A modern notice board on Tay Street outlines the history of the Bridges of Perth. It is Panel 3 of the Perth Medieval Trail entitled Crossing the Tay and replaces an earlier board (also pictured). A little further south along Tay Street is another board (Panel 2) entitled Soggy Feet which explains changes in the ground level of Tay Street over history.
At the gateway to the Memorial Garden, on the North Inch, there are two plaques, one on each side of the entrance. The left -hand side shows present Perth Bridge, the right-hand side shows the Old Perth Bridge. By comparison the new bridge has fewer arches each of which is higher and wider than in the Old Bridge. The Old Bridge being lower and the arches narrower it is clear there was a greater possibility of debris brought down by the river in flood could form a dam, which would cause the bridge to collapse.
