Signage in Lampasas shows the elimination of US 281 Truck, with mainline US 281 being routed over the former truck route, and the creation of a new US 281 Business on the former alignment of US 281. Signage is updated to reflect these changes at all three intersections of the "triangle." See the diagram below for a Before/After.
