 In February 2011 , a lawsuit was filed by the Yorkshire Towers at 86th Street over the location of two proposed Second Avenue Subway entrances that were located right in front of the building but facing away from its semicircular driveway . The quality of life for building tenants was allegedly to be destroyed if the entrances were to be built in the location ; however , the lawsuit was later dismissed . In an unrelated 2012 controversy , some residents in the 72nd Street station area claimed to have come down with a " Second Avenue cough " caused by dust from construction , and local doctors saw that the air quality of the area had decreased while nasal sicknesses had increased . The MTA tried to combat this by creating new structures and using other methods to reduce dust inhalation . The MTA prepared a report that said in the 86th Street station area " all monitored concentrations were below the established benchmark levels " .
