Thanks Luke!. glad you corrected.
Dana, the bridge in the streetview/google sphere you added was the northbound PR1 bridge, not the bridge this entry is for.
Yes J.P. you can say this a bridge enthusiasts playground from what i see.
so could we say this is a bridge enthusiasts playground?
I agree, George.
Better turned into a swingset support than melted down (Or worse, an "abstract" art piece.)
Art: Thanks! I ended up coming across the source for a bunch of stuff by accident.
It is too bad that the site isn't international, as there are some impressive bridges around the world.
I had heard of this type before, but really know nothing about it. Totally doesn't surprise me as it looks more girder and less truss.
A very cool structure nonetheless!
Great way to repurpose a bridge i think.
Tony, I can tell you this is a standard European form of metal bridge, and over there they typically call these lattice girders. No idea if that tells you anything about how the engineering functions, but that is what they are known as.
That's one HELL of a swingset!!
Interesting "truss"...which really looks more like a Lattice girder. I would love to see testing on such a span to see the tension and compression compared to a traditional pony truss.
I like the Puerto Rican stuff! Really interesting, especially since it was a Spanish territory prior to 1898!
Its too bad we can't expand the site's scope. I've found info on Keystone and Phoenix bridges 'south of the border'
Recent picture of the bridge.
Here a photo i too a few years ago you can use here.
Here is a translation of the description on this photo:
The Marquis de la Serna bridge named in honor of Felix Maria Messina, who was Governor of Puerto Rico from 1862 to 1865. It was the first metal bridge built on the island, and the only laminated iron arch that exists today. The iron items were brought from France. The bridge is segmented arches are similar to the Arcola bridge in Paris. The structure is located 24 feet above the river level.
The bridge was assembled by Isidoro Abarca, founder of the Foundry Abarca, was mounted on the same anterior bridge abutments built of masonry and wood. Part of the road between Cataño and Bayamón, a major route between the island of San Juan and agricultural lands in the west and south. Between 1881 and 1900, the bridge served as part of the railway train from the west. For this reason, two of the arches strengthened in 1881.
