Viaduto da PR-151 em Palmeira entra na reta final das obras
As intervenções de melhoria na PR-151, situada na região dos Campos Gerais, alcançaram um patamar avançado com a proximidade da conclusão da nova estrutura elevada em Palmeira.
Avanços na infraestrutura urbana e viária Para viabilizar a estrutura, o trecho principal da estrada foi elevado, permitindo que o fluxo de veículos dos arredores — abrangendo as vias XV de Novembro, Manoel Ribas, Daniel Mansani e a Avenida Nacim Bacila — passe a ser direcionado por meio de duas passagens inferiores.
Pavimentação e acabamentos finais Neste momento, as equipes trabalham na aplicação da pavimentação nas pistas e nos acessos do viaduto. O cronograma prevê ainda a implementação da sinalização vertical e horizontal, a colocação de equipamentos de proteção viária, a implantação de iluminação pública e demais arremates necessários.
Modernização com pavimento de concreto Enquanto isso, os trabalhos prosseguem ao longo do restante do segmento rodoviário com serviços de terraplenagem para ampliação da largura da pista. Essa etapa viabiliza a criação de acostamentos, faixas adicionais e a expansão das faixas de rolamento atuais.
Técnica de engenharia aplicada O projeto utiliza o método conhecido como whitetopping, no qual a antiga base asfaltica recebe preparação para servir de suporte a uma nova camada de concreto rígido. Com 23 centímetros de espessura, essa tecnologia assegura uma durabilidade estimada em duas décadas.
Infraestrutura complementar e prazos O pacote de melhorias também engloba a modernização da drenagem pluvial, sinalização renovada, revegetação das margens com plantio de grama e outras intervenções acessórias.
Cronograma de entrega O contrato abrange uma extensão de 32,71 quilômetros da rodovia, desde o cruzamento com a PR-438, em Ponta Grossa, até a interseção com a BR-277, em Palmeira. Com aproximadamente 70% do cronograma total já cumprido, a conclusão de todo o projeto está programada para julho do ano seguinte.
