The old railroad bridge northwest of Niobrara provides a walking bridge from Niobrara to the Niobrara State Park. It was built in 1929 as a replacement for a 1902 bridge across the river. It spans the Niobrara River just before it empties into the Missouri. A wood deck complete with rails and benches has been constructed over the entire length of the railroad bridge providing excellent opportunities for fishing, birdwatching, and nature enthusiasts. The bridge is registered in the National Register of Historic Places.
