After July 2010, portions of the Taylor Highway have been much improved since the major washouts happened in that timeframe along the most rugged stretch between mile 66 (Chicken) and mile 96 (Jack Wade Junction).
Starting in August 2014, the 13 mile route of Boundary Spur Road (Mile 96 Taylor Hwy. to the International Border) has been completely paved and is real nice and smooth !
Do take your time and drive with care thru the unpaved and rugged parts of the route and you will be fine - this is NOT a route to be driving fast or pushing it trying to make time on in a large or heavy haulin' vehicle as not only potentially dangering yourself but others as well, especially on rainy days where the road surface will be washboarded quick !
