. The Bridge of the Americas greatly increases road traffic capacity across the Canal. Two earlier bridges cross the Canal, but they use moveable designs and have limited traffic capacity. These earlier spans include a small swinging road bridge, built into the lock structure at Gatún, and a swinging road/rail bridge constructed in 1942 at Miraflores. The Centennial Bridge was constructed to eliminate the bottleneck of, and reduce traffic congestion on, the Bridge of the Americas. The bridge is a

History


The need for a bridge

From the beginning of the French project to construct a canal, it was recognised that the cities of Colón and
Panamá Panama ( , ; es, link=no, Panamá ), officially the Republic of Panama ( es, República de Panamá), is a transcontinental country spanning the southern part of North America and the northern part of South America. It is bordered by Cost ...
would be split from the rest of the republic by the new canal. This was an issue even during construction, when barges were used to ferry construction workers across the canal. After the canal opened, the increasing number of cars, and the construction of a new road leading to Chiriquí, in the west of Panama, increased the need for some kind of crossing. The Panama Canal Mechanical Division addressed this in August 1931, with the commissioning of two new ferries, the ''Presidente Amador'' and ''President Washington''. This service was expanded in August 1940, with additional barges mainly serving the military. On June 3, 1942, a road/rail swing bridge was inaugurated at the Miraflores locks; although only usable when no ships were passing, this provided some relief for traffic wishing to cross the canal. Still, it was clear that a more substantial solution would be required. To meet the growing needs of vehicle traffic, another ferry, the ''Presidente Porras'', was added in November 1942.


The Bridge Project

The idea of a permanent bridge over the canal had been proposed as a major priority as early as 1923. Subsequent administrations of Panama pressed this issue with the United States, which controlled the Canal Zone; and in 1955 the Remón-Eisenhower treaty committed the United States to building a bridge. A contract worth $20,000,000 was awarded to John F. Beasly & Company who built the bridge out of steel and reinforced concrete, and the project was initiated in a ceremony which took place on December 23, 1958, in the presence of United States Ambassador Julian Harrington, and Panamanian President
Ernesto de la Guardia Navarro Ernesto de la Guardia Navarro (May 30, 1904 in Panama City, Panama – May 2, 1983 in Panama City) was president of Panama from October 1, 1956 to October 1, 1960. He belonged to the National Patriotic Coalition (CNP). Early life and educati ...
. Construction began on October 12, 1959, and took nearly two and a half years to complete. The inauguration of the bridge took place on October 12, 1962, with great ceremony. The ribbon was cut by

, after which those present were allowed to walk across the bridge. The ceremony was given full nationwide coverage on radio and television; significant precautions were taken to manage the large crowds of people present. These proved inadequate, however, and pro-Panamanian protesters disrupted the ceremony, even removing the memorial plaques on the bridge.


Post-construction

When opened, the bridge was an important part of the
Pan-American Highway The Pan-American Highway (french: (Auto)route panaméricaine/transaméricaine; pt, Rodovia/Auto-estrada Pan-americana; es, Autopista/Carretera/Ruta Panamericana) is a network of roads stretching across the Americas and measuring about in to ...
, and carried around 9,500 vehicles per day; however, this expanded over time, and by 2004 the bridge was carrying 35,000 vehicles per day. The bridge therefore became a significant bottleneck on the highway, which led to the construction of the Centennial Bridge, which now carries the Pan-American Highway too. On May 18, 2010, the bulk cargo ship ''Atlantic Hero'' struck one of the protective bases of the bridge after losing engine power, partially blocking that section of the canal to shipping traffic. The bridge did not receive damage and there were no fatalities. In December 2010, the Centennial Bridge access road collapsed in a mudslide, and commercial traffic was diverted to the Bridge of The Americas.


The "Thatcher Ferry Bridge"

Commemorative Issue of 1962 The bridge was originally named "Thatcher Ferry Bridge", after the original ferry which crossed the canal at about the same point. The ferry was, in turn, named after Maurice H. Thatcher, a former member of the Canal Commission, who introduced the legislation which created the ferry. Thatcher cut the tape at the inauguration of the bridge. The name was unpopular with the government of Panama, however, which preferred the name "Bridge of the Americas". The Panamanian view was made official by a resolution of the
National Assembly In politics, a national assembly is either a unicameral legislature, the lower house of a bicameral legislature, or both houses of a bicameral legislature together. In the English language it generally means "an assembly composed of the repr ...
on October 2, 1962, ten days before the inauguration. The resolution read as follows:
The bridge over the Panama Canal shall bear the name Bridge of the Americas. Said name will be used exclusively to identify said bridge. Panamanian government officials shall reject any document in which reference is made to the bridge by any name other than "Bridge of the Americas". A copy of this resolution, with the appropriate note on style, shall be forwarded to all legislative bodies of the world, so that all may give the bridge the name chosen by this honorable assembly, complying with the express will of the Panamanian people. Given in the city of Panama on the second day of the month of October of nineteen hundred and sixty-two. :President, Jorge Rubén Rosas :Secretary, Alberto Arango N.

said in his speech: "we can look today to this bridge as a new and bright step toward the realization of that dream of a Pan-American Highway, which is now almost a reality. The grand bridge we inaugurate today — truly a bridge of the Americas — completes the last stage of the highway from the United States to Panama". Nonetheless, the official name of the bridge became the "Thatcher Ferry Bridge" and remained so until Panamanian control in 1979.
