The Steuben House Commission was created in 1926 to purchase Baron Steuben's home at New Bridge. The State took possession of the historic mansion and of ground for $9,000 on June 27, 1928. It was renovated and opened as the museum headquarters of the Bergen County Historical Society in September 1939. The Steuben House is listed on the New Jersey and National Register of Historic Places. The Bergen County Historical Society continued stewardship of the site by purchase of land between the Steuben House and the encroaching autoparts yard in 1944. In 1954, the Society was able to persuade the County of Bergen to divert the planned 4-lane highway to the north of the site instead of alongside the historic site. The highway bridge opened in 1956 and the one-lane 1889 swing bridge was closed to vehicles. It remains open for pedestrians.
