I-17 Southbound: Coconino County Line - McConnell Bridge Pavement Rehabilitation

This project has been paused due to winter weather conditions and
will resume in spring 2023.

Project Overview

Project Cost: $34,954,000


The Arizona Department of Transportation is initiating a pavement and bridge rehabilitation project on southbound Interstate 17 between the McConnell Drive Bridge in Flagstaff and the Coconino County line (mileposts 311-340).

The primary purpose of the project, scheduled to begin in late spring 2022 and ends in fall 2024, is to perform much-needed repairs and upgrades to the road surface on this heavily traveled stretch of southbound I-17.

In addition to the travel lanes and shoulders, several on- and off-ramps and nine bridges within the project area will be repaved. Similar work already was performed on the northbound side of the roadway.

Additional pavement improvements will occur on State Route 89A near milepost 402 and on northbound I-17 near Munds Park (milepost 323).

Project Fact Sheet


Restrictions and Closures

Drivers should expect southbound I-17 to be restricted to one lane around-the-clock at various locations. Lane restrictions are currently in place from mileposts 330-328, from 323-320 and from 313-311. Drivers should be prepared to slow down and proceed through the work zones with caution.

For information about project-related restrictions and closures please visit az511.gov or call 511, except while driving.

Other nearby 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 SR 89A Oak Creek Improvements project currently underway. As a result, drivers may experience additional delays on SR 89A, if they should choose to use the roadway as an alternate route.
