Calaveras County, California Bridges: State Route 12 Bridge across Haupt Creek

April 2013 (38.21167 Degrees, -120.76361 Degrees) SR 12 Bridge

Just south of yesterday's Haupt Creek Bridge is something a little different, a single span prestressed concrete box girder bridge built in 1993. The State Route 12 Bridge across Haupt Creek (30 0006) is 107 ft long, 55.4 ft wide, and on a 13 degree skew.

Unlike wet Youngs Creek, Haupt Creek apparently is dry for much of the year. The bridge has sloping exterior girders, end-diaphragm abutments, and a solid New Jersey type barrier. The bridge carries 5800 vehicles a day and has a sufficiency rating of 99.5.

Calaveras County, California Bridges: Double Springs Road Bridge across Haupt Creek

April 2013 (38.21500 Degrees, -120.76194 Degrees) Double Springs Road Bridge

A third, almost identical bridge as we continue east from Lime Creek Road to Double Springs Road just north of the intersection of SR 12 and SR 26. This bridge also has fencing on the upstream end for some reason. All three bridges are county bridges built in the 1910s, probably designed by the same engineer. They're all two span T girder bridges with end-diaphragm abutments, wingwalls, and a center pier wall.

The concrete has a little color, maybe beige. The Double Springs Road Bridge across Haupt Creek (30C0047) is 45 ft long, 23 ft wide, and built in 1917. I don't know why, but they're not eligible for registry as historical places. Maybe they're considered too plain, but like a nice piece of Shaker furniture I think they're perfect.

Calaveras County, California Bridges: Lime Creek Road Bridge across Youngs Creek

April 2013 (38.19278 Degrees, -120.80583 Degrees) Lime Creek Road Bridge

Continuing east on Lime Creek Road we come to another (almost identical) second bridge across Young's Creek. The Creek meanders to the north and then comes back across Lime Creek Road.

The second Lime Creek Road Bridge (30C0019) was built in 1917 (two years later) and it's another two span reinforced concrete T girder bridge. It is 47 ft long and 23 ft wide. It's in good condition, carries 100 vehicles a day, and has a sufficiency rating of 71.5. The strange thing is that the substructure of a bridge is just south of the current bridge. Perhaps they changed the alignment of the road or the previous bridge was washed out by a flood?
