The Pavement Condition Index, or PCI, is tracked by the Metropolitan Transportation Commission, the regional transportation planning and funding agency that monitors the condition of Bay Area roads. San Francisco's PCI score for 2020 hit 75 out of 100, exceeding the region-wide average of 67. A PCI score of 75 puts the roads collectively in "good" condition, requiring mostly preventative maintenance. A score of 100 is assigned to a newly paved road, according to the announcement.
