NYC will invest $50 million to install 1,500 security 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.

Currently, there are only 50 spots throughout the five boroughs where permanent public bollards have been installed, said the New York Daily News.

"We have witnessed an increase in pedestrian injuries and fatalities as vehicles are increasingly being used as weapons to carry out attacks," Rep. Adriano Espaillat said in a statement. "Safety bollards saves lives and help in our efforts to strengthen safety measures along sidewalks, popular tourist destinations, and high pedestrian traffic areas."

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