During Phase 2, which began in July 2022, crews will focus on completing the construction of the new 48th Street and Broadway Road bridges over I-10; building collectordistributor roads; constructing the new bridges at the U.S. 60/I-10 interchange; relocating utilities; and building new barrier walls.
This project also includes widening the Guadalupe Road bridge over I-10 to improve the Sun Circle Trail, a 300-mi. loop trail used by pedestrians, cyclists and equestrians.
“This project is our largest urban freeway reconstruction project to date,” said Marcy McMacken, spokesperson of the Arizona Department of Transportation (ADOT).
This project also will prepare the region for future growth projections, which indicate a 25 percent increase in traffic through the Broadway Curve area by 2040. Currently, more than 300,000 vehicles pass through the Broadway Curve area on an average weekday.
This complicated undertaking will cost $776 million.
ADOT has broken the project into three segments: • West segment: East and westbound I-10 from 24th Street to the east of 40th street and will include the I-10 bridges over the Salt River; • Central segment: East and westbound I-10 east of 40th Street and Broadway; and 1 mi. of Route 143 in both directions between I-10 and the Salt River; • East segment: East and westbound I-10 between Broadway and Ray roads and including 1 mi. of U.S. 60 in both directions between I-10 and Hardy Drive.
Work will be happening on all segments simultaneously and will involve widening, paving, bridge construction and utility relocations. Phase one is finished with work under way on phase two. Green Construction
Planners and workers have given special emphasis to environmental responsibility. Recycling used construction materials has been made a priority.
Some 1.3 million sq. yds. of millings are being used as the base layer for temporary haul roads in the project area. Millings provide a strong base for trucks and equipment to drive on and they help reduce dust.
Throughout the project, walls and other concrete structures are being taken down and reduced to pieces no larger than 24 in. Once broken down to the appropriate size, the concrete is used as fill to build up approaches for new bridges, fill up holes or help support unstable materials throughout the project area. The contractor sends unused metal and steel to a recycling factory. Challenges
Like most multi-year construction projects, COVID has had an impact.
COVID was not the only disruption.
“In May, the team needed to close I-10 in both directions and detour motorists to westbound U.S. 60,” McMacken said. “However, a water main broke under U.S. 60, creating extensive flooding and damaging the U.S. 60 road surface. U.S. 60 was closed for repairs for several days. Without a viable detour available, crews again pivoted and rescheduled work, exhibiting the ability to modify their construction work plans.”
ADOT is using new outreach tools, in addition to the traditional methods, to create awareness about this massive project.
“We launched ADOT’s first project-specific, bilingual paid advertising campaign in the summer of 2021,” said McMacken. “The campaign includes billboards as well as TV, radio, online, social media and paid search. Also, visitors who pass through Phoenix Sky Harbor International Airport will see project-related ads, so they are aware of the project construction taking place around the airport - which is in the heart of the busiest section of the project.”
ADOT opted to utilize the public-private partnership (P3) statute to procure, design and build this project. A public-private partnership design-build makes it possible to deliver much needed transportation projects in a timely manner, often years before the projects could be delivered using traditional project-delivery methods.
“Opening the new eastbound travel lanes early in the life of this massive project provides tremendous value to thousands of motorists,” said ADOT Director John Halikowski. “We are delighted we could make it happen and improve the afternoon and evening commute home for so many of our customers in Guadalupe, Tempe, Chandler and other areas of the Southeast Valley. We know this project is influential in other areas of I-10, the U.S. 60 and State Route 143. Opening up new travel lanes is one way we’re striving to reduce the project’s impacts for at least some motorists in the project area.”
McMacken also sees a big impact to travelers in the Broadway Curve and throughout Phoenix.
“Once completed, motorists will notice reduced travel time during peak hours and improved access to and from Phoenix Sky Harbor International Airport,” McMacken said. “They also will have improved access to the over 4,600 businesses within the project area, improved safety by reducing lane changes and ‘weaving’ on Interstate 10 in the Broadway Curve area and on State Route 143 at University Drive.

At the beginning of this year Wirtgen celebrated the market launch of its completely redesigned generation of compact milling machines. Technologies from the F-series large milling machines have now been integrated in the W 100 Fi, W 120 Fi and W 130 Fi compact milling machines.
Wirtgen also will be showing another innovation at bauma 2022 — for the first time, compact class machines can be fitted with a comfort cabin. This not only increases the safety of machine operators, but also the comfort of their workplace, according to the manufacturer.
Cold Milling Machine With
Environmentally Friendly Engine Technology
The front loaders with working widths of 3.3, 3.9 and 4.2 ft. feature the latest and currently most environmentally friendly engine technology compliant with EU Stage 5 / U.S. Tier IV Final exhaust emission standards. The diesel engine delivers a rated output of 355 hp. (265 kW).
Wirtgen and John Deere have precisely tuned the torque characteristic of the engine to meet the specific needs of the cold milling process. The engine already delivers sufficient torque at engine speeds as low as 1,200 rpm, achieves maximum torque at 1,500 rpm and offers a very wide working speed range of 1,200 to 2,100 rpm. As a result, the machines use significantly less fuel, even when delivering the highest productivity and milling at the maximum depth of 13 in. Mill Assist, WPT
Also onboard are the digital assistance systems Mill Assist, Wirtgen Performance Tracker (WPT) and the Level Pro Active leveling system, which have already delivered customer benefit in the F-series large milling machines. Now, customers can look forward to the benefits of high milling performance, maximum efficiency and clear documentation in the compact milling machine class.
The W 100 Fi, W 120 Fi and W 130 Fi compact milling machines from Wirtgen perform in a wide range of different applications, for example, for milling off surface layers or when milling tie-ins during road rehabilitation projects.
operating strategy with the most favorable balance between milling performance and operating costs. This increases milling performance while simultaneously reducing not only diesel fuel, water and pick consumption, but also CO₂ emissions.
Mill Assist automatically controls the engine speed and simultaneously provides a wide range of usable milling drum speeds for an enormous spectrum of applications. The low-speed range enables significant reductions in fuel consumption and minimizes pick wear. The upper speed range enables the achievement of an optimal milling pattern, even in the case of higher area performance rates.
The operator can additionally select one of three operating strategies for each milling job: “ECO”, “performance-optimized” or “milling pattern quality”. This makes it possible, for example, to pre-define the required milling pattern quality incrementally from coarse to very fine at the press of a button.
Wide Range of Applications,
Maximum Flexibility
Compact dimensions and optimized machine weight for easy transportation predestine these machines for a multitude of different construction site scenarios. Whether on highways, main roads, parking lots or inner-city streets — these high-performance machines are ideal for a broad spectrum of applications.
Due to their outstanding productivity, they are ideal for surface layer rehabilitation and complete pavement removal on construction sites of all sizes. Due to the ability to quickly change the FCS milling drums with different pick spacings and working widths, the compact milling machines from Wirtgen also can be rapidly reconfigured on-site to adapt to changing applications. Precise Leveling
With LEVEL PRO ACTIVE
Already proven in the F-series large milling machines, the LEVEL PRO ACTIVE leveling system has now been made available for the compact class milling machines. Developed by Wirtgen especially for cold milling machines, the leveling system features informative operating panels and is intuitive and easy to use.
All connected sensors and measured values are clearly displayed on the operating panel to make the work processes as efficient as possible. The system is fully integrated in the control system of the cold milling machine and, as essential machine functions are directly interconnected, provides a high level of automation.
The system also offers many automatic and additional functions that make the operator’s job easier, for instance, automatic lifting for driving over manhole covers.
Cockpit Also Available
With Enclosed Cabin
The newly developed operator’s cabin is characterized by ergonomically designed control elements with high-quality haptics and maximum ease of operation. In addition to the slender wasp waist of the machine, up to five on-board cameras provide an ideal view of all important working areas.
The new 5-in. control screen in the multifunctional armrest displays all machine-relevant information. The access ladder to the cabin at the rear of the machine is fitted with an automatic height adjustment system. This assures that the machine operator can easily and safely access the platform in all working situations.
At bauma 2022, Wirtgen is showing another innovation in the compact milling machine class — a completely enclosed comfort cabin. It protects the operator against typical problems such as noise and dust on the construction site and provides ideal working conditions in all kinds of weather.
