Marble Hill

How did part of Manhattan become joined to the Bronx by moving a river?

During our walking tours of Marble Hill, engineer Bryan Diffley, Project Manager of the High Bridge restoration, for a walk exploring how the Harlem River was re-engineered and bridged over.
The construction of the Harlem Ship Canal created a naval passage to the Hudson River. Its 1895 opening was celebrated with extravagant festivities. The Canal severed Marble Hill from Manhattan, forever changing the river’s ecology.​

Getting from Manhattan to the Bronx was never easy. We'll also explore the history of the bridges that once crossed the Harlem River, the King’s Bridge and Dykeman’s Bridge.
