The Alliance for Infrastructure Reuse and Redevelopment (AIRR) is a coalition of infrastructure reuse projects across the nation that are reclaiming underutilized and neglected infrastructure including abandoned railways and highways and polluted riverfronts and waterways and transforming them into new public space. AIRR projects are leading the way in bringing underserved communities together, increasing equitable access to healthier public spaces for residents, mitigating pollution and creating new connections across cities.
