Mayor Bill de Blasio is beginning the new year looking to protect pedestrians from potential vehicle attacks in New York City.

The mayor said the city will invest $50 million to install 1,500 permanent protective metal barriers, known as bollards, to create safer sidewalks and pedestrian plazas at key locations.

The NYPD and Department of Transportation are surveying sites to determine where the bollards work best.

The rollout will begin in March. All of the barriers are expected to be installed over the next five years.
