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?
