This is a photo postcard of the Kaweah River, bridge and the River Inn (Three Rivers, CA).

It's post-marked June 1911, which is just a few of months before the River Inn burned down.

Note: Apparently this print was made with the negative slightly askew.

The following two photographs came from an old album, dated 1912.

The upper photo was taken in Richgrove, CA. The lower pic states that it is at the Kaweah River:

I would guess that they're on the railway bridge that crossed the Kaweah River in the Woodlake/Lemon Cove area.    Note that the power-lines in the background are set up for the Visalia Electric Railroad.

(Update, 10/5/12) The Tulare County Public Library's online digital collection appears to have a color photo of this same bridge, taken at a much later date, e.g.  After they took down the over-head lines for the electric railroad.   Their picture is entitled "Visalia Electric Railroad Bridge Over Kaweah River".
