As for the 172 and the Pape diversion in general, the truly annoying feature was that it was so prominently advertised in King and St. Andrew Stations while information about the 509 Harbourfront bus (a much more frequent and well-used service, especially by people unfamiliar with the area) went for a long period with only minimal signage. Visitors from other planets might be forgiven for thinking that 72 Pape / 172 Cherry are vital routes without which the city would collapse.
