Lighthouses of Panamá

For many Panamanians, ‘lighthouse’ means the cancelled project to build one of the tallest buildings in Latin America in Panama City. ‘The Faros del Panamá’ (Panama Lighthouse) was a skyscraper complex designed by Chapman Taylor, With a central tower of 84 floors and a planned height of 346 metres, it would probably have been the tallest building in Latin America, had it not been dogged by financial difficulties and been cancelled.

However, for those who sail Panama’s waters or pass through the canal, lighthouses mean the real thing, beacons to keep their vessels from running aground. Not surprisingly, most Panamanian lighthouses are associated with the canal.

The canal is split into 5 sections for the purposes of classifying the lighthouses along the banks, The first section covers the deep water at the Atlantic end of the canal through to Gatun and is termed the ‘Atlantic Section’. The second group of lighthouses, known as the ‘Gatun Section’ cover the section between Gatun and Gamboa. The third group of lighthouses covers the section between Gamboa and the Pedro Miguel Locks and is called the ‘Culebra Cut Section’. Te fourth section, designated as the ‘Miraflores Lake Section’ covers the stretch of canal between the Pedro Miguel Locks and the Miraflores Locks. The final section, from the Miraflores Locks to deep water at the Pacific end of the canal is known as the ‘Pacific Section’.

No definitive list of he canal lighthouses has ever been produced, but 35 were originally constructed to help guide ships using the Canal. Most of these are believed to be still in use. One that is no longer in use was at the Gatun locks and was probably the only lighthouse ever built above a railway line. Many are nothing more than simple automated lights, but there are also numerous ‘traditional-style’ tower lighthouses, which whilst they may no longer be permanently staffed, once were. These can be most easily seen at the canal entrances and locks.

As well as the lighthouses within the canal, or sited to guide ships to and from it, there are other lighthouses around Panama’s coastlines, though many are located on remote islands where they can only be seen by boat. Although none are particularly large or famous, the variety of structures and their unsung contribution to the safety of world trade makes them interesting in their own right.

The Centennial Bridge

For more than 30 years, the only fixed crossing of the Panama Canal was the Bridge of the Americas, and although this allowed two-lanes of traffic in each direction, it was not designed to cope with the levels of traffic that were using it by the end of the twentieth century. Originally, it carried around 9,500 vehicles per day, but by the time that the Centennial Bridge opened it was carrying more than 35,000 vehicles every day.

Since the Bridge of the Americas represented a major bottleneck in the Pan-American Highway, the Panamanian government decided that a second fixed crossing was needed, and in 2000, Panama’s Ministry of peoples Works invited tenders for a second canal crossing. The contract to construct the bridge was awarded in March 2002m and a very ambitious construction schedule was set in order that the bridge could be inaugurated on the 90th anniversary of the first ship transit of the Panama Canal by the cargo ship Ancon, on 15 August 1914.

The bridge was named for Panama’s centennial (100 year anniversary of the establishment of the independent nation), which occurred on 3 November 2003. The bridge was designed as a joint venture between T.Y. Lin International and the Louis Berger Group Inc, and constructed by German based Bilfinger Berger utilizing resources from its Australian subsidiary Baulderstone Hornibrook. Boston-based transportation architect Miguel Rosales from Rosales + Partners created the concept and initial aesthetic designs for the Panama-Centennial Bridge. Structural engineering contracts were awarded to Leonhardt, Andrä and Partner.

The bridge was inaugurated on schedule on 15 August 2004, although it was opened for traffic on 2 September 2005, when the new highways leading to it were finished. The bridge is designed to withstand the earthquakes which are frequently recorded in the canal area, and was built with the west tower approximately 50 meters inland to allow for the planned canal widening. The bridge is a cable stayed design with a total length of 1,052m and a central span of 420m. With 80 meters of clearance above the waters of the can, it is significantly higher than the Bridge of the Americas.

The Centennial Bridge is 15km north (inland) of the Bridge of the Americas, and crosses the famous Gaillard Cut section of the Panama Canal close to the Pedro Miguel locks. New road links connecting Arraijan in the west to Cerro Patacon in the east via the bridge, enabled the new bridge to provide the alleviation of traffic on the Bridge of Americas for which it was designed. The rapid construction schedule did prove to have some consequences, and in December 2010, the sub-standard construction of one of the access roads was demonstrated when heavy rains and flooding caused it to collapse.
