Map - US 160 Chinle Wash Bridge
Project Location:

US 160 on the Navajo Nation 

Type of Work:

Bridge replacement project


The Arizona Department of Transportation is initiating a bridge-replacement project on US 160 near milepost 429, west of Mexican Water on the Navajo Nation in the far northeastern part of Arizona.  Crews will remove the existing bridge and replace it with a new, precast concrete bridge. In addition, the $6 million project consists of realigning the roadway, installing new pavement markings and other related work. The new three-span bridge will be 280 feet long and nearly nine feet wider than the existing bridge. 

Girder bridges are one of the most commonly built and utilized bridges in the world.

Traffic Impacts:
  • Motor-vehicle traffic on the bridge is scheduled to be reduced to one lane only from May through November. 
  • A temporary traffic signal will be in place during this time to allow for alternating travel in both directions through the construction zone. Motorists should plan for extra travel time as delays up to 20 minutes are expected during the bridge-replacement project.

Demolition work on the Chinle Wash Bridge in far northeastern Arizona. Located on the US 160 in the Navajo Nation,
the structure will be replaced with a new $6 million three-span bridge by year’s end.
