The Importance of Bridges to Society

Society has always relied on transportation to survive. When man first walked the earth he relied on himself for transportation. Eventually man learned to tame wild animals and use them as a form of transportation. And finally he created machines to take him places he could not reach on his own or with the assistance of any animal. Along with the evolution of transportation came maps to mark the locations of routes taken between cities and important locations. One invention developed to expand the reach of travelers was the bridge.

The earliest bridges were based on anything seen in nature such as fallen trees and eroded earth or rocks. They were developed to provide a safe crossing for people, originally on foot but later on horse back and then mechanized transportation, to travel from one prominent city of industrial strength to another. Although for many centuries boats were still the main form of transportation over distances of water. In Henry Petroski's book, Engineers of Dreams, he discusses significance of bridges and bridge engineering in history by connecting then back to the Stone Age and analyzing the impact they have had on society. Petroski analyzes the issues, insensitivity and wonder people in society have with the structures. He focuses mainly on the bridges built in the United States during the bridge building era from eighteen-seventies through the nineteen-thirties because they were the years of the industrial r...

  • Bailey Island Bridge Case Study

    1737 Words  | 4 Pages

    The Bailey Island Bridge is located in Harpswell, Maine on Route 24. Before the making of the bridge, the fishermen that lived on Bailey’s Island wanted a bridge that connected their island to Orr’s Island. The town of Harpsweell made and voted on their decisions in the weekly town meetings (“Bailey”). The project was stalled because of some of the mainlanders in the town, but it was brought back up for discussion in 1912. They first agreed on a “road” which would connect the two islands and would be constructed with timber. This was to cost $3,000. The cost quickly reached $25,000 at a later town meting because they decided to build the bridge with stone and concrete instead. Once the legislature decided to pass a bill stating that it would fun state’s highway and bridge projects, they decided to move forward with the project (Hansen, 36).

  • Essay On The Ambassador Bridge

    904 Words  | 2 Pages

    At the time of its construction in 1929, the Ambassador Bridge was the largest spanned suspension bridge at 564 meters until the George Washington Bridge was built. It was an engineering masterpiece at the time. The total bridge length is 2,286 meters and rises to 118 meters above the river. Suspension cables support the main span of the Ambassador Bridge and the main pillars under the bridge are supported by steel in a cantilever truss structure. In total, the McClintic-Marshall masterpiece is comprised of 21,000 tons of steel.

    The Golden Gate bridge, standing as an icon of roadway innovations, took multiple engineers years to design and complete. They could not just simply build an ordinary bridge. They had to take into consideration the physics behind it, as well as, what kind of effect the environment would have upon the bridge. The bridge sits along one of the most active fault lines in the world, so engineers had to make sure their bridge could withstand a little movement. Today the Golden Gate bridge still stands tried and true, as does many other innovations that 20th century engineers came up with.

    The first and most challenging problem associated with building the Mackinac Bridge arrived long before the bridge was even designed. Financing such an enormous project was no easy feat. In 1928, the idea of connecting the upper and lower peninsulas was proposed to Congress for the first time (Brown 4). At the time, the suspected bridge project was very much under government scrutiny and control. In fact, the initial boost in interest in pursuing the construction of a bridge came about due to the depression. The Public Works Administration (PWA) had been created under President Franklin D. Roosevelt’s New Deal economic plan which would fund certain construction projects with th...

  • Benefits of the Market Revolution on the Economy

    616 Words  | 2 Pages

    Transportation improved from the market revolution through many new inventions, railroads, steamboats, and canals. Pressure for improvements in transportation came at least as much from cities eager to buy as from farmers seeking to sell. The first railroad built was in 1792, it started a spread throughout the states. Cumberland which began to be built in 1811 and finished in 1852, known to be called the national road stretched over five hundred miles from Cumberland to Illinois. By 1821, there were four thousand miles of turnpike in the United States. Turnpikes were not economical to ship bulky goods by land across long distance across America, so another invention came about. Robert Fulton created steam boats in 1807; he named his first one ‘Clermont.’ These steam boats allowed quick travel upriver against the currents, they were also faster and cheaper. The steamboats became a huge innovation with the time travel of five miles per hour. It also stimulated agricultural economy of west by providing better access to markets at lower cost. While steamboats were conquering the western rivers, canals were being constructed in the northeastern states. The firs...

  • Urban Transportation Essay

    2103 Words  | 5 Pages

    The development of urban transportation has not changed with the cities; cities have changed with transportation. This chapter offers an insight into the Past and the future of Urban transportation and is split up into a number of different sections.  It includes a timeline of the different forms of transport innovations, starting from the earliest stages of urban transport, dating back to the omnibus (the first type of urban transportation) and working in a chronological order until eventually reaching the automobile. However, these changes in Urban transport did not happen for no reason. Different factors within society meant urban transport needed to evolve; points will be made on why society needed this evolution. In contrast I will observe the problems urban transport has caused in society as a result of its rapid progression. Taking account of both arguments for the evolution of urban transport, I will look at where it will go in the future.
