This appears to be a Bailey bridge constructed to replace a bridge washed out in 1972 flooding.

Posted May 3, 2017

This report says the bridge was reconstructed with both original and new parts:

I visited by driving on Rt. 35 last month, and the bridge (which leads only to a round turnaround) was still closed to traffic with construction barricades at the north end.

Not so fast:

http://www.thv11.com/news/local/migratory-birds-postpone-bri...

"The Jonesboro Sun reports that the dismantling of the Black River Bridge, a historically registered landmark, was scheduled for July. But state regulations prevent the demolition of a structure that migratory birds have nested in.

Randolph County Chamber of Commerce Executive Director Tim Scott says the birds were discovered shortly after a bid for the demolition was accepted on March 23."

Correction:

The covered bridge seen in the postcard aerial view is the ROAD bridge, at the site of the present-day highway bridge.

The *railroad* covered bridge is seen only as a short section seen at the bottom right of that view. The railroad continues straight over later-day Fourth Street from that bridge.

As the person who posted all four photos, I should point out that all four photos were secured from cooperative railroad officials, only one of which is willing to be named. Further, the photos from the train are not from a regular passenger train, but from a reward-facing camera riding on a special track inspection vehicle. Anyone attempting to duplicate these photos from a regular Amtrak or MARC passenger train is likely to be very disappointed in the results by comparison.
