Lynn Canal runs about 90 miles (140 km) from the inlets of the Chilkat River south to Chatham Strait and Stephens Passage. At over 2,000 feet (610 m) in depth, Lynn Canal is the deepest fjord in North America (outside Greenland) and one of the deepest and longest in the world.
Based on the design of the Berendrecht Lock, it has the same length and width, but with an operational depth (TAW) of 17.8 metres (58 ft), which makes it the world's largest lock. To construct the lock, 9.1 million m 3 of earth was excavated, and 22,000 tonnes of structural steel, three times the amount required to build the Eiffel Tower .
