the Panama maritime route. As approved by the Panamanian people, construction for the expansion project was slated to conclude by April 2016. The ACP said it would use all possible means to stretch capacity until the construction is completed. The proposed expansion of the canal by the construction of a third set of locks will allow it to capture the entire demand projected through 2025 and beyond. Together, the existing and new locks will approximately double the capacity of the present canal. Critics such as former legislator Keith Holder, co-author of the legislation that created the ACP, pointed out that canal usage is seasonal and that even during the few months when it is most crowded, the bottleneck that slows traffic is not the locks but the narrow Culebra Cut, which has a limited capacity for large ships to pass one another. Although the canal was nearing its maximum capacity, it did not mean that ships were unable to transit it. Rather, the canal's growth capacity stagnated and that it could not capture additional cargo volumes. The former head of the Panama Canal's dredging division, Thomas Drohan, a critic of the expansion plan, discounted allegations that this is a problem in the short term. He argued that if the supply of any good or service becomes short, businesses can raise their prices; this would apply to Panama Canal tolls as much as it does to petroleum. The project Locks The original canal has two lanes, each with its own set of locks. The expansion project added a third lane through the construction of lock complexes at each end of the canal. One lock complex is located on the Pacific side, southwest of the existing Miraflores Locks. The other is located east of the existing Gatun Locks. Each of these new lock complexes have three consecutive chambers designed to move vessels from sea level to the level of Gatun Lake and back down again. Each chamber has three lateral water-saving basins, for a total of nine basins per lock and 18 basins in total. Just like the original locks, the new locks and their basins will be filled and emptied by gravity, without the use of pumps. The location of the new locks uses a significant portion of the area excavated by the United States in 1939 and suspended in 1942 because of World War II. The new locks are connected
