Plan for southbound I-17 on-ramp closure at Munds Ranch Road south of Flagstaff through October

The Arizona Department of Transportation is advising motorists to plan for an on-ramp closure at Munds Ranch Road on southbound Interstate 17 south of Flagstaff in the community of Munds Park as work continues on an extensive pavement project.

Starting at 6 a.m. Tuesday, Aug. 30, and continuing through October, the following around-the-clock restriction will be in place seven days a week:

  • The southbound I-17 on-ramp at Munds Ranch Road (milepost 323) will be closed.
    • Detour: From Munds Ranch Road, drive northbound on I-17 to the Willard Springs Road Exit (milepost 326), cross over the interstate and re-enter the highway driving southbound on I-17.

The project, which is expected to be completed in fall 2024, is improving 29 miles of pavement on southbound I-17 from the McConnell Drive Bridge in Flagstaff to the Coconino County line.

The Arizona Department of Transportation is advising motorists to plan for a new set of lane restrictions on southbound Interstate 17 south of Flagstaff as work continues on an extensive pavement project.

Starting on Thursday, Aug. 25, and continuing through October, the following around-the-clock restrictions will be in place seven days a week:

  • Southbound I-17 will be reduced to one lane at three locations between Kelly Canyon Road and Stoneman Lake Road (mileposts 330 - 328, 323 - 320 and 313 - 311).
  • A vehicle width limit of 13 feet will be in place.
  • The speed limit will be reduced to 55 mph.
  • Drivers should be prepared to stop and proceed through the work zones with caution.
  • The southbound I-17 on- and off-ramps at Newman Park Road (milepost 328) will be closed.
    • On-ramp detour: Drive northbound on I-17 to the Kelly Canyon Road Exit (milepost 331), cross over the interstate and re-enter the highway driving southbound on I-17.
    • Off-ramp detour: Drive southbound on I-17 to the Willard Springs Road Exit (milepost 326), cross over the interstate and re-enter the highway driving northbound I-17 to Newman Park Road.
    • A vehicle width limit of 13 feet will be in place.

The project, which is expected to be completed in fall 2024, is improving 29 miles of pavement on southbound I-17 from the McConnell Drive Bridge in Flagstaff to the Coconino County line.

The primary purpose of the project is to perform much-needed repairs and upgrades to the road surface on this heavily traveled stretch of I-17. In addition to the travel lanes and shoulders, several ramps and nine bridges within the project area will be repaired and repaved. Similar work was already performed on the northbound side of the roadway.

Nearby travel restrictions: Portions of State Route 89A between Flagstaff and Sedona are reduced to one lane only of alternating north- and southbound travel due to the State Route 89A Oak Creek Improvements project currently underway. As a result, drivers may experience additional delays on SR 89A, if they should choose to use that roadway as an alternate route.

 

Plan for lane restrictions on southbound I-17 south of Flagstaff as major paving project begins June 14

The Arizona Department of Transportation is advising motorists to plan for lane restrictions on southbound Interstate 17 south of Flagstaff as an extensive pavement rehabilitation project begins.

Starting on Tuesday, June 14, and continuing through the end of July, the following around-the-clock restrictions will be in place seven days a week:

  • Southbound I-17 will be reduced to one lane at three locations between Kachina Boulevard and south of Munds Park (mileposts 321, 331 and 333).
  • A vehicle width limit of 16 feet will be in place.
  • The speed limit will be reduced to 55 mph.
  • Drivers should slow down, be prepared to stop and proceed through the work zones with caution.

The project, which is expected to be completed in summer 2024, will rehabilitate and repave 29 miles of southbound I-17 from the McConnell Drive Bridge in Flagstaff to the Coconino County line.

This project is now complete

Overview

The Arizona Department of Transportation made improvements to the cross street drainage system along the Interstate 17 frontage road between Greenway Road and Dunlap Avenue in Phoenix. The purpose of the project is to improve the drainage facilities that remove storm runoff from the Greenway, Thunderbird, Cactus, and Peoria cross streets, helping to reduce the potential for flooding at the Interstate 17 overpasses.

Project Details

Construction started in early 2020. The new drainage system has been completed and is operational. The work included:

  • Removing the existing pump stations at Peoria Avenue, and Cactus, Thunderbird and Greenway roads. These pump stations were some of the oldest in the metro Phoenix freeway system.
  • Trenching and laying nearly 24,000 linear feet or four miles of large diameter concrete pipe. The pipe installed ranges in size from 54” to 90” in diameter.
  • Excavating two retention basins at Thunderbird Road. The basins are designed to collect and regulate outflow from the Thunderbird (the south basin) and Greenway (the north basin) cross streets.
  • Tunneling of two 300’-long pipes nearly 30’ deep underneath I-17. This method of pipe installation allowed crews to work without the need to restrict or close mainline I-17.

Additional activities will continue for the next few months to complete minor work items, some of which may require lane restrictions.
