Cars are not allowed in Venice. So, once you drive 2.5 miles across the lagoon on the Deck della Libertà, also called the Freedom Bridge, you’ll park in one of the expensive garages at Piazzale Roma. While stretching your legs, enjoy this first view of the City of Bridges from across the Ponte della Costituzione. The Constitution Bridge was built in 2008, making it the fourth and newest to span the Grand Canal.
