History of Secondary Highway 506:

Secondary Highway 506 was a local highway in the County of Frontenac that provided access from Highway 41 to the community of Plevna. Highway 506 was first depicted on a Preliminary Route Plan prepared by the Department of Highways of Ontario (DHO) in April 1956 and was designated by an Order-in-Council dated May 9, 1956. Highway 506 extended east from Highway 41 north of Kaladar for approximately 21 miles (33 km) to Plevna. Provincial jurisdiction over Highway 506 ended on Lorraine Street at the eastern entrance to Plevna. A bituminous prime surface was laid along Highway 506 in 1956. The sections of Highway 506 lying between Highway 41 and Myers Cave and from Plevna westerly were paved in 1964-1965. The balance of the highway was paved in 1969. Extensive reconstruction of the original highway's route took place east of Myers Cave between 1979 and 1981, with many of the old highway curves removed as the highway was straightened. Highway 506 remained in the provincial highway system up until the late 1990s. Jurisdiction over the highway was transferred from the province to the Township of North Frontenac, effective January 1, 1998. Former Highway 506 is now known as North Frontenac Road 506. Unless posted otherwise, the speed limit on Highway 506 is 80 km/h (50 mph). Services are available on Highway 506 in Plevna and in nearby Cloyne along Highway 41.
