"Abbotsford Bridge is a steel Allan truss-type bridge spanning the Murray River between Curlwaa, New South Wales, and Yelta, Victoria. It is the only remaining steel truss bridge with a lift span that crosses the Murray. It was also the second last lift span bridge to be built along the river after the Nyah Bridge opened in 1941. It was built in 1928 by the New South Wales (NSW) Department of Public Works and was designed by Percy Allan.
The bridge was originally planned to carry the Mildura railway line over the Murray River and into New South Wales, though the line was never extended to the bridge. The bridge currently carries a single lane of road controlled by traffic lights. Abbotsford bridge was built largely to service significant cross-border traffic relating to the fruit production industry. It was constructed over a three-year period from 1925 onwards; but was not originally planned to take so long to build, as there were delays due to problems with a contractor and industrial action.
In 1931, there was a major accident at the bridge when a paddle steamer clipped the lift span, tearing apart the upper deck of the boat."

The cache is located at the NSW end of the bridge. You could probably drive right up to the cache, but I recommend parking at the provided coordinates. The cache can be accessed from different directions, it's up to you whether to take the direct approach or a stealthier one.
