The city started rebuilding the plaza in 2010, hiring the design and landscaping firm Snøhetta to permanently replace Broadway's roadway with custom-made granite pavers and benches. By December 2013, the first phase of the Times Square pedestrian plaza had been completed at the southern end of the square in time for the Times Square Ball drop on New Year's Eve. The project was originally intended to be completed by the end of 2015. The entire project was finally completed just before New Year's Eve 2016. Some safety bollards were also installed as part of the renovation to prevent vehicular attacks or collisions on the sidewalk. After a fatal 2017 car crash, there were calls to install more bollards along Times Square.
