#CaltransCrews are constantly at work making our highways safer for the traveling public, removing litter and encampments, like this one at SR-99 @ the Calaveras River, last week. And they work with local partners to provide needed services to impacted individuals.

This might not seem like much trash, but Caltrans often fills dozens of bags with trash like this strewn for a mile or more, like recently along I-5 near the Lathrop Road exit in SJ County. Please keep a bag in your car to collect your litter and avoid it spilling out. #CleanCA
