1995 - Before the closure and demolition of GM's North Tarrytown Assembly

2020 - North Tarrytown Assembly Demolished, environmental remediation underway, to be re-developed

The North Tarrytown Assembly  plant, located in what is now Sleepy Hollow, New York, was one of General Motors' most historic and longest-running facilities,operating for nearly a century from 1900 to 1996. 

 

Early History & Maxwell-Briscoe (1900–1914)

 

• The Walker Steamer: The facility opened in 1900 on the shores of the Hudson River to produce the "Mobile" steam carriage for the Mobile Company of America.
• Transition to Gas: By 1903, steam power had lost its appeal, and the plant was leased to Maxwell-Briscoe. For a time, it was one of the largest and most advanced automobile factories in the world, designed by the famous architectural firm McKim, Mead & White. 

 

The Chevrolet and GM Era (1914–1996) 

• Chevrolet Acquisition: Following Maxwell-Briscoe’s bankruptcy, the Chevrolet Motor Company acquired portions of the site in 1914 and 1915.
• General Motors Merger: When Chevrolet merged with General Motors in 1918, the plant became the GM Assembly Division, Tarrytown. It would eventually become the largest GM assembly plant east of the Mississippi.
• World War II: During the war, production shifted to military aircraft. As part of the Eastern Aircraft Division, the plant built wing assemblies and other components for the Grumman TBF Avenger torpedo bomber, employing roughly 10,000 workers, including 2,900 women.
• Post-War Prosperity: In 1963, the plant celebrated a major milestone by producing the 50 millionth Chevrolet, a gold-colored Impala SS. At its peak, the plant provided nearly 50% of the village's tax revenue. 

 

Closure and Redevelopment

• Plant Shut Down: The facility closed in June 1996. Its age was a primary factor; the multistory, land-constrained site could not be efficiently modernized for new production methods. The final vehicles produced were the "APV" minivans: the Chevrolet Lumina APV, Pontiac Trans Sport, and Oldsmobile Silhouette.
• Demolition: The massive complex was demolished in 1999.
• Edge-on-Hudson: Today, the 96-acre site is being transformed into a mixed-use development called Edge-on-Hudson, featuring residential units, retail space, and a waterfront park.
