Went from Teslin to Tok today, 506 miles in 10 hours engine time. Almost all frost heaves have been repaired, and the red cones or flags left in place. After Donjeck River (about 125 miles from Beaver Creek) there is gravel, and the first mile was washboard, so be aware. There is around 25 miles of gravel in various stretches, most of it has a lot of fines so the surface is well packed and hard, and the water truck has kept much of it moist.
This is the absolute best I have seen the road in the last 10 years, the trip today was 2 hours shorter than last year, and 3 hours shorter than in previous years. Bear in mind that we did it on Sunday, your results may vary during the work week.
Best wishes to all for a great trip.
