Remnants of the first bridge over the Nepean River. According to local historian Arthur Street, the remains of the bridge were buried under boulders for nearly 100 years. In the mid 1940s they were uncovered by local schoolboys from Penrith Public School. While there were suggestions the remains were from an old railway line used by Blue Metal Quarries, Street deemed them to be the top decking of a bridge. After a flood in the late 1940s, the remnants were covered up again or washed away.
