The Benjamin Constant Bridge (Portuguese: Ponte Benjamin Constant), also known as Metallic Bridge (Ponte Metálica), is a suspension structure located on Sete de Setembro Avenue that crosses the Igarapé do Mestre Chico between the Cachoeirinha and Centro neighborhoods, in the Brazilian city of Manaus, capital of the state of Amazonas.

[1] To provide greater safety for the population, the then state governor Eduardo Ribeiro decided to build the bridge in iron and steel.

[1] The bridge, which is considered one of the most beautiful in Brazil and one of the most imposing in Manaus, was built between 1893 and 1895 with parts imported from England, supervised by engineer Frank Hirst Hebblethwait and inaugurated on September 7, 1895.

[1] Without renovation for almost twenty years, on January 25, 2005, the bridge was closed to heavy vehicle traffic due to the risk of collapse.

- Econcel was responsible for carrying out the work, which, in addition to state resources, was funded by the Federal Government and the Inter-American Development Bank (IDB).
