The road did not go from Moncla to effie as you show it, the original road curved from aproxamatly 1/2 mile away from the river to the river and the bridge was built in a curve to reach the other side. if you go to the site from Moncla , as you come to the end of the main road you will see the road banks left in a curve, follow that curve to the river, i used to go and sit on the old road when i was a kid at the river.

I have to wonder if "Big Red" after almost 75 years is now mounting an attack on the remaining bridge approach. It's getting awfully close to the Effie side.

The 4 pictures in my previous post didn't come in at the order that I thought, but you can probably figure out which is which. I'm posting better picture of the old approach.

The man in Marksville told me about the last two vehicles to cross the bridge. Two men were discussing going across from the Effie side. One was driving a log truck and he insisted that he definitely had to get across the river. The other driver decided to follow him even though the bridge had been condemned and closed. The bridge was shaking to beat the band frightening both men, but they did get to the other side just before the bridge collapsed. It was seconds later that it went into the river.

I have to wonder if they had removed a barricade. A man and woman perished because they apparently didn't know the bridge was closed.

I took a road trip to Marksville for a number of reasons, and I did pay a visit to the old bridge site. Attached are several photos. I was able to view some of the archives at Marksville Weekly News. In 1995, there was a 50-year bridge celebration where some of the old timers shared their memories of the event. If there is a 75-year celebration in 2020, I'll definitely plan to be there.

The replacement bridge opened in 1949, not 1947 like some online info indicates. I knew '47 had to be wrong because I remember riding the ferry at the original bridge site. I was born in late '47.

The gentleman at the Weekly News mentioned that the engineers for the replacement bridge (now demolished) and the current bridge were father and son. If I remember correctly, it was the grandson who pushed the button that brought down the replacement bridge.

Two of the attached photos are of what remains of the original bridge. The traffic lanes were less than 10 feet wide. The view with the 3 trees is toward 1196 on the Effie side. The other view is toward the Red River although you can't see it. Another photo shows swing support still in place in the river. The fourth picture is of the sign at the site which has a brief spiel about the original bridge. They put a picture of the wrong bridge on the sign. That's the replacement (now demolished).

Although I was very very young at the time, I distinctly remember being with my folks crossing on the ferry. I only remember the crossings in one direction - never toward Effie even though we obviously did go that way.

I also distinctly remember the words used by my dad when his 1940 Ford died going up the ramp on the Moncla side.

Newspaper reports state that two 40 foot spans collapsed on April 11th, 1945 due to floodwaters. These were on the Moncla side of the river as you approached the steel swing span. The bridge was never repaired. A ferry was used to cross until a newer bridge was built up river.

Did the first bridge fail, or was it replaced by the Long-Allen bridge that we used up until the 90s? I'd like to know more about this bridge.

Here is a modified satellite image that shows the most likely original highway/bridge alignment based on 1940s Parish and USGS maps. Concrete slabs and approaches are in red. The black lines represent the location of the steel bridge spans. The river was much narrower and approached the bridge at about 90 degrees when it was built between 1931 and 1934. The pier for the swing span still exists as well as a small concrete approach opposite the Moncla side of the river.
