Part of Mayor Bill de Blasio’s ‘Vison Zero’ plan was to make streets safer for pedestrians. As a result, the area where Broadway and Columbus converge has been reorganized. The intersection has been the site of 144 crashes with serious injuries and one fatality between 2008 and 2012 according to City Council member Helen Rosenthal. As a result, the “suicide knot” has had its traffic flows reorganized to the consternation of some drivers.
