K-108 (Kansas highway)

K-108 was a 1.500-mile-long (2.414 km) north–south state highway in the U.S. state of Kansas. Both of K-108's termini were at U.S. Route 59 (US-59) on the west edge of Erie.

Before highways were numbered in Kansas there were auto trails. A portion of K-108 followed the former King of Trails. In 1946, a new alignment of US-59 was approved to the west of Erie, as well as K-108, which would connect Erie to the new alignment. The new alignment of US-59 and K-108 were completed in 1960. That same year, K-108 was extended east, then north, then west to US-59. This created a complete loop through Erie off US-59. K-108 was removed from the state highway system in a resolution approved in 2004.
