I-10 in Phoenix, segment by segment, breakdown by breakdown.

Why we built a corridor page

The I-10 is the spine of the Phoenix metro. It runs from the California border near Quartzsite, through Tonopah, into Buckeye, through Goodyear, into the downtown stack at I-17, out east through the airport into Tempe, then south through Chandler and out toward Tucson. That's 90 miles of freeway inside Maricopa County. The breakdowns we get on I-10 segment vary by location: summer overheating dominates the western stretch, accident calls dominate the downtown stack, commute fender-benders dominate the eastern stretch.

We get more I-10 calls than any other freeway. This page is the operational playbook our dispatchers use, written down so you can use it too.

Segment 1: Tonopah to Loop 303 (the west desert stretch)

Mile markers 92 to 124. ~32 miles. This is the most heat-exposed stretch in our service area. There is no shade, no continuous shoulder pull-off, and limited cell coverage in pockets. The summer pavement temperature regularly exceeds 165°F, and tire blowouts are the most common failure mode. Overheating runs second.

Safe pull-off spots: the rest area at MP 109, the Verrado Way exit (gas, food), Wintersburg Road exit (gas), and 411th Avenue exit (gas, food). Avoid pulling onto the inside shoulder anywhere on this stretch, the median is narrow and the pull-off geometry is bad.

Average dispatch time from our central yard: 35-50 minutes depending on segment. We'll quote the long-haul rate honestly on the call.

Segment 2: Loop 303 to Estrella Parkway (Goodyear gateway)

Mile markers 124 to 132. ~8 miles. This stretch transitions from desert to suburb. Loop 303 connects to north Glendale and Surprise. The shoulders widen at the Loop 303 interchange, and there are gas stations and food at every exit from here east. Average ETA from our yard: 28-38 minutes. Most common failure: overheating in summer, dead batteries year-round.

Segment 3: Estrella Parkway to 91st Avenue (Goodyear, Avondale)

Mile markers 132 to 138. ~6 miles. Suburban commercial. The Goodyear and Avondale exits provide easy off-ramp shelter. Average ETA from our yard: 24-32 minutes. The 99th Avenue exit (Cardinals stadium routing) and the 91st Avenue exit are the two most common pickup spots on this segment.

Segment 4: 91st Avenue to 35th Avenue (Maryvale to the stack approach)

Mile markers 138 to 144. ~6 miles. This is where the I-10 starts to feel urban. Heavy industrial along 67th and 51st Avenues. The shoulders narrow as the freeway approaches the stack. Average ETA from our yard: 18-25 minutes. Most common calls: tire blowouts (heavy truck debris on the road surface), commute fender-benders.

Segment 5: 35th Avenue to SR-202L split (the stack, downtown Phoenix)

Mile markers 144 to 152. ~8 miles. The most accident-prone stretch in central Arizona. The interchange where I-10, I-17, and SR-202L all converge produces a steady stream of fender-benders and more serious collisions. The lane geometry is complex with multi-level flyovers, and the merge points produce a high accident rate.

Average ETA from our yard: 10-18 minutes. The most common collision spots are the I-10 eastbound merge at I-17 northbound, the I-10 westbound exit to 7th Avenue, and the SR-202L eastbound transition to I-10 eastbound. Tell the dispatcher one of those and we know exactly where to route.

Pull-off advice: avoid the inside shoulder anywhere on the stack, the median is narrow and dangerous. The right-side shoulder is wider but still requires a rolling block from Arizona DPS for any serious recovery work.

Segment 6: SR-202L split to Loop 101 (airport, Tempe approach)

Mile markers 152 to 156. ~4 miles. The eastern edge of downtown. Sky Harbor airport access here. The Buckeye Road exit serves the airport long-term lots. Average ETA from our yard: 12-18 minutes. Most common calls: airport-area lockouts (drivers who realized they left keys at home after starting a trip), commute fender-benders.

Segment 7: Loop 101 to SR-202 (Santan) (Tempe and Chandler approach)

Mile markers 156 to 162. ~6 miles. Suburban commute zone. Heavy morning and evening rush hour from Chandler tech- corridor commuters. Average ETA from our yard: 18-25 minutes. Most common calls: rush-hour fender-benders at the Baseline Road and Ray Road interchanges.

Past the SR-202 (Santan) split, the I-10 continues south toward Tucson with limited services. We do tow that stretch but it's long-haul pricing.

Construction zones, what to expect right now

Arizona DOT runs continuous reconstruction on I-10. The Broadway Curve project has reshaped the I-10 between Loop 202 and US-60 with widened lanes and modified ramps. Lane shifts during construction add accident risk. If you're in a construction zone and the vehicle is still drivable, the safest option is to continue to the next exit and pull off in the parking lot of a gas station rather than stop on the construction-narrow shoulder.
