On Highway 420.
The concession system was laid out as a grid system for land development, perpendicular to lakes or rivers, 100 chains apart (10 square chains to an acre). Each county has its own system for numbering townships' concession roads, including having opposite numbers on the same road (even one side, odd the other). Photo courtesy Doug Kerr.
Cool gantry on Highway 406 NB - but miserable exit signage. No, RR 77 is not a left exit. No, all roads do not lead to Fourth Avenue. In fact, this is Ontario's way of saying that the two right lanes exit... it might help if the name of the exit were on the right of the arrows, since the little straight stub can be confusing. In the states, of course, you'd see an EXIT ONLY over the right lane with an arrow over the left, or a better diagrammatic than this.
