Ontario Highway 74 History - The King's Highways of Ontario

King's Highway 74 was a short collector highway which linked New Sarum, Belmont and Nilestown to Highway 401 near Dorchester. The highway was 22 km in length and it existed up until the late 1990s, when it was downloaded to the Counties of Elgin and Middlesex. The history of Highway 74 dates back to 1937, when the Department of Highways assumed the county road from New Sarum to Dorchester Road (known as Hamilton Road today) as a new King's Highway. Contrary to popular belief, Highway 74 did not connect directly to Highway 2 during its 60-year history, even though Highway 2 existed only a short distance to the north of Nilestown. Highway 74 and neighbouring Highway 73 are both strange anomalies of the Ontario provincial highway system, in that these two King's Highways ended at a county road junction and not at a provincial highway junction.

Highway 74 was entirely gravel-surfaced when it was first assumed. The highway was paved between Belmont and Nilestown in 1938. The balance of the highway from New Sarum to Belmont was paved in 1952. The entire highway was downloaded on March 31, 1997. The road is now officially known as Middlesex County Road 74 and Elgin County Road 74, although the road is still often referred to as "Highway 74" by motorists. Services are available in most communities along the highway. Unless posted otherwise, the speed limit on Highway 74 is 80 km/h (50 mph).
