This 1940s color documentary advertisement about suspension bridges is produced by the American Bridge Division of U.S. Steel, American Steel & Wire Division. The camera pans up from a stream to show a suspension bridge high above (:25-:35). Shown are a stone bridge, bridge arches, and covered bridges (:36-:49). A drawbridge closes (1:55). Pittsburgh has many bridges (2:13-3:08). An animation shows suspension bridges can be anchored into the water (typical) or self-anchored to the road (3:09-3:39). The bridge crossing the Monongahela River is the typical construction, with tower piers and main cables of parallel wires draped over the towers and from cable bands at spaced intervals (3:40-4:10). The bridge spanning the Allegheny River is self-anchored with links and suspenders of forged steel I-bars (4:11-4:44). Men in hard hats carry preformed bridge strand cables to make the Paseo Suspension Bridge. The strands are pulled off giant reels and lifted by pulley to a man on the top of a girder. Filler strips keep the strands perfectly parallel to each other while sockets are locked. The wires are pulled to a predefined tension (4:45-7:43). A simply hydraulic compacting device squeezes the cable to its final size and shape. The cable is temporarily banded and marked to show where it is to be attached (7:44-8:03). Two bridge construction workers wear safety lines while they straddle banded cable high in the air. Another group works off a large moving scaffold hung from wooden rollers (8:04-8:35). A bridge suspender rope is swung to a worker. The sockets on the ends of the suspenders are fitted into their seats on the girders beneath the roadway and secured by bolts (8:36-9:00). The wire wrapping machine is shown in operation (9:06-9:22). Red protective paste is applied (9:28). Splicing two spools of wrapping wire is shown, followed by the wrapping machine (9:38-10:00). Diagrams with interjected pictures of the bridge parts and blueprints for the Delaware Memorial Bridge are shown (10:24-11:28). The construction of the steel towers are diagrammed. To build them required catwalks of cyclone chain-link fencing and wooden cleats to be built over the water (11:30-13:48). Workers on the catwalks work on the tramway system for the spinning cable wheels that move the cable to another location to be attached. Wheels with cowbells attached as warnings pass each other on the lines (13:49-16:00). Counterweights maintain the tension (16:08). Splicing is diagramed (16:23-16:40). The large cable reels are transported by truck and barges and hoisted up. Cranes load the reels (16:42-18:04). The cable continues to be moved by the wheels laying down the wires. Cable bands are applied and coated (18:17-19:33). An animation shows the trusses are built outward at the same time. The process is shown, including men on girders attaching the meeting ends and working on the diagonals and bolts (20:10-24:40). A wrapping machine covers the cable and a protective paste applied (24:42-25:23). The entire suspension bridge is panned (25:27-26:00). The finished Delaware Memorial Bridge with its toll booths and traffic are shown (26:25-27:08).

Red lead paint and good American steel coupled with world class engineering and skilled tradesmen are the reasons that these bridges are still standing today.

That and continuous maintenance. Sadly the lack of proper maintenance is going to cause many to meet a premature end.

Here in New York City, there were many bridges across the East River including the Brooklyn Bridge, the first suspension bridge opened in 1883, and then the Williamsburg Bridge opened in 1903, the first suspension bridge to carried vehicles, walkway and subway trains, and then, the Manhattan Bridge, opened in 1909, the first bridge to have two levels, along with subway trains on each span, and the Anchorages is still majestic with 6 columns and an arch which is a pavilion. The next one is the George Washington Bridge opened in 1931, the Triborough Bridge (aka RFK Bridge) opened in 1936, Bronx Whitestone Bridge opened in 1939, Throggs Neck Bridge opened in 1961, and finally, the Verrazano Narrows Bridge opened in 1964.

My Grandpa told me that 12 workers were killed building the Verrazano Narows bridge. Thanks for the history lesson.

When I was attending Pittsburgh Art Institute in the early 1970's, I walked across the Sixth Street Bridge, crossing the Allegheny River, many times per week. The classes visited the Planetarium and various museums for art inspiration. Although, not talked about in this film, I also rode the Mount Washington Inclines many times also.

I retired from USS in Pittsburgh after 35 years service. Made a good living for my family and a comfy retirement to enjoy now. Dirty and hot, though. lol

Fantastic film! The Delaware Memorial Bridge is about an hours drive from my present house. Use to go over it years ago when I was in college in Maryland.

And then, they built the same bridge as it was before, and turned into a double bridge, and it also opened in 1968, but this short was made in 1951 which was after the bridge opened.

Bad jump cut at 2:02 and missing the narration at 2:03 of what he was saying. And then a bad jump cut at 2:08 where he was saying “The Pittsburgh of...” What? The narrator was missing the point that the three rivers including Ohio, Monongahela, and Allegheny rivers meet to flow westward of Ohio was the Pittsburgh of...” Rivers? Or was it?

"Safety first" but not many harnesses used. These guys would die if they fell. How long did it take people to understand that someone would die if they fell and how easy it is to make a harness?

I have to say, the Audio is pretty horrible after the 4:00 mark. But, I Donned my Headphones and Marshalled on! (despite the LOUD advertisements). I was surprised to see a Kansas City, Missouri bridge featured; The Paseo Bridge. I always wondered why it was replaced so Early in it's lifespan, now I now "Why"... the crews used Aluminum Filler Wire and other Aluminum Pieces, which came in direct contact with the Steel Wires, thus creating Galvanic Corrosion. Sad, because the Paseo Bridge was truly Beautiful!

I have built about 15 bridges in my life, mostlu ILM, cable stay, stressed-ribbon.. but never a suspension bridge.

@365Condoms 2 жыл бұрын

there is a mistake in the videos. he keeps calling the cables "they are pre-stressed in the factory".. that is incorrect. it's either post-tensioned after the pour or pre-stressed while in the formwork.

I wonder if this was the last suspension bridge built in the US?

Not until the Verrazano Narrows Bridge was opened in 1964, and it became taller than the Golden Gate Bridge. The most recent suspension bridge that opened last year is the Yangsigang Yangtze River Bridge which is located in Wuhan, China, the home of the first COVID-19 outbreak. The longest span of the bridge is 5,577 ft. and it’s the second longest suspension bridge in the world. It surpass the Verrazano Narrows Bridge and the Golden Gate Bridge.

This is an amazing video! However the Paseo Bridge was built in 1954 and the Delaware Memorial Bridge was not completed until 1951, thus this video cannot date to the 1940s as claimed in the description.

It looks like the copyright date on the video is MCMLX or 1960.

At 3:00, the narrator says that the “Suspension Bridge is called the Bridge of the Future”. Not until the Brooklyn Bridge first opened in 1883 was the first suspension bridge in New York. Followed by Williamsburg Bridge opened in 1903, and Manhattan Bridge opened in 1909. I don’t know what he was saying at 4:00 due to a bad film splice which was a jump cut.

I think he said 'spaced at intervals'.

@Musicradio77Network 4 жыл бұрын

ghost307 You’re right! That’s what the narrator said in a jump cut. The cable wires are spaced at intervals. Unlike all bridges in NYC, all cables on all bridges are spaced at intervals. The term “Bridge of the Future” was the modern suspension bridge. The Manhattan Bridge was the forerunner of the modern suspension bridge since it opened in 1909. Leon Moisseiff was the man who designed that bridge, along with the original Tacoma Narrows Bridge since it first opened in July 1940, and then collapsed in November of that same year due to heavy winds which cause the bridge to destroy them all, and it was the first suspension bridge disaster in the US.
