ADOT officials say heavier traffic can be expected on westbound I- 10 in Phoenix as well as Loop 101 in Glendale Friday afternoon,prior to the preseason game between the Arizona Cardinals and Dallas Cowboys at 7-pm. Drivers should expect busier than normal conditions due to a mix of football and regular commuting traffic heading towards the West Valley. Fans traveling to the game should allow extra time and try to arrive in the area near the stadium early. Parking lots will open four hours before kickoff.
