- I join the on ramp from Sylvan Avenue.
- About 150 metres (estimated) along the on ramp a sign indicates Open Road and means that the maximum speed that you can travel at is 100km/h.
- Another couple of hundred metres later you get a warning that an 80km/h zone starts in 300 metres.
- The 80km/h zone (which is actually practically far less than that about 6 hours a day due to traffic!) begins.
Why not just go from 50km/h to 80km/h?
