Infrastructure maintenance and expansion projects are being conducted across various highways in Paraná, Brazil.

Initial works included controlled detonations for duplication and restoration on the PR-445 highway, requiring a ‘stop-and-go’ traffic system. Additionally, the Department of Highways of Paraná (DER/PR) began pavement conservation on the PR-473 as part of the R$ 63.34 million ProMAC program, which aims to maintain regional roads through February 2029.

Subsequent operations expanded to include traffic changes on the BR-469 near the Foz do Iguaçu International Airport to facilitate highway duplication. In the southwest region, nighttime pavement recovery works involving milling and recomposition were initiated on highways PR-483, PR-180, and PR-280, utilizing alternating passage systems to manage vehicle flow.
