It is paved from end to end. I remember there being a small rock wall on the low side that may stop a majority of vehicles from accessing unpaved ground.
I think you're referring to "Going to the Sun Highway" in Glacier Park Mt.
Top of the World Highway is from Dawson City Yukon to Chicken Alaska.
To answer the OP's question...at one time the road was sorta paved on the Yukon side but once you get into Alaska, the road is all gravel and no, there are not many (if any) barriers on the side to keep you from going over. When we went on this highway (?) in 08, the Canadian side had a LOT of gravel parts with some pavement under the gravel.....no pavement on the U.S. side at all.
The road is built up with gravel such that there basically (in many parts) no shoulder at all, in fact, the closer you get to the shoulder, the more unstable the gravel is...especially with a very heavy rig like a large DP.
In addition, the road is used by logging and other large trucks that typically travel down the middle of the road at a higher rate of speed than I felt was safe. When a truck approached us, I would get over as far as I dared (usually about three or four feet from the edge) and stop and let the truck go by. Sometimes there wasn't much distance between our mirrors and was surprised we made it to Chicken with the mirrors intact.
It's only about a 100 miles, but it will take about 6 hours to travel it, more if you like to pull out and sight see. We stayed overnight at Chicken (did a little panning and checking out the dredge) and then drove on to Tok the next day. The road from Chicken to Tok starts out gravel but within a few miles turns into pavement.
Once we got to Tok, our mh and toad was tan or a dirty brown color. Took two hours to wash all the mud and dirt off of them. Tok RV Park has a wash area for rv's.
My DW says she'll never go over that road again, but I felt it wasn't all that bad. Take it slow and easy and enjoy the sights.
