The Arizona Department of Transportation advises Flagstaff drivers who use McConnell Drive to plan for a full overnight road closure while crews continue work to replace the McConnell Bridge on Interstate 17 and State Route 89A approaching Flagstaff.

McConnell Drive under I-17 will be closed in both directions from 8 p.m. Sunday, October 20, to 6 a.m. Monday, October 21.

Motorists should follow signed detour routes and plan for travel delays.

The project involves a full bridge deck replacement, bridge widening and sidewalk construction on the north side of McConnell Drive. Work is scheduled in three phases over two years with completion scheduled for fall 2020.
