Documenting New York's Bronx River Parkway, USA

Abstract

New York's Bronx River Parkway was a seminal development in the history of the modern motorway. Conceived in 1906 and completed in 1925, the parkway was the first public project to provide a large-scale demonstration of the essential components of modern motorway design: strict limitations on access and egress, grade-separated interchanges, flowing horizontal and vertical curvature geared toward safe and pleasurable high-speed travel, and a broad publically owned right-of-way for better control of the roadside environment and greater flexibility in alignment and location. The Bronx River Parkway was embraced by the motoring public, hailed by contemporary design professionals, and celebrated by subsequent historians. In recognition of the parkway's significance, the Historic American Engineering Record (HAER) conducted a multi-disciplinary documentation project in 2001. HAER produced large-format photographs, a detailed historical report, and measured and interpretive drawings depicting construction details, development processes, and design concepts. The project was part of a larger effort to document historic American roadways including National Park Service park roads and parkways, Columbia River Highway, Merritt Parkway, Taconic State Parkway, and the Arroyo Seco Parkway/Pasadena Freeway. This documentation can serve as a valuable model for future efforts to document and interpret twentieth century motorways and other civil engineering resources.
