Stuck in traffic on Phoenix’s Mini-Stack? ADOT wants your input on fixes

If you think Phoenix’s rush-hour traffic is bad now, just wait.

Rush-hour delays around the Mini-Stack could grow by up to 60% by 2050 if nothing changes, according to ADOT. The agency is asking the public for ideas to fix the interchange where Interstate 10, State Route 51 and Loop 202 meet.

The state is has an ongoing study that covers I-10 from the Deck Park Tunnel to the I-10/I-17 “Split” interchange near Phoenix Sky Harbor International Airport. It also includes SR 51 south of Thomas Road and Loop 202 west of 24th Street.

“Anybody that’s driven through there, many times of the day, not just at rush hour, will attest to the fact that there are some challenges there,” ADOT spokesman Doug Nick told KTAR News 92.3 FM’s The Mike Broomhead Show on Wednesday.

The corridor averaged more than five crashes a day from 2016 through 2021, warns ADOT.

Possible solutions include “collector-distributor roads” like those on the Broadway Curve, more lanes and new or relocated ramps. ADOT is also considering leaving the freeway as is.

“It is conceivable that we would do nothing. That is always an option,” Nick said. “But I would be very reluctant to say that that’s a likely outcome.”

How to weigh in on Phoenix Mini-Stack plans

ADOT will hold an in-person meeting from 5:30-7 p.m. Nov. 5 at Garfield Elementary School with a formal presentation at 6 p.m. A virtual meeting is scheduled on Nov. 9. You can register and by clicking here.

A public hearing on the draft environmental assessment is expected in late 2027 or early 2028. Construction would follow and take several years.

“It’s not going to be overnight, obviously,” Nick said.
