Spanning 5 facades and ranging 5-7 stories tall, the 85,000 sq ft How Philly Moves mural at PHL International Airport is the biggest piece of public art in the city, and one of the largest in the world. Drawing from imagery from the How Philly Moves community photo sessions, the mural celebrates Philadelphians who love to dance. The mural is visible from both I-95 and the SEPTA airport regional rail line. There is no one perfect vantage point to take it all in, but the rental car parking lots offer some of the best places for pedestrian viewing angles
