Actually there are, at least, 100 different routes you could follow, but if you are interested in the fastest route I-70 would be the one. I-70 does have mountains (the Colorado Rockies) and I-15 crosses three passes between Los Angeles and Las Vegas but it is the straight shot. Interstate highways are easy to travel and the mountains shouldn't be thought as that much a challenge to travel.Originally Posted by sd1023x
There are about six major routing programs, Mapquest is just one of them -- the thing you have to keep in mind is that no matter what Mapquest or MSN, etc suggest as the time of travel -- when one factors in fuel stops, rest stops, construction, urban congestion, and eating, the best average speed you will ever be able to do on a 8-hour basis is 53 mph (to average 65 mph over 8-10 hours you would need to be going close to triple digits when on the road). A reasonable time period for this drive would be five days.Is mapquest the fastest route? It seems to have many exits and many many different freeways in which I can possibly make a wrong turn.
There are hundreds of route suggestions on this forum and elsewhere in the site for such a cross country adventure. Remember to have some fun!
