History of King's Highway 7A (Alt) Port Perry:
King's Highway 7A (Alt) was created in 1944, when a 2.1 km alternate route to Highway 7A was established through Downtown Port Perry. Under a connecting link
agreement with the Department of Highways (DHO), a Highway 7A (Alt) route was signed along Queen Street and Water Street through Port Perry. The connecting
link agreement was dated June 5, 1944. It is not certain how long Port Perry's Highway 7A (Alt) route lasted. The most recent reference to the highway in
a DHO document was dated January, 1963. The route does not appear in the 1963 DHO mileage table, suggesting that the route was decommissioned at some point
during 1963.
