This classically configured concrete arch crosses Neenah Creek just east of Oxford.
The structure was built in 1910 during the construction of this line.
The structure can be accessed by following footpaths from the UP 1st Court Bridge
While it is built for a single track, the north end makes it possible to expand to a second track by using a stepped endwall. It looks like this never happened.
