Located east of Freeport, this large concrete slab bridge crosses Rock City Road and Wickham Creek.
Built in 1918, this six span concrete slab bridge was built for two tracks. The bridge was built on concrete substructures.
These types of bridge were commonly used to cross creeks and roads. The second track was removed at an unknown date.
Overall, the bridge appears to be in fair to poor condition. Some significant deterioration has begun to show up on the bridge.

The author has ranked the bridge as being locally significant, due to the common design.
