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

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

Contents

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, which began in late spring 2022 and is scheduled to end 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).
