Dear Roosevelt Island Community: Due to hazardous roadway conditions caused by the ongoing storm, the Helix is now temporarily closed to non-essential vehicular traffic until further notice. This measure is being taken to ensure public safety and to allow crews to address roadway conditions. Please also note that New York City has issued a travel ban for all vehicles beginning at 9:00 PM tonight. Please stay off the roads and avoid any unnecessary travel.  Thank you for your cooperation. – PSD
