State Route 185 (SR 185, OH 185) is a 21.70-mile (34.92 km) long east–west state highway in the western part of the U.S. state of Ohio. The western terminus of SR 185 is at U.S. Route 127 (US 127) approximately 3.75 miles (6.04 km) south of North Star. Its eastern terminus is in Piqua. Until 2011, this was at its junction with US 36 and SR 66 in the city's downtown business district, at the intersection of Ash Street and Spring Street. In 2011, SR 185 was re-routed to travel south along Sunset Drive in the western part of Piqua to a new eastern terminus where Sunset Drive meets US 36, which is known as Covington Avenue at that location.

Route description

Along its way, SR 185 travels through eastern Darke County and northwestern Miami County. No portion of this state highway is included as a part of the National Highway System (NHS). The NHS is a network of routes deemed to be most important for the economy, mobility and defense of the nation.^[6]

History

SR 185 was applied in 1940. Replacing what had been designated SR 120, the highway ran from its intersection with Greenville–St. Marys Road (County Road 98, CR 98), at the time a part of US 127, to what was, until 2011, its eastern terminus in downtown Piqua at the intersection of US 36 and SR 66.^[1][2] By 1953, when US 127 was re-routed onto a more direct alignment in northern Darke County, SR 185 was extended a short distance west to its current western terminus at the then newly-realigned US 127.^[7][8]

On September 26, 2011, SR 185 was re-aligned from its former eastern terminus at the junction of US 36 and SR 66 in downtown Piqua. The new route travels south along Sunset Drive from the intersection of Park Avenue, and ends where Sunset Drive meets US 36 (Covington Avenue).^[9]
