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.
