In 2012, a record 18 people threw themselves off the bridge to their deaths, while 43 others attempted to do so but survived. There were 18 deaths reported in both 2014 and 2015. In 2014, 74 people were stopped by the Port Authority police, while the next year, another 86 people were stopped by the Port Authority police. In 2016, there were 12 reported deaths, a decrease from previous years, while 70 people were stopped by the Port Authority police. In 2017, the Port Authority proposed equipping a two-person Emergency Services Unit team with harnesses to prevent suicides from the bridge. Following 15 reported deaths and 68 attempts in 2017, the Port Authority installed protective netting and an fence along each upper level sidewalk. The netting partially overhangs the sidewalks in order to prevent potential jumpers from scaling the fence directly. The southern sidewalk was closed from September to December 2017 so that a temporary fence could be installed there. Once the temporary fence had been erected, the permanent 11-foot-high barrier was constructed on the northern sidewalk, followed by the permanent barrier on the southern sidewalk.
