. This medal is awarded "for a single, recent outstanding achievement showing harmony with the environment, aesthetic merit and successful community participation".

This bridge was also awarded the "Premio Abcem 2003" (ABCEM Award) – Best Steel Work of the Year, Bridges and Highway Overpasses Category, granted by the Brazilian Metal Construction Association (Associação Brasileira da Construção Metálica, ABCEM).

The bridge architectural design looks similar to a pedestrian walkway in the Port of Nagoya Public Aquarium located at 35°05′25"N 136°52′47"E. However architectural design also included structure shapes and solutions that step away from that footbridge.

Dimensions

The main characteristics of the structure are:
  • Total length: 1,200 m
  • Deck Width: 24 m (three lanes in each direction)
  • Lateral sideways for pedestrians and bicycles: 1.5 m (on each side)
  • Rise: 60 m
  • Clearance: 18 m
  • Arch span: 240 m for each of 3 spans
