El Dorado County, California: Bridges of Weber Creek

February 2013 Topo Map of Weber Creek

We've spent several weeks studying the odd assortment of bridges that cross Weber Creek. On the topo map above we can see how this little creek has dug a deep canyon southeast of Placerville (K) (where it was dammed) westward to the South Fork of the American River (shown above Weber Creek) just before Folsom Lake (A).
The bridges crossing Weber Creek include:
B: Lotus Road Bridges, a 1920s era slab bridge and a 1980s era box girder bridge (shown on 2/22).
C: Green Valley Road Bridge, a concrete T girder bridge built in 1926 (shown on 2/21).
D1: The New State Route 50 Bridges, steel stringer bridges built in 1963 (shown from 2/11 to 2/13).
D2: The Old State Route 50 Bridge, a concrete T girder bridge built in 1938 (shown 2/11 to 2/13).
E: Forni Road Bridge, a three span concrete open spandrel arch built in 1914 (shown from 2/8 to 2/10).
F: The Southern Pacific Railroad Viaduct built in 1903 (shown from 2/14 to 2/16).
G: The State Route 49 Bridge, a one span concrete box girder bridge built in 1963 (shown on 2/17).
H: Big Cut Road Bridge a two span concrete T girder bridge built in 1922 (shown on 2/18).
I: Cedar Ravine Road Bridge, a single span concrete slab bridge built in 1930 (shown on 2/19).
J: The Newton Road Bridge, a small concrete slab bridge built in 1929 (shown on 2/20).
That's a lot of bridges for such a tiny creek. The much wider South Fork of the American River north of Weber Creek (that we previously studied) has far fewer bridges, probably because its more expensive to cross.
