Business Loop I-135 - Lindsborg

Interstate 135 passes well east of the city of Lindsborg through rural Smoky Hill township. An 8.7 mile long business loop was proposed from I-135 between Exits 72 and 78. The route was disapproved by AASHTO on October 13, 1979, but later designated as U.S. 81 Business. It ran west along Smokey Hill Road (CR 429) and north on 14th Avenue (old U.S. 81) into Lindsborg, where it combined with K-4 (McPherson Street) east. K-4 returned U.S. 81 Business to I-135/U.S. 81 at Bridgeport.

U.S. 81 Business to Lindsborg was subsequently decommissioned by 2014.
