The railroad built two embankments through this valley that has a small, intermittent stream that joins Hill Creek. The earlier northern one was abandoned when the southern one was built. The stream and Old Pearl Road, or Township Road 461, share the stone arch culverts, or tunnels. At the culverts the two embankments are approximately 230 ft (70 m) apart. In between the embankments is a cave that is part of the Twin Culverts Cave Nature Preserve.

KCS - Twin Tunnels

What year were the twin culverts constructed?

I'm not sure what to do with the dimensions for this one.

These are effectively tunnels, making the "bridge" actually for the railroad. So the span would be 10 ft. But from the perspective of the road, they are 50 ft long.

So what values should I put in the "deck width" and "span" fields?

Also, there are two structures on two different railroad embankments about 230ft apart. Should they be listed separately? Should the location be an average between the two?
