The treaty provided for the construction of the railroad MadeiraMamore to facilitate the flow of Bolivian exports and the construction of the bridge is seen as a continuation of this commitment.

Construction of the bridge is scheduled to begin in 2025 and end in 2027with an initial cost estimated at R$300 million. However, the notice released by the DNIT estimates the overall value of the works at around R$430 million.
