It links the eastern shore of the lake to the center of the city, through the Monumental Axis.

The decks are suspended by steel cables alternating at each side of the deck, interlacing in a twisted plane. The entire structure has a total length of 1,200 metres (3,900 ft), and it was completed at a cost of US$56.8 million .[4] The bridge has a pedestrian walkway and is accessible to pedestrians and bicyclists.
