The crossing occurred during a 6,mile sea voyage from Jacksonville, Florida, to Los Angeles in Even though world shipping—and the size of ships themselves—has changed markedly since the canal was designed, it continues to be a vital link in world trade, carrying more cargo than ever before, with fewer overhead costs.

Opponents to the Torrijos-Carter Treaties feared that efficiency and maintenance would suffer following the US withdrawal from the Panama Canal Zone; however, this has been proven not to be the case.

Capitalizing on practices developed during the American administration, canal operations are improving under Panamanian control. The accident rate has also not changed appreciably in the past decade, varying between 10 and 30 accidents each year from about 14, total annual transits.

Increasing volumes of imports from Asia , which previously landed on US West Coast ports, are now passing through the canal to the American East Coast.

The canal's fiscal year runs from October through September. This is supported by new equipment, such as a new drill barge and suction dredger, and an increase of the tug boat fleet by 20 percent. Improvements have been made to the traffic management system to allow more efficient control over ships in the canal. In December , record-breaking rains caused a hour closure of the canal; this was the first closure since the United States invasion of Panama in The canal is currently handling more vessel traffic than had ever been envisioned by its builders.

In it was estimated that the maximum capacity of the canal would be around 80 million tons per year; [95] as noted above, canal traffic in reached To improve capacity, a number of improvements have been made to the current canal system.

These improvements aim to maximize the possible use of current locking system: It should be noted that these improvements were started before the new locks project, and are complementary to it. Despite having enjoyed a privileged position for many years, the canal is increasingly facing competition from other quarters.

Because canal tolls have risen as ships have become larger, some critics [97] have suggested that the Suez Canal is now a viable alternative for cargo en route from Asia to the US East Coast. The increasing rate of melting of ice in the Arctic Ocean has led to speculation that the Northwest Passage or Arctic Bridge may become viable for commercial shipping at some point in the future.

However, such a route is beset by unresolved territorial issues and would still hold significant problems owing to ice. Gatun Lake is filled with rainwater, and the lake accumulates excess water during wet months.

Since a ship will have to go upward to Gatun Lake first and then descend, a single passing will cost double the amount; but the same waterflow cycle can be used for another ship passing in the opposite direction. The ship's submerged volume is not relevant to this amount of water.

As a signatory to the United Nations Global Compact and member of the World Business Council for Sustainable Development, the ACP has developed an environmentally and socially sustainable program for expansion, which protects the aquatic and terrestrial resources of the canal watershed.

The expansion guarantees the availability and quality of water resources by using water-saving basins at each new lock. These water-saving basins diminish water loss and preserve freshwater resources along the waterway by reusing water from the basins into the locks. Each lock chamber has three water-saving basins, which reuse 60 percent of the water in each transit.

There are a total of nine basins for each of the two lock complexes, and a total of 18 basins for the entire project. As demand is rising for efficient global shipping of goods, the canal is positioned to be a significant feature of world shipping for the foreseeable future.

However, changes in shipping patterns —particularly the increasing numbers of larger-than-Panamax ships— necessitated changes to the canal for it to retain a significant market share. In it was anticipated that by , 37 percent of the world's container ships would be too large for the present canal, and hence a failure to expand would result in a significant loss of market share.

Close to 50 percent of transiting vessels were already using the full width of the locks. The proposal to expand the canal was approved in a national referendum by about 80 percent on October 22, The expansion plan had two new flights of locks built parallel to, and operated in addition to, the old locks: Each flight ascends from sea level directly to the level of Gatun Lake; the existing two-stage ascent at Miraflores and Pedro Miguel locks was not replicated.

The new locks are supported by new approach channels, including a 6. The maximum level of Gatun Lake was raised from These gravity-fed basins allow 60 percent of the water used in each transit to be reused; the new locks consequently use 7 percent less water per transit than each of the existing lock lanes.

The deepening of Gatun Lake and the raising of its maximum water level also provide capacity for significantly more water storage. These measures are intended to allow the expanded canal to operate without constructing new reservoirs.

Tolls will continue to be calculated based on vessel tonnage, and in some cases depend on the locks used. An article in the February issue of Popular Mechanics magazine described the plans for the canal expansion, focusing on the engineering aspects of the expansion project.

The first phase of the project was the dry excavations of the meters feet wide trench connecting the Gaillard Cut with the Pacific coast , removing 47 million cubic meters of earth and rock. The design of the locks is a carbon copy of the Berendrecht Lock , which is 68 m wide and m long, making it the largest lock in the world. Completed in by the Port of Antwerp , which De Nul helped build, the company still has engineers and specialists who were part of that project.

In January , a contract dispute threatened the progress of the project. In June , flooding of the new locks began: The new locks opened for commercial traffic on 26 June , and the first ship to cross the canal using the third set of locks was a modern New Panamax vessel, the Chinese-owned container ship Cosco Shipping Panama. The construction work was projected by HKND to begin in and take 5 years.

The government of Nicaragua hopes this will boost the economy; the opposition is concerned with its environmental impact. According to the independent impact assessment by British firm ERM [] , some 30, local residents will be displaced by the canal, although opposition leaders and Amnesty International claim the figure will be in the hundreds of thousands.

Supporters and the environmental impact study claim there will be net environmental benefits, but critics argue that nearly a million acres of delicate ecosystems will be destroyed by the time construction is completed. However, plans to construct these sea-rail-sea links have yet to materialize. This service can be requested from the Panama canal authority at any time who will consider each request.
