Description: Pavement maintenance protects the taxpayers’ investment in the highway system and can reduce long-term costs by postponing the need for more expensive roadway rehabilitation. Poorly maintained roadways increase costs to motorists for vehicle repair, costing drivers in Los Angeles or San Jose an average of more than $700 a year for instance. There is now a backlog of $587 million in pavement maintenance work. We recommend Caltrans refocus its maintenance efforts by developing an investment plan for highway maintenance. We also recommend Caltrans develop performance measures that link the state’s investment to the resulting quality of the highway system.
