The new 8-inch-wide rumble starts a couple of miles north of Watertown, passes through the town, and ends at the Dekalb county line. At either end it joins with rumbling applied in the prior years. North of the town US70 is profusely signed (every quarter mile or less) as a Bike Route, has three-to-four-foot-wide shoulders, and has the old 16-inch-wide rumble on the fog line all the way to I-40 at Lebanon. At the Dekalb county line the shoulder and the Bike Route disappear, but the rumble does not. It continues through
The 16-inch rumble application north of Watertown is barely manageable for a cyclist until near I-40 where the shoulder widens to about ten feet. The 8-inch November grooving is on shoulders 4-to-6 feet wide and presents no significant issue for cyclists. It has frequent non-grooved gaps. In Dekalb county the road has no shoulder and if the bicyclists choose to ride here (highly hazardous for bicycle use) they must ride in the roadway with high speed (at least 55MPH) regardless of the presence of the rumble.
