US 160

PHOENIX – The Arizona Department of Transportation is busy installing new street lights along US 160 just east of Tuba City improving the safety of the road by increasing visibility at night.

The $700,000 project is adding 43 light poles extending the existing roadway lighting nearly 2 miles.

Street lighting improves visibility and safety while driving at night. According to a 2014 case study by the Federal Highway Administration, street lighting at rural intersections can reduce overall nighttime crashes by up to 40% and nighttime injury crashes by up to 25%.

There are many highways in Arizona named in honor of veterans, but portions of three in the northeast part of the state seek to honor Native Americans who have served in the military.

PHOENIX – A partnership with the U.S. Geological Survey’s Arizona Water Science Center is helping Arizona Department of Transportation engineers anticipate the effects of extreme weather on bridges and highways and design ways to handle it.

Since its start in 2014, this collaboration has evolved to improve ADOT's use data involving flooding, natural hazards and weather-related risks through the agency's Resilience Program.
