Roosevelt Island is served by Police, Fire and EMS services which are based in Queens. Access to the Island is by bridge at 36th Avenue and Vernon Boulevard.
Should there be a scheduled interruption in bridge service - for repairs or in the rare cases when it is raised for river traffic - a fire truck, a police vehicle and an ambulance are dispatched to the Island where they are on call in case of any emergency.
Public Safety also has a procedure in place to bring firefighters and police officers to the Island via tram, subway and RIOC vehicles to ensure rapid response. Public Safety regularly schedules drills with the NYC Fire and Police Departments on emergency Tram procedures.
