The Arizona Department of Transportation will begin an improvement project on Monday, May 11 to reconstruct nine miles of State Route 264 between Ganado and Window Rock (mileposts 450-459).

The $12.3 million project, which is scheduled for completion this fall, will include the following:

• Overlaying the existing pavement with new asphalt
• Widening existing shoulders and installing new guardrail
• Installing new cattle guards and barbed wire fencing
• Extending existing drainage pipes for the widened roadway
• Construction of a new Fish Wash Bridge to replace the existing one

Work days will be Monday through Friday sunrise to sunset. Flaggers and pilot cars will be used to guide vehicles through the work zone in alternating directions and drivers should anticipate delays of up to 30 minutes.

A traffic signal may be used to regulate traffic across Fish Wash Bridge in alternating directions. If the signal is used, motorists will experience short delays as the signal transitions through its cycle. There will be narrow traffic lanes, wide load restrictions and a reduced speed limit through the work zone.

ADOT advises drivers to proceed through the work zone with caution, slow down, and be alert for construction equipment and personnel.
