The steel truss arch bridge spans over the Pacific entrance of the Panama canal. The bridge was designed and constructed by John F. Beasly & Company in 1962 and was the only permament link between the two continents until the opening of the Centennial Bridge in 2004. The bridges main span is 344 meters long and the deck is 61 meters over the water level from its highest point. The 10 meter wide deck carries four road lanes and two pedestrian lanes, one on each side. When opened in the early sixties, the Pan-American Highway crossing the brige had an average traffic of about 9,500 vehicles per day. By 2004 the traffic has increased to 35,000 vehicles per day. This led eventually to the construction of the Centennial Bridge.
