We were there in the height of summer this year and no bridge then. Looks like there hasn't been a bridge here for a long time. The 1:50 000 doesn't have one marked so we weren't shocked but were surprised to see the remaining supports.
We were a group of bridge engineer's so can't walk past such structures without looking

.
(un)fortunately we draw the line of geeky-ness at taking photographs of such things.
Anyway, abutments are still there, holding down bolts not. Bearing level looks very unlevel, but maybe that was how is was originally built.
Many bridges in remote settings like this are typically designed to not withstand extreme flood events and thus allow them to wash away....
