This is a 25 slide, highly animated, power point presentations on a National Construction Project - Building the Brooklyn Bridge. Each of the presentation slides are editable so you can change it to fit your individual needs.
Of all the engineering advances in the 1800s, the Brooklyn Bridge stands out as perhaps the most famous and most remarkable. It took more than 14 years to build, involved 600 workers and cost $15 million (more than $320 million in today’s dollars). At least 24 people died in the process, including its original designer. It was constantly criticized by skeptics who predicted the entire structure was going to collapse into NY's East River.
The idea of connecting 2 growing cities of New York and Brooklyn was thought to be impossible because of the width of the waterway, which, despite its name, wasn’t really a river. The East River is actually a salt water estuary, prone to turbulence and tidal conditions. Further complicating matters was the fact that the East River was one of the busiest waterways on earth, with hundreds of crafts of all sizes sailing on it at any time. Any bridge spanning the water would have to allow for ships to pass beneath it, meaning a very high suspension bridge was the only practical solution.
On May 24, 1883, the Brooklyn Bridge over the East River opened, connecting the great cities of New York and Brooklyn for the first time in history. Thousands of residents of Brooklyn and Manhattan Island turned out to witness the dedication ceremony, which was presided over by President Chester A. Arthur and New York Governor Grover Cleveland.
A number of speakers lauded the bridge, calling it a "Wonder of Science" and lauding its anticipated contribution to commerce. The bridge became an instant symbol of the age. More than 125 years after its completion, this iconic feature of the New York City skyline still carries roughly 150,000 vehicles and pedestrians every day.
The presentation covers the following:
