Even on a regular day, no matter the hour, there are at least 6 cop cars hanging out at the entrance of the Holland tunnel. The only time I ever saw just one was during the pandemic.
oh, and until 2025, the Holland Tunnel lane to NJ is closed at night for repairs. It reopens at 5:30 am. Thus this tunnel is open only part time.
The terrorists aren’t blocking much. I think one can still drive into NY but not to NJ.
