At the time the design and the execution of the Niagara Falls Suspension Bridge was revolutionary, however, it’s original design was unable to keep up with the massive surge in transportation and the tremendous increase in the size of…
The bridge was a twin rib arch bridges and the arch was 1050 feet that reached from one side of the canyon to the other. These arches were Concrete-Steel Composite Arches and are the only kind of this in the United States. It is also the 2nd highest bridge in the United States.…
To do that Ceasar with his army had to cross Rhine river. The piers supporting the bridge were constructed of one and a half foot thick logs. These tigna bina were tied together in pairs with a two foot gap between them. They were then driven into the river bed at an oblique angle using a pile driver. This was apparently a large stone, attached to block and tackle on poles, that could be swung at the posts once they were tied into position. Once two sets of these posts were secure a large log ( was placed between them in the slot formed by the two foot gap. Angled supporting posts were tied to the tigna bina to provide additional support.Caesar says the piles were positioned forty feet apart before they were driven into the riverbed. Once the support structure was in place, logs were laid across the piers and then boards were used to form the roadway. Once the bridge was complete, the army crossed over the Rhine. They spent 18 days in the land of the Sugambri, burning abandoned villages because the enemy had fled their homeland in fear of the Roman juggernaut. After treating with the Ubii, Caesar crossed back over the Rhine and destroyed the bridge behind…
The purpose of this experiment is to study several bridges and build a bridge similar to the one that gave the students the uppermost muse. The students had to research facts about Truss Bridges, including its beginnings during the late 1700’s. Early Truss Bridge builders were first to spread its name throughout the United States, but the name of Truss Bridges soon cultivated across the world. There were numerous reasons as to why the design of Truss Bridges grew so broad. Firstly, the Revolutionary War destroyed the limited transportation the United States had left. The innovative and enhanced United States needed a more advanced form of transportation. For the reason that iron was not freely available, the idea of using…
The Romans used arches extensively. Arches did not require a lot of stone to construct yet were very sturdy. In fact, the ancient architecture is still able to meet modern needs. For example, the Aqua Virgo built by the Romans is still used for irrigation and…
Cable-stayed bridges look similar to suspension bridges, but support the weight load very differently. They are similar in the way that they both have towers, and the roadways are hung from cables, but are different in the way the cables are connected to the towers. In cable-stayed bridges, the cables are attached to the towers, which support the weight load. Unlike suspension bridges, in which the cables ride freely across the towers. For medium-length distances, 500 to 2,800 feet, cable-stayed bridges are quickly becoming bridges of choice because they require less cable, and the are quicker to…
The Brooklyn Bridge, originally known as the East River Bridge, is a bridge in New York City that spans over the East River. It is one of the oldest suspension bridges in the United States. This is the only bridge that connects the borough of Brooklyn to its sister, Manhattan. This bridge, with a huge span of 486.3m, was the longest suspension bridge in the world until 1903. Not only was it the longest, but it was the very first steel-wire suspension bridge in America.…
Assignment Discovery Online Curriculum Lesson title: Famous Bridges Grade level: 6-8, with adaptation for older students Subject area: Physical Science, Technology Duration: Two class periods Objectives: Students will: 1. Understand the benefits and drawbacks of different types of bridges. 2. Investigate the history and structural challenges of a prominent bridge. 3. Think about the challenges involved in building bridges. Materials: The class will need the following: • Computers with Internet access (optional but very helpful) • Reference materials on bridges Each group of three or four students will need the following: • Research material about a particular bridge (Web sites and books suggested below) • One long piece of butcher block paper • Pencils, colored markers, and crayons Each student will need the following: • One copy of the Classroom Activity Sheet: Bridge Research and • One copy of the Take-Home Sheet: Longest Suspension Bridges in the United States This lesson plan can be enhanced by purchasing a copy of the documentary Bridges: Design and Function at our School Store. The program airs on the Discovery Channel February 12, March 19, April 23, and May 28, 2001. Procedures: 1. Introduce the lesson by showing the class a picture of a popular bridge, such the Golden Gate Bridge (San Francisco) or the Brooklyn Bridge (New York City). Ask students to imagine what might happen if all the bridges in New York City or San Francisco were suddenly shut down. Then help the class brainstorm some ways that bridges affect our lives. For example, 1…
Romans created many things that we use today. One of them was aqueducts. They built them out of arches with channels over the top. Another was concrete. It was stronger than stone and used them to build bridges, arches, and…
A great example is the bridge built over the Tagus River in Spain. The arches measure 98 feet long weighing up to eight tons each. The bridge is still standing after nearly 2,000…
The Brooklyn Bridge is one of the most famous and iconic bridges in the United States along with The Golden Gate Bridge. The initial planning of this bridge took place in 1867 when New York State Senate approved a legislation about a New York Bridge Company and the largest suspension bridge project. The construction of the bridge started in 1869 by the designer and chief engineer John Roebling and officially opened for public on May 24, 1883. At that time, Brooklyn Bridge was considered the longest suspension bridge in the world and among the most celebrated architectures of the 19th century (Freeman, 2004).…
According to the U.S. Bureau of Transportation Statistics, there are approximately 600,000 bridges in the United States. The world's longest bridge is the Danyang–Kunshan Grand Bridge in China. The most expensive bridge is the Oakland Bay bridge in San Francisco. According to Guinness world records, the oldest bridge is the Bridge Over River Meles in Turkey. The Zhaozhou Bridge is the oldest standing bridge in China and the world’s oldest stone segmental arch bridge. The Brooklyn Bridge in New York was the longest suspension bridge when originally built. There are many more interesting facts about bridges but those are the main ones.…
The Romans were also the first to have sign posts indicating various destinations on their roads. The Romans were also the first to build large bridges over rivers. The main reason the Romans could build so many large structures, is because of their invention of the arch, a curved roof that distributes weight better than a straight roof. The Romans also were one of the first civilizations to heavily use marble in their architecture. They started their use of marble in 146 BCE.…
At the same time, cities were developing new techniques on road and bridge building. In 1880s, Brooklyn Bridge was completed made of steel cable suspension span designed by John A. Roebling. The new built bridge made it easier for pedestrians from the suburbs to access the city.…
They used the arch design in aqueducts and buildings like the Colosseum. The Pont du Gard, a famous aqueduct that carried water to the Roman city of Nimes, “was constructed entirely without the use of mortar” (Gwyther-Jones, 2). The design that the Romans used, the arch, required much less material to create. It placed the weight of the structure above it onto two separate placed, or the bases of the arch. This design was used so often by the Ancient Romans, because there were many uses for it, like using it as a bridge, tunnel, or a source of transportation for water. Arches were also appealing to the eye, and were used to tell stories. The triumphal arch, a type of arch that was specifically used “to commemorate military triumphs and other significant events such as the accession of a new emperor” (Cartwright, 1), but “had no practical function” (Cartwright, 1). Surprisingly, the Ancient Romans did not create the arch, they adapted to the design, that was created by the Etruscans. Instead, they improved upon, and modified the Etruscan…
