Authorities will shut down a seven-mile stretch of border near the Pope’s mass location. They estimate upwards of 1 million people will gather on both sides to try and enjoy a glimpse of the pontiff.

Another 60,000 people will gather in his honor at the Sun Bowl at the University of Texas at El Paso.

Maldonado added, “It’s the movement of the people that’s going to create gridlock and public safety issues.”
