The Pimple
The double decked road/rail Grafton Bridge over the Clarence River in northern New South Wales was opened in 1932 concurrent with the standard gauge railway line from Sydney to Brisbane. It's a classic bridge of the era but has a bascule, lifting section which was controlled from the little pimple box that hangs off the upstream side and shown in this photo. The bascule feature is no longer used as larger vessels no longer head inland. The bridge also has two sharp bends in the road on the upper deck to allow it to take up its position on and off the bridge above the railway tracks.
The link below gives a good history of both the now two Grafton bridges and other backgrounders to this important and fascinating city.
