I would say it's unlikely. There is no reason I can think of to bother going that way if one is going from Littleton to Westminster. My two cents. =)
I almost always go to Boulder that way, and I live quite near to ACC. Traffic through the middle of town has been bad, with the whole construction bit around Santa Fe and I-25. (ACC is located on Santa Fe, so that's the way you'd go.) I also love the scenery that direction (those wide open spaces), and some of prefer to be driving rather to be sitting in crappy gridlock on the interstate in the midde of a city. It isn't the most direct way to Westminster, no, but it is an option.
