The Construction of this canal was begun on the 15th of April, 1824, by Silas E. Weir, the chairman of the first committee of work whose zealous and efficient services to the company terminated with his life on the 14th day of May 1828. He was succeeded by Robert M. Lewis under whose active supervision, the work was continued and finished.In its progress through the Eastern level, large sections of embankment sunk 100 feet below the adjoining surface and the bottom of the excavation rose 10 feet above its natural position. On the Deep Cut more than 375,000 cubic yards of earth slipped from the regulated slopes of the sides and passed into the chamber of the canal.
These and many other difficulties having been overcome, the water was introduced on the 4th of July 1829 and the final accomplishment of this great National work was celebrated on the 17th of October of the same year at which time the navigation was opened.
