A 2022 document already indicated the risk of collapse on the Anita Garibaldi Bridge, and the company wants to limit maximum load

New routes facilitate access to Laguna after closure of the Anita Garibaldi Bridge A 2022 document obtained by the NSC already pointed out flaws in the structure of the Anita Garibaldi Bridge, in Laguna, in the south of Santa Catarina, which began to be closed for emergency repairs on Thursday (9). In the report, the structure's concessionaire points to the risk of collapse. The ViaCosteira concessionaire said in a note that it "maintains a permanent monitoring and technical monitoring program" of the bridge and that "the intervention currently being carried out arises from a different situation than that recorded in 2022, that is, it is in the same section, but at a different point" (check the full note at the end of the report). ?Click and follow the g1 SC channel on WhatsApp The 2022 document, dated October 10th and addressed to the National Land Transport Agency (ANTT), refers to a survey carried out on the bridge. She identified problems in the structure of the central span and lateral span, in addition to the rupture of four bars that connected the lower slab to the bridge blocks (read the technical terms below). The concessionaire stated in a statement that it carried out the necessary interventions, with specialized technical support, and reestablished the expected conditions. This year, on June 25, a new communication from the concessionaire indicated, following other reports, the need for temporary load restrictions on the bridge. The limitation would be 10 tons per single axle of the truck with four tires. The measure would apply to both directions of the bridge for a period of around six months, until the problem diagnosis phase is completed. Another report, from July 8 of this year, pointed to the breaking of cables between structures in the central span, which was the reason for the closure that began on Thursday. A communication from the concessionaire dated July 6 pointed out that it has been searching since 2022 for documents that detail the construction of the bridge and highlighted that “the recovery of the executive history of the work is important for a more conclusive assessment of the causes of the occurrences and the structural behavior of the bridge”. Closure of the Anita Garibaldi Bridge enters its 4th day with the use of ferries to ease traffic Anita Garibaldi Bridge was closed for cable maintenance Anita Garibaldi Bridge is closed for emergency repair 2022 document points out problems and risk of collapse on the Anita Garibaldi Bridge, in Laguna Reproduction What the 2022 document says The document points out the following problems on the bridge: opening between staves 06-07 and 14-15 of the central span 35C staves 08-09 in the lateral span 35L rupture of the four bars that connect the lower slab between staves 06-07 Current closure is scheduled until July 20 The decision for the current closure was taken after a special inspection carried out this week identified an anomaly in one of the structure's support cables. The technical report was completed on Thursday. According to the concessionaire, there was a partial rupture of internal wires in just one of the 90 cables that make up the bridge's structural system. The cable did not break completely, but the concessionaire chose to close the structure to carry out the repair and carry out further analysis. Traffic at the site was blocked in both directions to carry out this work. The flow of vehicles in the south direction was interrupted on Thursday night. The north direction was in half lane until around 4pm on Friday (10), when it was also closed. The work at the site is expected to last 10 days, until July 20th. The closure has generated queues at the site. The Federal Highway Police (PRF) reported that there were 6 kilometers of congestion late this Tuesday morning (14). How was the problem discovered? The concessionaire carries out frequent visual inspections on all works on BR-101 and promotes two special inspections per year on the Anita Garibaldi bridge. The first detailed inspection of 2026 took place in April and found no irregularities. The second, carried out in July, identified the partial rupture of the internal wires of one of the cables. According to the concessionaire, the decision to close the structure was taken immediately after completing the technical report. Traffic diversions during Southbound activities (Porto Alegre) - The diversion now starts at km 311 of BR-101. Vehicles will be directed to the marginal road and will follow the Cabeçudas Bridge to the Bananal neighborhood, from where they can return to the express lane. Northbound (Florianópolis) - Vehicles must access the detour at km 315 (Bananal neighborhood) following the marginal road towards Ponte de Cabeçudas. From this point, the route continues to the vicinity of Posto Lagoa, along the marginal road, which will temporarily operate in two-way during the period of the works. Anita Garibaldi Bridge Laguna City Hall/Disclosure Bridge was inaugurated in 2015 With 2.8 kilometers long along BR-101, the structure inaugurated in 2015 is considered one of the city's main postcards and an engineering landmark as it is one of the largest curved cable-stayed bridges in Brazil. The bridge's central span is 400 meters long and is suspended in the air by 60 steel cables (see below). The bridge also has two towers that rise more than 50 meters high and contribute to the stability of the structure, according to the municipality. What the concessionaire says Check out the concessionaire's full note below: ViaCosteira clarifies that, since the beginning of the concession, it has maintained a permanent monitoring and technical monitoring program for the Anita Garibaldi Bridge, as well as other special works of art under its administration. This work is carried out through periodic inspections and assessments carried out by specialized teams. It should be clarified that the intervention currently being carried out arises from a different situation than that recorded in 2022, that is, it is in the same section, but at a different point. At the time, after a special inspection of the structure, repair needs were identified and the Concessionaire carried out the necessary interventions, with specialized technical support, reestablishing the expected conditions. During one of the bridge's continuous inspection and monitoring routines, carried out last week, a specific anomaly was identified in one of the internal tendons – a set of high-strength steel wires – which indicated the need for repair. As a preventive measure, and aiming to guarantee the safety of drivers and teams involved, it was necessary to temporarily block the bridge completely to carry out the work, with the implementation of traffic diversions in the south and north directions of BR-101. The blockage allows access for the teams and equipment necessary to carry out maintenance, since the services are carried out in the internal structure of the bridge. The Concessionaire reinforces that the identification of the anomaly is a direct result of the permanent monitoring carried out in the structure and that all measures adopted follow strict engineering and safety criteria, with the aim of preserving the integrity of the Anita Garibaldi Bridge and ensuring everyone's safety.
