History
The August 1966 resolution authorizing construction of I-35W in McPherson County also authorized a connection from the new interstate to Lindsborg from the south. The initial resolution declared that this route would carry the designation of K-155.
However, several months later, in March of 1967, the Highway Commission elected to change the designation to US 81. The designation change was pencil-noted on the resolution, and the new segment of state highway was opened as US 81 when I-35W was opened in 1969.
In 1981, the Lindsborg connection was re-designated US 81B and in 2009, the route was turned back to McPherson County.
