Sources: 7. Developments: 2. Discussions regarding infrastructure improvements for the BR-101 highway in Santa Catarina, specifically the Morro dos Cavalos section in Palhoça, have progressed toward regulatory authorization. Initially, Senator Esperidião Amin and Transport Minister George Santoro met to discuss urgent safety works, including the construction of tunnels to mitigate high fatal accident rates. At that stage, the project's execution depended on the National Land Transport Agency (ANTT) ratifying an agreement with the concessionaire. Following these discussions, the ANTT authorized an update to the R$ 1.9 billion tunnel project intended to address regional traffic congestion. However, the concessionaire Arteris Litoral Sul indicated the project remains in a “protocol of intentions” stage, noting that implementation faces complex legal and contractual discussions, including the potential return of the highway segment to the Federal Government. ## Timeline ### 2026-08-18: Morro dos Cavalos tunnel project receives ANTT authorization ANTT has approved an updated project for the R$ 1.9 billion Morro dos Cavalos tunnel on the BR-101, though implementation remains distant due to ongoing contractual discussions. 3 sources. https://clstr.news/cluster/morro-dos-cavalos-tunnel-project-receives-antt-authorization ### 2026-08-11: BR-101 safety works discussed by Senator Amin and Transport Minister Senator Esperidião Amin and Transport Minister George Santoro are discussing urgent safety works, including tunnels, for the high-accident Morro dos Cavalos section of the BR-101 in Santa Catarina. 5 sources. https://clstr.news/cluster/br-101-safety-works-discussed-by-senator-amin-and-transport-minister --- Cite as: BR-101 highway infrastructure projects in Santa Catarina.
