The cycle path is shown as not connections here. You can cycle across the bridge, the red footpath to the car park immediately to the East is a shared footpath/cycle path. If you plot a cycle trip from here to Dundee (or Leuchars to Arbroath for example, it takes you via Perth right now instead of across the Tay Road Bridge cycle/foot path in the centre of the bridge. Anyway is because this tiny bit here is shown as a footpath only which it’s not.
