Kentucky Route 67 (KY 67) is a Kentucky State Highway originating at a junction with Interstate 64 (I-64) near Grayson, Kentucky in Carter County. The route continues through rural ridgetops in Greenup County and briefly touches Boyd County before terminating at U.S. Route 23 (US 23) in Greenup County in between Wurtland and Greenup. KY 67 is also known as the Industrial Parkway. Route description KY 67 lies within the Ohio–Kentucky Carboniferous Plateau, a hilly mosaic of woodland, pastureland, and cropland. The highway begins at a trumpet interchange at I-64 east of Grayson southwest of the Carter–Greenup–Boyd county tripoint. At the north end of the interchange, KY 67 leaves northeastern Carter County and enters southeastern Greenup County. The highway crosses over Logtown Road and intersects EastPark Drive, which serves the south unit of the eponymous business park. KY 67 enters the western fringe of Boyd County, within which the route crosses over Addington Road before re-entering Greenup County. The highway intersects Technology Drive, which serves the north unit of the business park, including a campus of Ashland Community and Technical College. KY 67 follows a ridge between the headwaters of multiple creeks; in this area, the route crosses over Culp Creek Road and Pleasant Valley Road; access between the highway and the overpassed roads is via connector roads. The highway descends into the valley of the East Fork of the Little Sandy River and has a four-ramp partial cloverleaf interchange with KY 207 (Argillite Road). KY 67 crosses over Horn Hollow Road, which the route accesses via a connector road, before curving east and then north along Deer Hill Branch to descends from the hills to the floodplain of the Ohio River and enter the city of Wurtland. At the bottom of the hill, the highway intersects US 23 immediately before reaching its northern terminus at KY 3105 (Wurtland Avenue). The Kentucky Transportation Cabinet (KYTC) classifies all of KY 67 in the state primary system. KY 67 is part of the main National Highway System for its entire length. History Construction began on phase one in the spring of 1997. The first segment of the Industrial Parkway extended a little over three miles (5 km) to a new industrial park. A trumpet interchange was constructed at milepost 179 on Interstate 64. Along the Parkway are two at-grade intersections for this segment, both of which can be upgraded to full folded-diamond
