History

A bridge at this location was proposed as early as 1906, but Spuyten Duyvil residents and other civic groups opposed the bridge, arguing that it would destroy the virgin forest of Inwood Hill Park and bring traffic congestion to Bronx communities.

preferred the route along the Hudson River because he was able to receive the land to build the Henry Hudson Parkway at no cost and use federal labor to build the parkway. The construction of the bridge helped open the Riverdale neighborhood to development. The original single-deck structure was built for the Henry Hudson Parkway Authority by the American Bridge Company at a cost of $4.949 million and opened on December 12, 1936. The upper level of the bridge was designed to be added at a later date and opened to traffic on May 7, 1938. The second deck was added at an additional cost of about $2 million, after toll revenues allowed its construction. A rehabilitation project commenced in 2000 and was carried out by Steinman, Boynton, Gronquist and Birdsall, a successor of David B. Steinman's firm. Repairs took place nearly continuously for at least a decade, at a cost of $160 million. The bridge was renovated from late 2017 to late 2020. The $86 million project replaced the last remnants of the original upper and lower decks, reopened the pedestrian and cycling path, eliminated the lower-level toll booth, upgraded roadway lighting, and made seismic improvements.

Tolls

As of April 11, 2021, drivers pay $7.50 per car or $4.28 per motorcycle for tolls by mail/non-NYCSC E-Z Pass. E ZPass users with transponders issued by the New York E ZPass Customer Service Center pay $3.00 per car or $2.05 per motorcycle. Mid-Tier NYCSC E-Z Pass users pay $4.62 per car or $3.17 per motorcycle. The original toll was 10 cents. In January 2010, the MTA announced that it planned to implement a

The new tolling system was implemented on November 10, 2012, and has since been implemented on all nine MTA crossings. On November 20, 2016, the tollbooths were dismantled, as drivers were no longer able to pay cash at the bridge. Instead, cameras and
