The eyes of the sports world will be glued to Arlington as the Cowboys and Texas Rangers host home games, but that also means a traffic nightmare.
150,000 football and baseball fans are expected to descend on Arlington Sunday.
The Dallas Cowboys host the New England Patriots at AT&T Stadium, kickoff is scheduled for 3:25 p.m.
The football game is expected to end just as the Texas Rangers host their first home game in the American League Division Series. First pitch at GlobeLife Park is slated for 7:10 p.m.
Fan turnout is expected to be high as the Rangers hope to sweep the Blue Jays.
The Cowboys, Rangers and Arlington police urge fans to be prepared, leave early and plan to get to the game hours before they start.
Some fans got the message, NBC DFW caught up with Cowboys fans who were tailgating at 8 a.m. Sunday.
To top it off parking will be at a premium.
Unlike other games, there will be no cash lots for Cowboys fans, only ticket holders with season parking passes will be able to park in cash lots.
Parking lots will open at 2 p.m. for Rangers fans. Normal cash lots will be available, but fans must show parking attendants their game tickets.
Six Flags Over Texas and Six Flags Hurricane Harbor will open their parking lots for both Cowboys and Ranger fans. Six Flags reminds fans that Fright Fest is in full swing and the amusement park will be busy as well.
Arlington police say they plan to have plenty of officers on duty.
And a reminder, to keep traffic flowing, police may direct traffic in different directions than normal and GPS systems may offer directions that conflict with changed traffic patterns.
Bottom line, leave early and pack your patience.
