From October 16 – 18,  the High Line Network convened the largest gathering of North American infrastructure reuse project leaders in our first ever symposium, Beyond Economic Impact: Charting the Field of Infrastructure Reuse. As cities grow, the pressures of density and high costs of land are increasing the need for public green space. Infrastructure reuse projects (for example, highways, railways, bridges, industrial riverfronts, or waterways) provide an opportunity for a new generation of parks, which frequently cite the High Line as an example of what’s possible.
