Located north of Morning Sun, this exceptionally unique stone arch bridge crosses 40th Street and a branch of Honey Creek.
Built in 1886 to replace an older trestle, the bridge features a pair of stone arch spans. The larger and southernmost span crosses 40th Street, while the northern and smaller span crosses the creek. The bridge was designed by Elmer J.C. Bealer, and the stone quarried at the Cedar Valley Quarry.
Double arches are common, but this configuration is the only one seen like it. Locally known as the double decker bridge, the northern arch is actually parallel but below the southern arch. A box like structure allows it to stick out on each end, underneath the wing wall of the larger arch.
The larger arch was lined with a small pad of concrete to protect it from deterioration. The smaller arch has currently seen only a small lining along the bottom of the wall. Unfortunately, trees have begun to grow in the box structure on the east face.
As reported at multiple sources, this bridge carries the Hoover Nature Trail over 40th Street. However, GIS maps show that this bridge is privately owned. As Louisa County continues to negotiate for more of the former railroad corridor back, it is likely that this will become part of the official Hoover Nature Trail.
40th Street also does not show up in official county maps, indicating a likely private status as well. However, the author has decided to list the bridge as being a trail, as both Louisa County and rail-trail sites consider the bridge as such. It seems likely that the bridge would be privately owned. However, if the bridge is posted, one visiting should respect private property.
Overall, this bridge appears to be in good condition, with little significant deterioration. However, tree removal to preserve the structure is a must.

The author has ranked this bridge as being regionally significant, due to the exceptionally unique adaption of a double stone arch.
