About This Bridge's Photo-Documentation

This expressway overpass bridge was photographed by HistoricBridges.org while driving on the associated highway. As such, only overview photos from the expressway lanes are available. Although the many old overpasses on New York State parkways are similar in design and appearance, there is a lot more variety in design and aesthetic details than on modern overpass bridges. Providing a full HistoricBridges.org style detail-oriented photo-documentation is not feasible due to cost and time. However, these photos are intended to generally document the parkway and the design of the bridge. The parkway and its bridges are historically significant as documenting the earliest attempts to provide a limited access highway system to facilitate the rapid movement of large volumes of traffic.

About New York State Parkways

In the early 20th century as motor vehicles rapidly grew in popularity and population, the need to provide more efficient roads became clear rather quickly. One of the early efforts to this effect was the development of limited access highways, the earliest forms of what would eventually evolve into modern expressways and interstate highways. These early roads were often called parkways, although the term superhighway was sometimes used too. Like modern expressways these roads had grade crossings separated by overpass bridges, and access was typically limited to ramps provided at some crossings. However, compared to modern expressways, the design speeds were much lower, travel lanes were narrow, and overpasses were not usually designed with clearance suitable for modern trucks. Also, as the name implies, these "parkways" were designed with a much higher level of attention given to beauty including in bridge design, as well as landscaping (trees in the medians for example). Overpass bridges in the greater New York City region and elsewhere in New York State typically used concrete rigid-frame or concrete arch bridges faced in stone. This choice of structure type matches many other parkways built in the United States in this period. The use of rigid-frame and concrete arch bridges for limited access highway overpasses tends to appear on only the oldest of freeways, because the design was not economical for the longer spans employed on more modern freeway systems.

In New York State many of the parkways are associated with Robert Moses.
