History of King's Highway 41B:
King's Highway 41B was a short business route that passed through the City of Pembroke. This business route was established in 1963, when a new route for Highway 41
was constructed along Pembroke's western boundary via Boundary Road. The old route of Highway 41 leading into Downtown Pembroke via Eganville Road and Christie Street
became Highway 41B. The business route came to an end at Pembroke Street West & Lake Street (Highway 17 & Highway 62). The entire route of Highway 41B was
considered a Municipal Connecting Link and was thus not under the jurisdiction of the Department of Highways of Ontario (DHO). By the early 1980s, planning was
underway on an improved entrance road into Downtown Pembroke via Olympic Road and Muskrat Drive (today's Paul Martin Drive). Highway 41B lost its Municipal Connecting
Link designation in the early 1980s, when the old business route was supplanted by the proposed new route for Highway 41 into Downtown Pembroke. It is not known for
certain if Highway 41B was still being signed as a King's Highway by 1980, as the route last appeared under that designation in DHO mileage tables dated 1970.
At a length of only 0.8 miles (1.3 km), Highway 41B was likely Ontario's shortest signed King's Highway. While Highway 28A at Young's Point was technically shorter
than Highway 41B, it is not known for certain if Highway 28A was ever actually a signed King's Highway route. Since Highway 28A was simply a bypassed section of road
left behind after a bridge replacement project, it is quite likely that the route of Highway 28A wasn't signed with any route markers.
