On October 31 , 2017 , a man intentionally drove a pickup truck for a mile through the park 's bike path between Houston Street and Chambers Street , killing eight people and injuring at least 11 . Most of those who were hit were bike riders . The incident , considered the city 's first deadly terrorist attack since the September 11 attacks , was committed by a man who allegedly pledged allegiance to the Islamic State of Iraq and the Levant terror group . After the attack , several media sources wrote about how easy it was to drive down the bike lane , either by accident or on purpose , referencing the lack of bollards and the previous fatalities caused by drivers on the bike path . City and state officials also worked on ways to improve the bike lane 's safety measures , and two days after the attack , the city started placing temporary concrete barriers on the path . The temporary barriers were installed by November 3 . Permanent safety bollards were installed starting in July 2018
