Panama Canal
France began work on the canal in 1881, but stopped due to engineering problems and a high worker mortality rate. The United States took over the project in 1904 and opened the canal on August 15, 1914. One of the largest and most difficult engineering projects ever undertaken, the Panama Canal shortcut greatly reduced the time for ships to travel between the Atlantic and Pacific Oceans, enabling them to avoid the lengthy, hazardous Cape Horn route around the southernmost tip of South America via the Drake Passage or Strait of Magellan.
Bayonne Bridge
The Port Authority believed that it was possible to build the new roadway without interrupting traffic flow between Staten Island and Bayonne. In July 2012, the Port Authority announced construction would begin in the summer of 2013, to be completed by 2017. In this timeline, removal of the existing roadway would be completed by late 2015, in time for the opening of the widened Panama Canal. The project would cost $1.7 billion and last five years.
