Kentucky Route 189 Wikipedia
KY 189 starts at an intersection with KY 507 in rural western Todd County between Allegre and Pilot Rock. It enters northeastern Christian County about two miles (3.2 km) from the beginning. It passes through the communities of Fearsville and Fruit Hill and has intersections with KY 107 and KY 800 in that area.
KY 189 then crosses the Pond River into Muhlenberg County. It intersects U.S. Route 62 (US 62) on the west side of Greenville and parallels US 62 from there all the way to the routes current northern terminus at another intersection with US 62 just southwest of Central City and north of Powderly.
At one time, KY 189 ran concurrently with US 62 from the second junction between the two routes and Central City. KY 189 had also bypassed Central City to the west and ended at a junction with US 431 in South Carrolton. That bypass was also designated as the truck route of US 431 and KY 70 on the west side of Central City. KY 189 was decommissioned from the Central City bypass when US 431 and KY 70 were rerouted to overlap US 62 and then turn onto the bypass. Since then, KY 189 has ended at the US 62 junction just south of Central City.
