RIO-NITERÓI BRIDGE

REINFORCEMENT AND EXPANSION

RIO-NITERÓI BRIDGE
LOCATION:
Ponte Rio-Niterói - Rio de Janeiro, Brazil

CLIENT:
EcoPonte / Ecorodovias
Following the preliminary analysis, the reinforcement and expansion of the Rio-Niterói bridge was designed and implemented, accompanied by an executive project to expand the three access ramps to the city of Niterói, including structural adaptation of the existent bridges, and calculation of the related future maintenance costs.

The intervention consisted of a technical inspection for a preliminary assessment of the condition of all the bridge’s structural elements: deep foundations, pillars, support equipment, deck and joints, for the main structure and all the access ramps.
All the pier protection elements were inspected and steel replacements were designed.

Reinforcement was designed for the concrete box beams using external post-tensioning (reinforcement applied to over 100 of the bridge’s spans).
