SAO PAULO (Reuters) – Brazilian highway operator CCR SA said on Friday that vehicle traffic on its roads reached its highest level since mid-March, as state authorities throughout the nation begin to relax quarantine measures.

In a securities filing, it said traffic in the period from May 29 to June 4 was only 14% below the same period a year before. In the previous reporting period, traffic had been off 21% in annual terms, and in mid-April traffic was off 37%.

Among the highways administrated by CCR is the Via Dutra, the main connector between Sao Paulo and Rio de Janeiro.
