At this point you'll see the Whitewater River Masonry Bridge, a single-arch bridge built in 1910. Continue to the single-arch Henry Creek Bridge by backtracking west on 160 to Diamond, 2 miles south on Diamond, then 2½ miles east on 140. Nine more stone bridges can be found throughout the county. A guide is available in El Dorado at the city hall, 220 E. 1st Ave. or with this PDF.
