They are designing I-11 this way to make use of US 93, which is almost in freeway condition for much of its length. Upgrading US 93 into I-11 is cheaper than building new.
UH Huh! And I am an airline pilot.
OK. Then explain what course they intend on taking to connect 93 to I-40 at Kingman?
Instead of taking off at Golden Valley south/west around the Cerbats and connect west of town at the old route 66 interchange, they want to go over the Coyote Pass. That way, they would only have to build ONE overpass over 68. All the interchanges are in except for the overpass.
When they go over that pass on 93, they havent anyplace to go other than just south/west of all the truck stops and make a huge rock cut to connect. That is, unless they intend on demolishing all the truck stops at that interchange...which I wouldnt be against. If they try and go to the north/east of there, they run into a historical site, tons of houses, and the Cerbats on the side of town.
