The Ken Lockwood Gorge Bridge is a steel plate girder bridge built for the High Bridge Branch of the Central Railroad of New Jersey (CNJ) to cross the South Branch Raritan River in Ken Lockwood Gorge of Hunterdon County, New Jersey.

[1] It is now open for pedestrian traffic on the Columbia Trail, a rail trail that starts in High Bridge.

On April 18, 1885, an iron ore train drawn by a Baldwin locomotive (#112), named Columbia, fell into the river when the center and southern spans collapsed.

Temporary repairs were then made to the bridge.

In 1931, it was strengthened to carry heavier loads.
