The Smith-Ransome Japanese Bridge of South Ferry Hills on Shelter Island, New York is one of the first 'reinforced concrete construction' structures built in North America by engineer Ernest L. Ransome for the mineral prospector known as the "Borax King", Francis Marion Smith.

[3] In 1886 Ransome built the two small underpass bridges in the Golden Gate Park, San Francisco, one of which survives today.

[5]: p.33  In 1897 he completed the Pacific Coast Borax Refinery in Bayonne, New Jersey and Smith had him work on the 60 foot x 6 feet wide bridge at Presdeleau.

One hundred years later the estate at Presdeleau had been apportioned and sold in smaller parcels, leaving the Japanese bridge in need of restoration.

The small bridge is just behind the beach at Smith Cove on the Peconic River and it looks out at the upper Sag Harbor bay from South Ferry hills.
