K-129 (1980–1997 Kansas highway)

K-129 was a 0.446-mile-long (0.718 km) state highway in the U.S. state of Kansas. K-129's southern terminus was at K-154 in Dodge City and the northern terminus was at U.S. Route 56 (US-56), US-283 and US-50 Business (US-50 Bus.) in Dodge City.

K-129 was first designated as a state highway in 1980, replacing US-154 Spur. Then in 1994, when US-400 was created, K-129 was decommissioned and became a part of a newly rerouted US-56, US-283 and US-400.
