Motorists can anticipate the following traffic pattern changes:

  • East Entrance: This access point will be closed. A temporary east entrance will be available nearby and closer to the casino. Access to and from the temporary east entrance will be open for both directions of travel on US-95.
  • West Entrance: Drivers heading southbound on US-95 will not be able to access the plaza at the west entrance. However, this entrance will be accessible for travelers on northbound US-95 to and from the plaza.
