TAPPAN ZEE BRIDGE
The Governor Mario M. Cuomo Bridge is defined by a cable‑stayed design with 419‑foot towers and a harp‑like array of steel cables spanning the Hudson River. A fully programmable LED lighting system designed by DGA illuminates the towers, cables, piers, and shared‑use paths, emphasizing the bridge’s structural geometry while enhancing nighttime visibility. Connected LED technology by Philips/Signify enables dynamic lighting displays, remote control, and energy‑efficient operation for civic events and everyday use.

HISTORY REVITALIZED
The Tappan Zee Bridge features a fully programmable LED lighting system that transforms the span into a vivid nighttime landmark. Dynamic, color‑changing illumination highlights the cables, towers, and structural surfaces, extending across the length of the roadway and public pathways. A cloud‑connected control system enables remote programming, real‑time monitoring, and energy‑efficient operation, while precision‑focused LEDs enhance visibility and minimize light spill into the surrounding environment. Together, these elements create one of the most technologically advanced illuminated bridges in North America.
HISTORY REMEMBERED
The original Tappan Zee Bridge opened on December 15, 1955, spanning one of the widest points of the Hudson River and linking South Nyack and Tarrytown. Built between 1952 and 1955, it became a vital part of the New York State Thruway, carrying Interstate 87 and 287 and serving as a major commuter and commercial route for the region. At more than three miles long, it was the longest bridge in New York and an important engineering achievement of its era.
