Newburgh Lock and Dam, Lock and gravity dam on Ohio River, Henderson County, United States

Newburgh Lock and Dam is a water control structure spanning the Ohio River with two separate locks that allow vessels to pass through different water levels. The facility uses large gates to regulate flow and maintain a stable water level for navigation year-round.

Newburgh Lock and Dam replaced Ohio River locks and dams 46 and 47, consolidating two older structures into a single site. It is the 16th lock and dam on the river, standing 776 miles (1,249 km) downstream of Pittsburgh. The sources give no construction dates for the replacement.

The facility connects communities along the Ohio River through water transportation, supporting local commerce and regional trade. This connection shapes how people in the area interact and depend on the river for their livelihoods.

The location is best visited during daylight hours when river activity is visible and the structure can be seen clearly. Public access is available from nearby roads and walking paths, though visitors should stay aware of active shipping traffic.
