11    HOUSEHOLDER PASS and BOULDER DAM AREA

            (on US 93 between Kingman, AZ and Boulder Dam)

            If you are traveling north on US 93 from Kingman to Boulder Dam, the last 16 miles before reaching the dam are a roller coaster ride.  There are uphill grades and downhill grades that range from 2% to 6%.  The last 6 miles, starting at milepost 6½ are mostly 5-6% descent.  The road becomes curvy and steep near the dam with 15 and 25 mph curves as you turn onto the dam.  Going from Boulder City, Nevada toward the dam there is a hill about 3 miles long at 4-5% and then the grade eases for about a mile before going to 5-6% the last 2 miles to the dam.  There are 15 mph curves near the bottom of the hill.
