Murray Bridge Speedway
During the mid-late 1980s and through most of the 1990s this saw most of the top South Australian drivers based at Adelaide's 430 metres (470 yards) long Speedway Park rarely race at Murray Bridge.In order to do this the track was lengthened and widened to its present 360 metres (390 yards) length with 6° of banking, and clay was added to the dolomite surface.During this time the pit area (located outside of turns 3 & 4) was enlarged to be able to house more cars for the expected championship and high-profile meetings of the future.Until approximately 2007 Riverview also had a smaller, 130 metres (140 yards) junior track (also made of dolomite) for Under-16 speedway riders on its infield from the early 1980s.New South Wales based rider Darrin Treloar and his Murray Bridge-based passenger Jesse Headland won the World championship.
