69th Street Transfer Bridge
Why it's listed
This railroad transfer bridge, also called a float bridge, stands on the Hudson River waterfront in Manhattan between West 66th and West 70th Streets. Completed in 1911 for the New York Central Railroad, it moved freight cars between land tracks and carfloats, the barges that carried rail cars around New York Harbor. Two steel plate girder spans, each carrying one track, hang from a shared overhead structure with counterweights and motor-driven threaded screws that raise and lower them. Its importance lies in engineering. Designed by James B. French and patented in 1911, it was the first bridge to use a contained apron, a flexible platform within the main span that absorbed the twisting of a listing carfloat. The design proved faster, easier to operate and cheaper than earlier suspended types, and later bridges in the port followed it. The bridge was taken out of service after the 1968 railroad merger but remains largely intact, minus its rails.
Significance in brief: The nomination argues it meets Criterion C in engineering as the first bridge of the "contained apron" design, patented by engineer James B. French. The design was faster, easier to operate and cheaper than earlier suspended transfer bridges, and later suspended bridges at the Port of New York followed it. It is described as one of the most significant marine structures remaining in New York City.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
Noted as vacant in the nomination. Nomination documents can be decades old; current status may differ. If you are considering buying an empty listed property, read the due-diligence checklist.
