Completed in 1825, the Erie Canal was rebuilt or enlarged twice as transportation changed. The original canal, known as Clinton's Ditch, was only 40 feet wide and four feet deep, and its success quickly showed that it had been built too small. Between 1836 and 1862, the Enlarged Erie Canal increased the canal's depth to seven feet and its width to seventy feet, but even those dimensions proved inadequate against transportation advances of the early 20th century. Lock 13 of the modern Erie Canal was constructed as part of the canal's third iteration, the Barge Canal, built between 1905 and 1918. The modern canal system uses New York's inland lakes and rivers as part of the navigation channel and was designed to accommodate barges carrying 3000 tons of cargo, 100 times more than a canal boat from the 1820s. Long before railroads, interstate highways, or jets, the 363-mile-long waterway established the first all-water navigation route between the Atlantic Ocean and the upper Great Lakes, opened the continent's interior to settlement and commerce, and helped make New York City an international center of trade. After a century of continuous operation, more than 500 miles of navigable waterway, 300 miles of recreational trails, and 324 communities across upstate New York remain part of this canal system.
