Goiânia Viaduct Project Nears Completion After Delays and Rework
The construction of the viaduct at the intersection of Avenida Leste-Oeste and Avenida Castelo Branco in Goiânia's Jardim Leblon neighborhood is expected to be finished within 90 days, according to the Goiânia City Hall. The project, managed by the Municipal Secretariat of Urban Infrastructure (Seinfra), entered a new phase on the 25th with the opening of the side roads for earthworks, base, and sub-base services, as well as the commencement of asphalt application. Mayor Sandro Mabel announced that the first side road, heading towards the city center, should be open to traffic in early August, even before the viaduct's full completion. The second side road is anticipated to be delivered 30 to 40 days later. The municipality stated that its own teams, machinery, and trucks are carrying out the work. The mayor highlighted that this section is in its final stages, with asphalt application to follow priming next week, a strategy also being used on Avenida Leste-Oeste in the Setor Negrão de Lima to maintain city traffic flow. The viaduct construction began on May 15, 2023, under former mayor Rogério Cruz, with an initial budget of R$14 million and a 240-day completion forecast. However, work was halted in July 2024 due to contractual issues and resumed in September after the city government issued a new service order. The interruption was attributed to outstanding expropriation matters and financial difficulties faced by the original contractor. At the time of resumption, approximately 80% of the project was already completed. Seinfra is also conducting studies and structural reinforcement for the viaduct, having ruled out demolition. Engineering specialists have devised a technical solution for its safe recovery. The works are divided into four stages: relocation of the storm drain, earthworks, paving of the side roads, and finally, the installation of traffic light signaling by the Municipal Secretariat of Traffic Engineering.
The Goiânia viaduct project's timeline and budget overruns, stemming from contractual disputes, expropriation issues, and contractor financial problems, highlight common challenges in large-scale urban infrastructure development. The municipality's decision to resume work with its own resources and a revised plan, including phased traffic release, suggests a focus on mitigating public inconvenience and demonstrating progress. The structural reinforcement and recovery approach, rather than demolition, indicates a pragmatic response to sunk costs and resource constraints. Looking ahead, such projects underscore the importance of robust contract management, thorough due diligence on contractor financial stability, and contingency planning for unforeseen legal and economic hurdles to ensure timely and cost-effective delivery of public works, especially in an era of increasing infrastructure demand and potential supply chain volatility.
