Traffic was “mostly moderate” throughout the day until about 7 p.m., when there was an increase in congestion on Route 99, Procopio said.

Troopers also assisted casino security with minor incidents, such as minors on the gaming floor, arguments, medical aid, and crowd control.

The crowds were said to be heavy throughout the day and night.
