Two highway construction projects will be affecting the northwest valley in 2024.
I-17 Happy Valley Road to SR 74 Pavement Project
The Arizona Department of Transportation is initiating a project to repair the pavement on Interstate 17 from Happy Valley Road to State Route 74. The purpose of the project is to extend the life of the pavement and to improve safety and the driving experience on the roadway.
Construction is scheduled to begin spring 2024 and take approximately seven months to complete. More information will be posted regarding the construction duration prior to the work starting.

Loop 101: 75th Avenue to I-17 Improvements
The Arizona Department of Transportation, in cooperation with the cities of Glendale, Phoenix and Peoria, the Federal Highway Administration and the Maricopa Association of Governments, has initiated a project to widen and make other improvements to the Loop 101 (Agua Fria Freeway) between 75th Avenue in Glendale and Interstate 17 in Phoenix. The project seeks to address growing traffic demands in the northwest Valley and relieve traffic congestion on the Loop 101 during the morning and evening peak travel periods. The project will connect with the Loop 101 Pima Freeway widening project east of I-17, completed in 2022.
Project Elements
- Widen Loop 101 by one general purpose lane in each direction to the outside within the existing freeway right of way
- Restripe the westbound Loop 101 ramp to northbound I-17 to add another lane
- Widen bridges at 51st, 35th and 31st avenues to accommodate new lanes on Loop 101
- Widen exit ramps to two lanes and reconstruct ramp connections to new freeway lanes in several locations
- Widen frontage roads to two lanes approaching exit ramps in several locations to improve traffic flow
- Modifying interchange ramps and retaining walls to accommodate the freeway widening
- Interchange and cross street improvements at 75th Avenue, to include:
- Add capacity and improves traffic flow for morning peak travel
- Add a third turn lane on southbound 75th Ave to enter eastbound Loop 101
- Lengthen southbound left turn bays to allow more vehicle storage (requires closing median opening)
- Add a lane on eastbound Loop 101 on-ramp
- Add a lane on eastbound Loop 101 between 75th and 67th Ave to provide more distance for vehicles entering or exiting the freeway
- Interchange design strongly preferred by community members versus other design alternatives based on a community survey
- Improve the 67th Avenue ramp
- Accommodate additional auxiliary lane from 75th to 67th Avenues with a two-lane exit ramp. Modify ramp and frontage road configurations in some locations, reconstruct ramp connections to new freeway lanes
- Add or modify noise walls in some locations based on noise analysis
- Resurface pavement on freeway with diamond grinding treatment
- New freeway striping and signage on freeway
- New ramp meters
- Freeway drainage improvements
- Convert existing freeway lighting to LED
- Replace impacted landscaping.
- New noise walls locations:
- 47th – 44th avenues (south side) to connect to existing wall between 51st and 47th avenues
- 36th – 34th avenues (south side) to extend sound barrier protection through the 35th Avenue bridge
- 35th – 31st avenues (north side)
- Existing noise wall modification locations:
- 51st – 47th avenues (south side)
- 43rd to 37th avenues (south side)
- New/modified walls to have same design aesthetics as current walls
Per current program funding, project construction is anticipated to begin in fall of 2024
