Why it matters
Work zones and flying stones
A cracked windshield often starts as a single stone strike. Freeway construction raises the odds for a simple reason: the road surface is torn up, shoulders are gravel instead of pavement, and trucks carrying dirt and aggregate share narrowed lanes with everyone else.
In 2026 the Phoenix area has more of that than usual. Maricopa County voters approved Proposition 479 in 2024, and the first projects it pays for began this year, on top of work already under way from the earlier regional freeway plan. The table below lists the ones a Phoenix driver is most likely to pass through.
The list
ADOT projects under way or starting
Timing is as ADOT gave it to reporters. Projects slip, closures change week to week, and ADOT posts current closures on its own site.
| Project | What is being built | Timing | Cost |
|---|---|---|---|
| Loop 303 at I-17, north Phoenix | Direct freeway-to-freeway ramps at the interchange, and Loop 303 widened west to 51st Avenue. The first Prop 479 project | Started late January 2026, finishing by 2028 | 129 million dollars |
| Loop 303, 51st Avenue to Lake Pleasant Parkway | Three lanes in each direction | Starting fall 2026 | Not published |
| Loop 101, I-17 to 75th Avenue | Two new lanes in each direction over 6.5 miles of the Agua Fria Freeway | Began September 2024, due spring 2027 | 140 million dollars |
| I-10 and Loop 101 interchange, West Valley | An elevated HOV bridge between the two freeways, wider lanes on both, and a new ramp from the southbound 202 to 91st Avenue | About three years from spring 2026 | Not published |
| Loop 202 Santan Freeway, Loop 101 to Val Vista Drive | Two lanes each way to Gilbert Road, one each way to Val Vista, and wider bridges | Began August 2024, due spring 2027 | 200 million dollars |
| Loop 303 extension, Van Buren Street to SR 85, Goodyear | About four miles of new freeway with 10 overpass bridges | Clearing began June 2026, due about 2030 | 613 million dollars |
| State Route 30, south of I-10 | A new West Valley freeway corridor | Construction scheduled 2027 to 2046 | Not published |
The Loop 101 widening between Shea Boulevard and Princess Drive in Scottsdale (108 million dollars) was due to finish in early 2026 and is left off the list.
Where it bites
Which drives carry the most risk
North Phoenix has the most overlap. Anyone commuting on I-17 past Happy Valley Road now drives through the Loop 303 interchange work, and the Loop 101 widening runs west from the same freeway toward Glendale. A driver going from Deer Valley to the West Valley can pass through both on one trip.
The West Valley is next. The I-10 and Loop 101 interchange sits where traffic near 83rd and 99th Avenues is already heavy, and the Loop 303 extension in Goodyear adds earthmoving and haul trucks a few miles further west.
The East Valley's main zone is the Santan Freeway between the 101 and Val Vista Drive, due to wrap up in spring 2027. Central Phoenix and Ahwatukee are lighter this year, though every freeway sheds the odd stone.
Driving through
Fewer chips in a work zone
- Leave more room behind any truck carrying dirt, gravel or rock. The stone that hits you usually comes from close in front.
- Stay out of the lane next to a gravel shoulder when you have a choice.
- Keep your wipers off a dusty windshield until you have washer fluid on it. Dry wiping drags grit across the glass.
- If a stone hits, keep driving and check the glass once you are parked somewhere safe.
After a strike
What to note when a stone hits
Write down the freeway, the nearest exit, the direction and the time, and take a dated photo of the damage. If the stone came off a truck, note the company name and the truck number. Arizona's load law, A.R.S. § 28-1098, requires loads to be secured so nothing drops or escapes, but getting a trucking company to pay is a separate matter from replacing your glass.
We replace windshields; we do not repair chips. If the damage is in your line of sight or the crack is spreading, send us the photo and the VIN and we quote the exact glass for your car. Our longer post on bangautoglass.com covers the steps after a hit in more detail.
