sanity, there are a few things you should actually do.
First, quit guessing. The Iowa 511 app is actually decent these days. It gives you the "Future Construction" layer which shows you what's going to be closed next Tuesday, not just what’s closed now. If you're heading toward the Mixmaster, check the DSMInterstates Facebook page. They post updates that are way more specific than the evening news.
Second, understand the "Mixmaster Alternative." If the I-35/80/235 junction is a sea of red on your GPS, 100th Street and NW Urbandale Drive are the standard detours for a reason. They get crowded, but they keep moving.

Actionable Next Steps for Des Moines Drivers:
- Check the 511ia.org cameras before you leave, especially if there’s a hint of frost. Bridge decks on I-235 (like the one over 7th Ave) freeze way before the actual road does.
- Adjust your "buffer time" to 15 minutes for any cross-metro trip involving the I-80/35 west-side corridor until the University ramp opens this spring.
- Follow the Broadway Avenue detour maps if you're a regular north-side commuter; the local access routes are changing as they move into Stage 3 of the project this year.
