PHOENIX – Work is underway on a freeway widening project designed to address rising traffic demands near the TSMC Arizona campus in north Phoenix.
The project will add one general-use lane in each direction of Loop 303 between Interstate 17 in north Phoenix and Lake Pleasant Parkway in Peoria over the next three years. The 7-mile stretch, part of which runs just south of the 1,100-acre TSMC Arizona semiconductor manufacturing site, currently has two lanes each way.
As part of the project, a new direct connection from I-17 to Loop 303 will be built.
How long will Loop 303 freeway widening project take?
The Loop 303 project is scheduled to be completed in mid-2028, according to the Arizona Department of Transportation.
The construction schedule is broken down into three phases, the first of which started over the weekend and is expected to take four months.
The initial phase is focused on improving the northbound Interstate 17 ramp to Sonoran Desert Drive. Crews will add a second lane, create a storm drain, install new overhead signs and restripe I-17 to accommodate the updates.
Motorists should anticipate lane restrictions in the area – but no I-17 closures — during the first phase, which should wrap up in January.
What’s next for freeway widening project?
Phase two will start afterward and last until the end of the project in mid-2028. It entails the construction of new Loop 303/I-17 interchange ramps as well as the freeway widening work between I-17 and 51st Avenue.
Phase three, which is scheduled to run from spring 2026 to late 2027, involves widening Loop 303 between 51st Avenue and Lake Pleasant Parkway. Additionally, crews will build bridges to accommodate a future exit at 67th Avenue.
ADOT is overseeing the freeway widening project in partnership with the Maricopa Association of Governments and the cities of Phoenix and Peoria.

Stop adding more lanes. Expand your bus routes or have the company pick up the employees with their own bus. Why?
Most people hate their cars. They all look alike, for one thing. They may be named after predators, or primitive emotions, or astronomical objects, but in essence they are a big shiny sink down which the money swirls—in insurance, car payments, tags, tolls, tires, repairs. They give you a chance to sit in helpless rage, beating on the steering wheel in a blare of horns while, a mile away, your flight leaves the airport. They give you a good chance of dying quick, and a better chance of months of agony of torn flesh, smashed guts and splintered bones. Take it to your kindly dealer, and the service people look right through you until you grab one by the arm, and then he says: Come back a week from Tuesday. Make an appointment. Their billions of tons of excreted pollutants wither the leaves on the trees and sicken the livestock. We hate our cars. Those of us who can possibly get along without them do so very happily. For those who can’t, if there were an alternate choice, they’d grab it in a minute. We buy them reluctantly and try to make them last, and they are not friendly machines anymore. They are expensive, murderous junk, and they manage to look glassily contemptuous of the people who own them.
