US 93 Kingman AZ - I-10

ADOT has dedicated nearly half a billion dollars to widening and improving US 93 from Wickenburg to Hoover Dam over the last several years. ADOT's long-term vision is to transform this highly traveled route into a four-lane divided highway through the entire 200-mile stretch. The US 93 series of projects is a priority for ADOT and has significantly improved our state highway system to move people, goods and services more efficiently.

I have not driven it "recently" but it was fine 7-8 yrs ago. The above info is from the AZ DOT. It looks like the next phase around mile 116-119 will not begin until 2016.
