If you’re currently sitting in gridlock on the I-10 or staring at a sea of brake lights on the Santan, you probably want to scream. Phoenix traffic has a way of turning a quick Saturday errand into a soul-crushing saga. Honestly, it feels like the Valley just never stops growing, but today? Today is particularly rough.
Why is there so much traffic in phoenix today? It isn’t just your imagination or a case of "Saturday drivers." It's a perfect storm of massive infrastructure projects kicking off for 2026, a specific holiday weekend travel surge, and some pretty major local events that have basically turned the Southeast and Northwest Valleys into parking lots.
The Weekend Squeeze: ADOT’s 2026 Project Kickoff
We’re officially in the era of Proposition 479. If you aren't familiar, that's the half-cent sales tax extension voters passed in late 2024. While it's great for the future of our roads, it means 2026 is the year of the orange cone.
Right now, the Loop 202 Santan Freeway is the biggest headache. ADOT has closed the eastbound Loop 202 in the Southeast Valley for widening work. This isn't just a minor lane shift. We’re talking about full on-ramp closures at Gilbert Road, Lindsay Road, and Val Vista Drive. If you usually take the 202 to get to the SanTan Village or into Gilbert, you’ve likely been funneled onto Williams Field or Germann roads, which are now absolutely choked with detour traffic.
Then you have the Loop 101 Agua Fria in the Northwest Valley. Between 19th and 31st Avenues, the lanes have been squeezed down to just two in both directions. It’s part of the ongoing widening project that’s supposed to wrap up later this year, but for today, it means a massive bottleneck for anyone trying to get toward the Arrowhead area or over to I-17.

Why Saturday is worse than Friday
Typically, we expect the worst traffic on Friday afternoons. But because this is the Martin Luther King Jr. Day weekend, the travel patterns are flipped. You’ve got people heading out of town toward Sedona or the White Mountains, mixed with thousands of locals trying to hit the various festivals happening around the Valley.
Hot Air Balloons and Westgate Crowds
If you’re wondering why the I-10 near Wild Horse Pass looks like a disaster zone, look up. The Arizona Balloon Classic is happening right now at the Wild Horse Pass Festival Grounds. It runs from January 16 through the 18th.
Events like this are notorious for "rubbernecking" delays. Even if the traffic is moving, people slow down to look at the dozens of colorful balloons in the sky. When you combine that with the second phase of the I-10 Wild Horse Pass Corridor widening project—which is literally happening right in that same stretch—you get a recipe for a three-mile backup.
Over in Glendale, the Westgate Entertainment District is also seeing a massive surge. Between the outdoor ice skating at Skate Westgate and the usual Saturday night crowds for the bars and restaurants, the 101 and the surface streets around 91st Avenue are slammed.

The "Invisible" Delays: Recent Crashes and Utilities
Sometimes the traffic isn't caused by a planned closure, but by the leftovers of a bad night. Late last night, there was a major crash on the westbound I-10 near Dysart Road. While the lanes are technically open now, the "hangover effect" of major accidents often lingers. Emergency repairs to barriers or lingering debris can keep speeds down long after the tow trucks leave.
Inside the city limits, Phoenix’s Street Transportation Department has dozens of active utility projects.
- 107th Avenue and Indian School Rd: Partial closures for utility work.
- 12th Street near Van Buren: Various street improvements that are restricting lane flow.
- Buckeye Road: Ongoing reconfiguration for the Sky Harbor Taxiway project.
If you’re trying to get to the airport today, basically add 20 minutes to your GPS estimate. The construction around Sky Harbor is currently impacting the West End, and with the holiday weekend travel volume, the terminal drop-off zones are hectic.
How to actually get around the mess
Look, Google Maps is usually your best friend, but even it struggles when three different detours merge into one lane.

- Use the "Secret" East-West Routes: If the 202 is dead, don't just follow the crowd to Germann. Try going further south to Queen Creek Road or even Hunt Highway if you're traveling between Chandler and San Tan Valley.
- The 511 is your bible: The Arizona 511 system (provided by ADOT) is significantly more accurate for construction-specific lane closures than some commercial apps. Check their live cameras before you leave the house.
- Avoid the 101/I-17 Interchange: If you're in North Phoenix, that widening project between 75th Ave and I-17 is a constant trap. Use Union Hills Drive or Beardsley Road (the frontage road) to bypass the heaviest freeway segments.
What’s coming next?
The reason why is there so much traffic in phoenix today is largely due to the sheer volume of work being done to keep up with the population. We're currently seeing the start of the SR 347 improvements toward Maricopa and the continued expansion of the Loop 303 in the West Valley.
Basically, the "Orange Cone State" isn't going away anytime soon. With the Broadway Curve project finally being "done" (mostly), ADOT has shifted all those resources to the 101, the 202, and the North I-17.
Actionable Advice for Valley Drivers
If you have to be on the road today, do yourself a favor: check the ADOT Weekend Freeway Travel Advisory before you put the car in reverse. If your route involves the eastbound Loop 202 or the northern Loop 101, find an alternative or leave at least 30 minutes earlier than you think you need to. Most of today's heavy restrictions are scheduled to lift by Sunday or Monday morning, but for right now, patience is the only real tool you’ve got.
Stay off your phone, watch for the workers in the "Work Zones," and maybe find a good podcast. It’s going to be a long afternoon on the asphalt.
Current Major Detours to Note:
- Eastbound Loop 202 (Santan): Exit early at Arizona Ave or McQueen and use Williams Field Rd.
- Northbound Loop 101 (Agua Fria): Bypass the 19th/31st Ave bottleneck by using 7th Ave to Happy Valley Rd.
- I-10 Southbound: Expect heavy gawker slow-downs near Wild Horse Pass due to the Balloon Classic through Sunday evening.
