BRIDGE OVER THE TIETÊ RIVER

SP-225 HIGHWAY – JAÚ / PEDERNEIRAS (SP)

CHALLENGE Build a new 238m-length bridge simultaneously with the demolition of the old bridge, without explosives and preventing debris from falling into the river and without interrupting the heavy river traffic of the Tietê River – a significant challenge.
SOLUTION We planned the bridge demolition in phases and using different resources due to the technical and environmental requirements. A barge was positioned to recover all the demolition material. The operation employed a hydraulic hammer, Aspen metal truss girder launcher and a Darda concrete crusher, in addition to 30 professional divers to cut the submerged bearings on the riverbed.
