Interstate Highway Analysis
I-235 (The Des Moines Crosstown)
- Length: 13.7 miles through central Des Moines
- Daily Vehicles: 100,000-120,000 (between 42nd St and Downtown)
- Critical Chokepoints:
- 42nd Street entrance (AM eastbound backup begins here)
- Keo Way interchange (Downtown access point)
- 63rd Street area (westbound evening bottleneck)
- Best Alternative: University Avenue parallels entire corridor with 8-12 minute longer travel time but more consistent speed
I-35 Through Des Moines
- Segment Analysis:
- North of I-80: Moderate congestion, primarily near Ankeny exits
- Between I-80 and I-235 (Mixmaster): Most complex interchange in Iowa, frequent slowdowns
- South of Downtown: Generally lighter except near Army Post Road interchange
- Mixmaster Strategy: When approaching from north or south, consider exiting at 2nd Avenue or East 14th Street to bypass the interchange during peak hours
I-80 East-West Corridor
- Western Suburbs (Waukee/West Des Moines): Morning eastbound delays begin at 7:15 AM near Grand Prairie Parkway
- Eastern Suburbs (Altoona): Evening westbound congestion near Adventureland Drive (4:30-5:45 PM)
- Through Traffic Tip: Consider IA-5/US-65 as bypass for north-south traffic avoiding Des Moines entirely
Best Alternative Routes by Corridor
East-West Alternatives to I-235
| Route | Best For | Distance | Time vs I-235 | Traffic Lights |
|---|---|---|---|---|
| Grand Avenue | Downtown to Western Suburbs | 7.2 miles | +8-12 minutes | 22 |
| University Avenue | Full east-west bypass | 11.5 miles | +10-15 minutes | 28 |
| Hickman Road (US-6) | Northwest bypass | 9.8 miles | +6-10 minutes | 18 |
| Douglas Avenue | Urbandale to Downtown | 5.5 miles | +5-8 minutes | 16 |
North-South Alternatives to I-35
| Route | Best For | Key Advantage | Peak Hour Speed |
|---|---|---|---|
| Merle Hay Road | North suburbs to Downtown | Bypasses Mixmaster entirely | 35-45 mph |
| SE 14th Street | Southside to Downtown | Avoids I-35 army post congestion | 30-40 mph |
| Fleur Drive | Airport & Southside access | Scenic route, consistent flow | 40-50 mph |
| 2nd Avenue | Downtown north access | Direct, fewer trucks | 25-35 mph |
Route-Specific Strategies
Downtown to Airport During Rush Hour: Despite being 0.6 miles longer, Fleur Drive saves 12-18 minutes versus I-235 during 4:30-5:45 PM period. The consistent 40 mph flow with only 7 traffic lights proves more reliable than the stop-and-go interstate.
West Des Moines to Ankeny: During 4:00-6:00 PM, take Hickman Road (US-6) east to NW 66th Avenue north, then connect to NE 46th Street into Ankeny. This 22-minute route often beats the 35+ minute I-35/I-80 combination.

- Broadway Viaduct (connecting Downtown to Southside): Icy conditions frequently require salt trucks
- I-35 bridges over the Raccoon River: Freeze before other road surfaces

Local Driver Insights & Unwritten Rules
Des Moines-Specific Driving Behaviors
- "Iowa Nice" Merging: Drivers generally allow zipper merges at construction zones - use this to your advantage
- Winter Driving: Snow routes are strictly enforced - parked cars will be towed during snow emergencies
- Farm Equipment: Occasional slow-moving farm vehicles on outskirts - especially during planting/harvest seasons
- Event Parking: Downtown events often have $5-10 lots just outside the core that require 5-10 minute walk but save 20+ minutes exiting
Pro Tips from Longtime Commuters
- Westbound I-235 Escape: If trapped in standstill traffic west of Downtown, exit at 6th Avenue and take Center Street to 63rd Street to re-enter
- Airport Shortcut: When approaching from east, use Army Post Road to Hartz Drive to avoid the congested Fleur/Airport Road intersection
- Friday Afternoon Hack: Leave before 3:00 PM or after 6:30 PM - the 3:30-6:00 period is the week's worst
- Rainy Day Strategy: Add 50% to normal commute time and avoid I-235 between 42nd and 63rd (becomes parking lot)
- Construction Season: Always check 511ia.org before weekend travel April-October
Neighborhood-Specific Advice
- Beaverdale: Hickman Road is fastest east-west, but Urbandale Avenue often smoother during peak
- Waterbury: Use 56th Street to bypass University Avenue congestion
- South of Grand: Grand Avenue has timed lights favoring eastbound AM, westbound PM
- East Village: E Locust Street is less congested than Grand Avenue for east-west movement
Real Case Study: A regular commuter from Ankeny to Downtown switched from I-35 to taking NE 46th Street to Merle Hay Road, then 2nd Avenue downtown. Despite being 1.4 miles longer, the consistent 35-45 mph speed saved 8-12 minutes daily during PM rush hour, totaling 40-60 minutes weekly savings.
Frequently Asked Questions
What are the worst traffic times in Des Moines?
A. Weekday mornings 7:00-9:00 AM and evenings 4:00-6:30 PM are peak congestion periods, particularly on I-235, I-35, and I-80 through the metro area. The absolute worst single hour is 5:00-6:00 PM on I-235 westbound between downtown and 63rd Street.
What's the best alternative to I-235 during rush hour?
A. Grand Avenue, University Avenue, and Hickman Road (US 6) serve as effective east-west alternatives to I-235 with less congestion during peak hours. For specific segments: Downtown to western suburbs use Grand Avenue; full east-west bypass use University Avenue; northwest movement use Hickman Road.
Where do most traffic accidents occur in Des Moines?
A. The I-235/I-35 interchange (Mixmaster), Merle Hay Road at I-80, and the East 14th Street corridor have the highest accident rates according to Iowa DOT data. In 2023, these three locations accounted for 32% of all reported accidents on controlled-access highways in Polk County.
Is there a time when Des Moines traffic is consistently light?
A. Yes, weekdays between 10:00 AM and 2:00 PM, weekends before 11:00 AM, and weekdays after 7:00 PM typically have minimal traffic congestion. Sunday mornings before noon are particularly light throughout the metro area.
What's the best route from downtown to the airport during rush hour?
A. Use Fleur Drive instead of I-235. Although slightly longer (5.8 miles vs 5.2), it saves an average of 12-18 minutes during peak congestion periods. The consistent 40 mph flow with only 7 traffic lights proves more reliable than the stop-and-go interstate which can drop to 10-15 mph.
How much longer does rush hour add to Des Moines commutes?
A. Peak hours add 25-40 minutes to typical cross-metro commutes, with I-235 westbound experiencing the greatest delays (up to 50% longer travel times). For example, a normal 15-minute I-35 commute from Ankeny to Downtown becomes 38 minutes during evening rush hour.
What are the main construction zones affecting Des Moines traffic currently?
A. Major ongoing projects include the I-35/I-80 West Mix improvements (through Oct 2024), University Avenue bridge repairs (through Aug 2024), and the SE 14th Street reconstruction (through Nov 2024), all adding significant delays of 10-25 minutes to affected routes.
Does Des Moines have HOV lanes or other traffic management systems?
A. No HOV lanes exist. Primary management includes 511ia.org real-time traffic updates, 80+ traffic cameras monitored by Iowa DOT, and variable message signs on major corridors. Des Moines also uses adaptive traffic signal timing on 11 major corridors that adjusts based on real-time traffic flow.
