In late September 2026, road maintenance projects were scheduled across the states of São Paulo and Minas Gerais. These works included pavement recovery, pothole repairs, and signage updates on the Fernão Dias Highway (BR-381) and various roads in southern Minas Gerais, such as MGC-491 and BR-146.

By October 2026, the focus shifted toward traffic management and safety regulations. The Department of Highways of Minas Gerais (DER-MG) implemented restrictions on heavy vehicles during the Nossa Senhora Aparecida holiday. Under Ordinance No. 4.242/2026, large cargo vehicles exceeding specific weight and dimension limits were prohibited from circulating on certain state highways during designated periods to improve road safety and traffic flow.

Specific details for the holiday period on October 12, 2026, include restrictions on large vehicles such as ‘bitrens’ and ‘rodotrens’ on highways including MG-010, MGC-135, and MG-050. These prohibitions are scheduled for Friday (9/10) from 16:00 to 22:00, Saturday (10/10) from 06:00 to 12:00, and Monday (12/10) from 16:00 to 22:00.

Additionally, the holiday will trigger various public service closures. State public schools will be closed from Monday (12/10) through Friday (16/10). Integrated Service Units (UAIs), Ipsemg, Hemominas, and Farmácia de Minas will close on Monday, October 12, with most resuming operations on Tuesday. Cultural sites, including several state museums and the Palácio das Artes, will also close on Monday, though the Palácio da Liberdade will remain open.
