Road Construction Ahead

250 miles from Flagstaff to Las Vegas.  For the first 145 of them we had NINE road construction projects consisting of: Warning of construction ahead, lower speed limit coming. Reduction of speed from 76 to 65 to 55 to 45. Left (or right) lane closed ahead. Move traffic to said lane.  All of this taking about two miles to accomplish, then we finally get to the construction zone which invariably consisted of two pickup trucks and three or four guys working --maybe a 50 foot stretch--and for this we got to drive single file at 45 miles per hour for two miles.  Nine times in 145 miles.  You do the math.
