History of King's Highway 7B (Carleton Place):
Highway 7B through Carleton Place was created out of route renumbering in the early 1960s. Originally, Carelton Place's Business Route was known as
Highway 15B. In 1961, Highway 15 was rerouted between Smiths Falls and Carleton Place and the old route of Highway 15 between Perth and Carleton Place
became Highway 7. This resulted in the renumbering of the Carleton Place Business Route, from Highway 15B to Highway 7B. During the 1970s, the routing of
Highway 7B was shortened. Rather than return to Highway 7 via Franktown Road, the highway was truncated at Highway 29 (later renumbered as Highway 15).
This took place sometime between 1970 and 1977, but the exact year is not known. In 1994, a new Highway 15 Bypass was opened along the eastern edge of
Carleton Place. This new route bypassed downtown, so Highway 7B had to be extended easterly along Townline Road for another 1.1 km, to meet up with the
realigned Highway 15 at McNeeley Avenue. On January 1, 1998, Highway 7B was formally decommissioned. The former highway is now known as Lanark County
Road 7B and Townline Road.
