This is on old US 71 north of Mena. Could it have been replaced by the county using whatever they could acquire? Or is there an actual reason to build a bridge this way?
That bridge is simply a pony truss with concrete approach spans. I know it well as I grew up in Mena.
Here's a pic of the other end. Note the concrete on the right side of the bridge.

For some reason i think it used to be two pony truss spans, and one was removed.
After WWII (and with the Korean conflict too) materials were in short supply, and if a county had to take out a bridge somewhere, it wouldn't neccessarily go to the scrap yard. Many were repurposed to other sites, like on a busy county gravel somewhere. A state highway bridge, even if functionally obsolete, could still provide useful service elsewhere, on a secondary road for instance. Or a short highway bridge might become an approach span for a larger bridge elsewhere
I recall my dad buying a bridge the county replaced with a 9' culvert. We used it for many years, reassembled on our farm. It was cheap, too, the 7 I-beams costing less than $300. We have since replaced the bridge with a tube, and some of the beams are now built into a small bridge in a nearby park.
Even railroads do this. The original 1880s 330' spans of the C&NW span over the Missouri River at Blair weren't scrapped in the 20s, they were disassembled and moved to Wyoming. IIRC, they were rebuilt shorter, so the weight limitations that made them obsolete at Blair weren't a problem at their new location. Recall re-building a bridge at half it's original length can increase it's load capacity by more than double.

There are many examples of this in the old Arkansas minute orders (it stopped, at least temporarily, when the state system was expanded in 1963).
Quote[July 1963]
5141 WHEREAS, by Minute Order No. 4063, dated April 4, 1961,
the Commission established a policy for the disposition of old steel bridges that are being replaced with modern design bridges, and,
WHEREAS, this policy provided that under certain criteria the County Judge in the County in which the structure is located would be given the option of utilizing such old structure, and,
WHEREAS, the State Highway Commission has recently added to the State Highway System approximately 800 miles of County roads on which are many unsafe, dilapidated bridges in need of immediate repair, in order to carry traffic, bridge steel salvaged from these old bridges would be of great benefit to the State Highway Department in the repair and reconstruction ofsecondary bridges and culverts,
THEREFORE, it is the order of the State Highway Commission that all salvaged steel from old bridges remain the property of the Highway Department for exclusive use on the State Highway System.
Any provisions of Minute Order No. 4063 contrary to this order are hereby rescinded.
I was wondering if this bridge was such a case. But the bridge on the new alignment was built in 1965, so unless they resumed the program the old alignment would have been a state bridge while the program was in operation.
Steve Gum: The concrete spans are definitely original because there's a bridge just east of this one over a relief of the Ouachita River that has the exact same style of railing that appears to be exactly the same age.
Isn't it possible that the pony truss span was placed at this spot later, replacing another original span with concrete railings?
Virginia built lots of bridges like this in the 1920s-30s...
Here are both ends of the now-destroyed VA 94 bridge over the New River built in 1927:

Virginia did take late 19th century and early 20th century bridges and move them around to other locations but I don't recall ever seeing anything to suggest they were removing truss segments and replacing with concrete railing. Virginia also stopped using metal date plates for a few years around WW2 and carved the dates instead for I assume metal conservation reasons.

I guess it's possible but I've never heard of anybody doing that to this bridge. Since the truss is longer than the concrete spans it it has been modified then a pier would have been removed. Next time I'm down that way I'll check to see if there are any remnants of a removed pier in the river.
Ah, the distance between piers explains it. No need to check.
Not a road bridge, but the former New Haven Railroad bridge (http://upload.wikimedia.org/wikipedia/commons/thumb/c/ca/IMG_3976_New_York%2C_New_Hampshire%2C_Hartford_rail_bridge.jpg/800px-IMG_3976_New_York%2C_New_Hampshire%2C_Hartford_rail_bridge.jpg) in Montague, Mass.:

One Whipple truss survived the wooden Montague City Covered Bridge coming off its moorings in the 1936 flood, floating downstream, and knocking the other two trusses into the Connecticut River. The two Warren trusses were built to recomplete the bridge.
Eastbound, covered bridge. Westbound, stone (though relatively new).

I saw a picture of a covered bridge with a single steel through truss span at one end.
Bello Street Bridge (Old Hwy 101 and Old Hwy 1) in Pismo Beach, California. I have walked on it and some parts of it is ready to fall apart.
Built in 1913. Scheduled to be demolished by City of Pismo Beach in the future.

To me this looks like one, an overpass that is also a cable stay bridge on the ends. It looks like they widened the road and just put the cable stay bits on to reuse the existing overpass.

Why can't they rehabilitate it for use as a pedestrian bridge? I don't see any damage that isn't fixable.

Oh, that fucker. IT was the first thing I thought of when I saw the thread. That's on I-55/70 just west of I-255. Currently, it appears to be closed to traffic. I have no idea why IDOT District 8 decided to do the redneck thin instead of just replacing it outright when the I-255 ramps were added under it.

Idot was trying to be creative for a change, versus just tearing it down and replacing it with something even less intersting.
I think it was a bad idea, but I'm still glad they did it. It's awesome, in a screwed-up way.

Given the redneck nature of the bridge, I'm shocked not to see duct tape holding it together.
1920s truss on piers that date to the 1800s (not sure the exact year since the original rail span was rebuilt several times between 1806 and when these were made.)

I recall having to direct traffic from MO96/Historic US66 onto a side road on account of a motorcrash between Old US66 and MO266 about seven years ago as I was coming home from a work assignment upstate. I had to be careful where I sent heavier trucks on account of a very weak and very old one-lane 15mi/h bridge with an eight-tonne load limit. I spent about half an hour directing traffic, mostly onto Old 66 except for heavier trucks which I sent down a lettered secondary route toward Mount Vernon, until a firefighter arrived to take over the detour tasks...That bridge is great for cars and pickups, but if you are driving something heavy, forget it.

The I-5 overpass over WA-20 in Burlington, WA.
It started out being built in 1955 as twin 2-lane overpasses, then widened into one bridge in the mid-70's to accommodate on- and off-ramp lanes.

The long bridge over the potomac river in DC was built in 1903 with girders from the lower trenton bridge (now the trenton makes bridge) with a center swing truss span. In 1943 they removed the trenton bridge side spans and replaced them with new girders.
I found the original plans for the old US 71 Ouachita River bridge.
Here is the link to a PDF file with the plans (https://www.ardot.gov/wp-content/uploads/2020/11/01192-Ouachita-River-Bridge-Acorn-vicinity-current-16218.pdf) for the bridge. It proves that the bridge was built as-is and wasn't pieced together at a later time. It's just an unusual and possibly unique bridge.

Sadly the story is kind of not as cool as it looks on the surface. The only parts of the original spans in use in the 21st century are the piers.
