Local law enforcement officials will be busy spotting drunk drivers this Super Bowl weekend. Metro Police plan a sobriety checkpoint near Cheyenne Avenue and Tenaya Way in the northwest valley, which saw 26 DUI arrests and 146 accidents in 2010. The checkpoint will run from 7 Sunday night until early Monday morning. Metro will also join forces with the Nevada Highway Patrol and Henderson police to step up DUI enforcement before the big game with saturation patrols on undisclosed Henderson roads between 6 Saturday night and early Sunday morning. Authorities urge football fans to designate a driver or arrange another form of transportation if they plan to drink during the big game.
