Hi, my first post here. I am planning a trip from Winnipeg in Canada to LA in August. Im going to be driving through Denver and then hoping to take some detours through Utah and see some national parks along the way, also saving some time. So my question is if I take the 191 and then the 160 will this save me time? rather than going the freeway? Also, are these roads sealed the whole way? I read somewhere that some of these roads are not. Thanks.
