History
When I-70 was completed through WaKeeney, a segment of 13th Street from the junction with US 283 south to I-70 was brought into the state highway system as a spur of US 283. By 1984, this segment, along with US 283 from 13th and Barclay to I-70 at exit 127, was designated as Buisness 40.
Despite the designation, the route may have not been signed as a spur of US 283. Photos from Michael Summa dated 1986 posted at Steve Alpert's Alps' Roads indicate that the US 283 spur was marked as a Business loop of I-70.
