Maumee Sidecut

Why it's listed
Built in the late 1830s, the Maumee Sidecut was a 1.7-mile canal section that let boats move between the Miami-Erie Canal and the Maumee River. Six locks of cut stone shipped from Marblehead raised or lowered vessels about 50 feet. Surveying began in 1824, but funding disputes, the Ohio-Michigan boundary conflict, rivalry among Toledo, Perrysburg and Maumee over the canal's end, and a financial panic delayed completion until 1842. Traffic began in May 1843. After the full canal opened in 1845, the sidecut was used heavily, and 375 boats passed through in 1848. Extension of the main line into Toledo bypassed it, and the state abandoned it in 1850. It was listed as an outstanding engineering achievement of Ohio's early canal era. Today it forms part of a park. The masonry of locks two, three, four and six remains, lock five carries a bridge, and lock one was removed for a highway.
Significance in brief: The sidecut was part of the Miami-Erie Canal system and sat where traffic bound for the Maumee River left the main line. The nomination calls it one of the outstanding engineering achievements of the early Ohio canal system and stresses its importance to the settlement and growth of northern Ohio. It operated only briefly before the state abandoned it in 1850.
