It is being replaced by a viaduct with two pillars located parallel to the direction of the flow, with three spans formed by beams.??The central opening is formed by two beams of 25,60 m length and the lateral compartments with a beam of 11.44 m and a length of 13.67 m each to compensate the skew of the pillars to the axis of bridge. The two abutments are newly built, of concrete mass, to achieve sufficient stability and allow the demolition of the current board with sufficient security.
