Bumpy Roads Ahead: America’s Roughest Rides and Strategies to Make our Roads Smoother (July 2015) - The National Transportation Research Group’s July 2015 report compared roads among cities with urban populations between 250,000 and 500,000. It found that Santa Rosa Has Nation’s Third Worst Roads for a Medium-Sized City.
Using Federal Highway Administration data from 2013 the group concluded that Santa Rosa has the third highest share of roads in the nation that are rated poor (chart 5, page 15). Only 10 percent of Santa Rosa’s roads and highways are considered to be good; 12 percent are fair, 29% are mediocre and 49% are poor. For purposes of this study an urban area includes the city and its neighboring suburban areas, meaning that the county roads adjacent to Santa Rosa are included. Here also is the report's, Appendix B
