New York Governor Andrew Cuomo and New Jersey Governor Chris Christie are announcing increased security across their two states.
The measures are being taken in the wake of increasingly active terrorist groups overseas.
Cuomo said Wednesday they are not linked to a specific threat targeting the New York City region.
The governors appeared at 7 World Trade Center to sign a bistate memorandum of understanding. They say it will lead to further cooperation between the two states’ law enforcement agencies.
More uniformed officers are set to be deployed at transit hubs and on trains. Security also will be increased at the area’s bridges, tunnels and ports.
The men did not provide a cost for the security expansion. They said it would remain in place for as long as needed.
