History of King's Highway 42:

King's Highway 42 was a minor collector highway which connected Highway 29 at Forthton to Westport. The highway was 53 km in length and it existed up until the late 1990s, when it was downloaded to the County of Leeds & Grenville. The history of Highway 42 dates back to 1935, when the Department of Highways assumed the Forthton-Westport Road as a new King's Highway. Most sections of Highway 42 were already paved when the highway was assumed in 1935. The only gravel sections were between Delta and Crosby and from Newboro to Westport. However, these gravel sections were paved during two highway improvement projects that were carried out in 1945. Originally, Highway 42 ran concurrently with Highway 29 for approximately 16 km between Brockville and Forthton. This concurrent designation existed up until 1983, when Highway 42 was truncated at the Highway 29 Junction at Forthton. During 1983, the length of Highway 42 was reduced from 69 km to only 53 km.

On March 31, 1997, the entire highway was downloaded. The road is now officially known as Leeds & Grenville County Road 42, although the road is still often referred to as "Highway 42" by motorists. Services are available in most communities along the highway. Unless posted otherwise, the speed limit on Highway 42 is 80 km/h (50 mph).
