The PB-066 highway, which connects the municipalities of Ingá and Itambé in Paraíba, was highlighted as the third worst stretch of highway in Brazil in a report by the National Transportation Confederation (CNT). This ranking is part of the CNT's 2025 Road Survey, which assesses the condition of highways in the country. The report indicates significant concerns regarding road safety and infrastructure quality across Brazil's highway system.

In 2025, Paraíba experienced 1,977 accidents on federal highways, leading to 141 fatalities, which averages out to seven deaths for every 100 accidents reported. Such high accident rates raise alarms about the safety conditions on highways like PB-066, emphasizing the need for urgent governmental interventions and improvements to road infrastructure. The statistics reflect a broader issue concerning traffic safety in Brazil, significantly impacting local communities and their connectivity.

Additionally, the CNT's research reveals substantial structural problems with the highway network in Paraíba, with 72.2% of highways showing some form of deficiency. Notably, 53.8% of the surveyed highways face pavement issues, 72.7% suffer from inadequate signage, and 77.2% exhibit geometric deficiencies, such as improper curves and lack of shoulder space. The state’s deteriorating road conditions not only pose risks to drivers but also impede economic development and mobility within the region.
