This proposal to render the disused Bloomingdale line accessible to the public consists in proposing a strategy that would render it continuous with the ground and accessible from the street level. Taking clues from the Lindenmeyer algorithmic growth system, the Bloomingdale trail is interpreted as a linear quantity that accepts branching or splitting as a condition of its evolution – providing the possibility for public access at any moment along the trail. Bridges are understood as the detail of this configuration; the specificity of their structure allows for variable spans each time the line encounters streets, avenues or boulevards.
To make the bridges an economically viable project, each bridge is made with repeatable component of bent steel tube, making it possible to mass-produce them. The bridges are modeled in a parametric environment that keeps track of the large amount of information that describes the variation of each bridge and its associated componentry.
