Miami and Erie Canal Deep Cut

The Miami and Erie Canal Deep Cut is a historic canal section near Spencerville that runs through solid limestone and clay for about 6,600 feet. In some places, the excavation reaches depths of around 52 feet (16 meters), since it connects two separate watersheds.

Between 1825 and 1845, local workers, convicts, and Irish immigrants excavated this canal section using simple hand tools. The project was part of a larger effort to improve economic connections across Ohio through water transport.

This canal section stands as a testament to the ambition of 19th-century builders who wanted to connect distant regions through water routes. Visitors today can see how much effort went into creating this passage and appreciate what it meant for trade and travel in that era.

The park at 22900 South Saint Marys Road offers hiking trails and picnic areas for exploring the historic canal. A covered shelter with climate control provides weather protection and serves as a good starting point for visitors.

Instead of building locks, engineers decided to dig straight through a ridge, creating the deepest hand-dug canal section in the United States. This bold decision saved time and money but made the work extremely hazardous for laborers.
