There are several reasons for Sky Bridge 721 to be named as it is. First, it reflects the length of the bridge, which is 721 meters. Second, it is built 95 meters above the valley, which makes you feel like you are somewhere between the sky and the earth.
Due to safety regulations, only 500 visitors are allowed to remain on the bridge concurrently. Another ratio that is carefully observed by those in charge of the bridge is the weather forecast. If the wind blows at a certain rate, the bridge is closed due to security concerns.
The bridge, located above Kralicky Sneznik mountain, was constructed within a year. It opened to visitors this May.
