Interstate 17/State Route 89A McConnell Bridge

The Arizona Department of Transportation and the Federal Highway Administration are replacing the McConnell Bridge, located on Interstate 17/State Route 89A approaching Flagstaff. Work is scheduled to begin in summer 2019.

The project involves a full bridge deck replacement, bridge widening and sidewalk construction on the north side of McConnell Drive.

The project is scheduled in three phases over two years with completion scheduled for fall 2020.
