Afro-Panamanian
In 1904 when the construction of the Panama Canal was taken over by the United States for the failure of the French company, will again resort to the West Indian worker. Although between 1904 and 1914 the vast majority of Afro-West Indians who arrived in Panama did a one-year contract with the idea of returning to their home islands once the offshore project, after construction of the canal many Afro-Antillean stayed in Panama. Afro-West Indians who remained in Panama many got jobs in the Canal Zone and became the largest immigrant group in Panama. On the subject of Afro-Antillean Panama, Leslie B. Rout said that when the canal was opened in 1914, some 20,000 African-West Indians remained in Panama.
Bridge of the Americas
The Bridge of the Americas crosses the Pacific approach to the Panama Canal at Balboa, near Panama City. It was built between 1959 and 1962 by the United States at a cost of US$20 million. From its completion in 1962 until the opening of the parallel Centennial Bridge in 2004, the Bridge of the Americas was a key part of the Pan-American Highway. 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.
