The Great Bridge: A Marvel of Engineering


In the middle of the 19th century, the cities of New York and Brooklyn were two separate places divided by the wide, churning East River. For years, the only way to travel between them was by ferry boat. This was often slow and dangerous, especially when the river froze over in the winter. People dreamed of a way to connect the two cities permanently. That dream began to take shape through the vision of a brilliant civil engineer named John Augustus Roebling. He proposed a massive suspension bridge, a design that was much larger and stronger than anything built before.
- Suspension bridge:
- A type of bridge in which the deck is hung below suspension cables on vertical suspenders.
- Caisson:

- Civil engineer:
