The Arizona Department of Transportation will be doing construction on Loop 303 from the US 60 to I-17 in Phoenix, Peoria and Surprise. The work consists of installing closed circuit television cameras, dynamic message signs, mainline and ramp detection system, thermal cameras, fiber optic network infrastructure, power services and related components. This project is primarily for wrong-way driver detection.
Motorists who use the Loop 303 (Bob Stump Memorial Parkway) in the Northwest Valley should plan for closures and restrictions over the next several months – as the Arizona Department of Transportation begins a technology-improvement project. ADOT advises drivers to allow extra travel time while the closures are in place.
Crews began installing in-pavement traffic-flow sensors – also referred to as loop detectors – which provide a continuous stream of traffic data that’s used to monitor travel conditions, and help plan for future infrastructure improvements. Over the next several months, the project also will include installation of closed-circuit traffic cameras, thermal-detection cameras and electronic message signs.
The project encompasses nearly 10 miles of the Loop 303 (Bob Stump Memorial Parkway) in the city of Surprise. The $4.6 million project is occurring primarily between the US 60 (Grand Avenue) and the Northern Parkway, but other sections of the Loop 303 could be affected.
The purpose of the project is to improve traffic flow and safety on the Loop 303. Major project elements include:
• Installation of thermal detection cameras at Peoria Avenue and Cactus, Waddell, Greenway and Bell roads.
• Installation of 10 closed-circuit television cameras which enable ADOT to monitor travel conditions.
• Installation of five overhead signs which allow ADOT to provide drivers with information such as travel times; crashes along the route; upcoming construction work; and safety messages.
What to Expect
• Loop 303 and several on- and off-ramps will be restricted or closed while work is underway.
• Restrictions and closures are scheduled to occur within the project boundaries and in areas north and south of the project area.
• Plan for delays and detours; plan to use alternate routes at times.
• Work that will impact travelers will be scheduled during overnight hours and on weekends. Unless otherwise indicated, work that requires closures will not be scheduled on weekdays during daytime hours.
• Alternate freeways to consider for north-south travel include the Loop 101 (Agua Fria Freeway) and Interstate 17 (Black Canyon Highway).
The project is scheduled to be completed in summer of 2020. For more information, call the project hotline at 602-712-8530 or visit: https://azdot.gov/projects/central-district-projects/loop-303-technology-improvement-project-us-60-grand-avenue.
