Ontario Highway 17A (Thunder Bay) History - The King's Highways of Ontario

King's Highway 17A served as an alternate route to Highway 17 between Port Arthur (which later became part of Thunder Bay) and Sistonen's Corners. The highway was first assumed as a new King's Highway by the Ontario Department of Highways on June 30, 1937. The highway was 36.3 km long. In 1938, Highway 17A was paved from Port Arthur to the Dog Lake Road turn-off near Intola. The balance of the highway from Intola to Sistonen's Corners was paved in 1964. In 1959, Highway 17A was co-designated with Highway 11A for its entire length. In 1972, both Highway 11A and Highway 17A were renumbered as Highway 102. A different, unrelated Highway 17A has existed near Kenora since 1990.
