Highway14 was one of the original provincial highways created by the Department of Public Highways (DPHO), predecessor to the modern
Ministry of Transportation of Ontario (MTO), in order to qualify for funding under the Canada Highways Act. Two roads in
Eastern Ontario, the
Belleville–
Picton road, and the Foxboro-Belleville Road, were assumed by the DPHO on May18, 1921. It was designated as Highway14 during the summer of 1925. Most of the road was paved by 1925; the last gravel sections – south of Belleville between Bloomfield and Prince Edward County Road4, and between Mountainview and Rossmore – were paved in 1926. At this point, the road was in length. The Department of Highways took control of several roads though the townships of Thurlow, Sidney, Rawdon and Marmora on April18, 1928, extending Highway14 north to Highway7 in the village of Marmora. This brought the length of the route to . The new portion of the highway was entirely unpaved when it was assumed. Paving began in 1937 through and northwards from Stirling, with the first to the hamlet of Harold being completed that year. The remainder, between Harold and Marmora, was paved the following year. The final unpaved section, between Foxboro and Stirling, was completed in 1940. A bypass was opened around Foxboro in late 1963. The
Norris Whitney Bridge over the Bay of Quinte, south of Belleville, was opened in December 1982, replacing the original 1891
swing bridge. Portions of the original causeway can still be seen alongside the current structure. Shortly thereafter, by 1984, the section of Highway14 south of Foxboro to Highway33 at Bloomfield was renumbered as part of Highway62. The length of the highway was now . alongside the
downloading of
Highway 33 and the portion of
Highway 2 within Hastings County. The road became Hastings County Road14, but the County of Hastings then downloaded the county road (and the responsibilities of its maintenance) to its constituent
towns and
townships on January1, 1998. Since 1998 the road has been known as Stirling-Rawdon Road14, and Marmora & Lake Road14. == Major intersections ==
