Concrete Tank Traps were built during WW2 to span a bottle neck in the Clarence River Valley, east of Tenterfield in northern New South Wales, in an area known as Paddys Flat. The concrete pillars are still visible in and beside the river near the crossing.

It has been suggested by some that these Tank Traps were part of the so-called "Brisbane Line" defence plan. There are some other well known tank traps just north of Tenterfield on the Bald Rock Road. They consist of log pillars and a concrete wall in the valley. The sign posts on the road suggest that they formed part of the so-called "Brisbane Line" defences. The actual existence of the "Brisbane Line" is still very much open for debate. The tank traps are about 1 km north of London Bridge where there was a large army camp during WW2. There was up to 10,000 soldiers camped in the Tenterfield area during WW2.

The timber tank traps near both the Mount Lindsay Highway and the Bruxner Highway are of similar construction approximately 4 rows of wooden posts, evenly spaced. The one near the Bruxner Highway have been badly fire damaged in recent years.

tanktraps06.jpg (43684 bytes) Tank Traps near the Bruxner Highway approximately 27.5 kms from the outskirts of Tenterfield, on the way to Casino. They are not sign-posted. They may be an extension of the line of tank-traps extending from the Mount Lindsay Highway which is not that far away. (Photo - Bill Durrant)

tanktraps08.jpg (52883 bytes) Tank Traps near the Bruxner Highway. The tank-traps on the left-hand side of the road are not visible, unless you get out of your car and look down over the side of the road. They extend for approximately 70 metres. The tank traps on the right-hand side extend up and over the crest of the hill and partly down the other side. Approximately 150 metres in length overall, for the uphill section. A small section has been bull-dozed. (Photo - Bill Durrant)
