MARIPOSA COUNTY — Caltrans recently completed a $5.4 million project rehabilitating eastbound and westbound Highway 140 (SR-140) in the area of the Ferguson Fire scar.
Caltrans says the work was needed after the Ferguson Fire burned through the region during the summer of 2018. The project included replacing 17 culverts (underwater drainage systems) and performing 12 miles worth of hazardous tree and vegetation removal and slope scaling, according to Caltrans. Slope scaling refers to working on roadside slopes, including implementation of erosion control measures, to mitigate future instances of mudslides and debris flow during storms.
The Ferguson Fire started July 13, 2018, in Mariposa County and burned more than 96,900 acres, causing power outages, road damage and road closures. Burnt vegetation and trees exposed slopes to erosion, mud flows and rock falls.
The agency notes that it appreciates the cooperation and patience of local residents and travelers during this process.
