This is Ling Gill Bridge. To the right the Pennine Way heads down to Horton in Ribblesdale, to the left it rises to the open fells of Camm
The inscription is a bit awkward to make out due to the habit of allowing words to flow from one line to the next (as in REPAIR-ED and W-EST) and the backward N, and the last digit of the year isn't quite clear, but is otherwise legible:

ANNO 176? 
THIS BRIDGE 
WAS REPAIR
ED AT THE 
CHARGE OF 
THE WHOLE W
EST RIDEING

Camm High Road is so called because it runs along the tops of the fells. Don't expect to find the local shops here! The flat topped hill is Ingleborough, one of the so-called three peaks, though none of them is a peak.
Ingleborough again below, with the Ribblehead viaduct on the right. The party on the left is on the Pennine Way heading down to Ling Gill Bridge. The Dales Way goes towards Ribblehead.
