FLAGSTAFF – An Arizona Department of Transportation project underway at the Twin Arrows interchange along Interstate 40 just east of Flagstaff will improve access for drivers.

The $4.5 million project between mileposts 218 and 220 will create new eastbound off- and on-ramps, and improve the bridge structure with new girders, wider abutments, a widened and repaved deck, and new safety barriers.

I-40 drivers will encounter a lane restriction in both directions at the interchange as work continues. Access to Twin Arrows Road and I-40 will be maintained, though occasional detours can be expected. Work is expected to be complete by fall.
