Canal construction resumed in April 1824, and within several years some 2,600 men were digging and hauling dirt from the ditch. Laborers toiled with pick and shovel at the immense construction task, working for an average daily wage of 75 cents. The swampy marshlands along the canal's planned route proved a great impediment to progress; workers continuously battled slides along the "ditch's" soft slopes. It was 1829 before the C&D Canal Company could, at last, announce the waterway "open for business". Its construction cost of $3.5 million made it one of the most expensive canal projects of its time.
