King's Highway 49, commonly referred to as Highway 49, is a provincially maintained highway in the Canadian province of Ontario. The 5.8-kilometre (3.6 mi) highway travels across the Quinte Skyway and through the Tyendinaga Mohawk Territory south of Marysville. The route remained unchanged until the late 1990s, when more than half of the highway was transferred to the jurisdiction of local governments. The Quinte Skyway, as well as the portion through the Mohawk territory were retained in the provincial highway system, resulting in Highway 49 not connecting with any other provincial highway.
