The good news is that NDOT has a plan in the works to build a six-lane freeway through the Carson Valley, with overpasses, real interchanges, and frontage roads running along either side. The bad news is that it isn’t going to be built until the year 2030. So just stick around another 23 years, and all your traffic problems will be over.
Of course the problem with this is that every second that ticks by, the costs of building such a freeway go up. So if you think it would be expensive to build now, just wait 23 years and see what the price tag looks like. So this is probably going to turn into another Carson City freeway fiasco, where it takes 50 years to get built and costs hundreds of times what it would if they had just stopped dithering and built the thing.
But at least we’re getting our cable barrier, so that will stopgap everything for the next 23-50 years.
