This is a Little Bridges dash'n cache. The bridge co-ordinate is N51 26.791 W002 28.503 (which could easily be missed), because it has no handrails. It crosses over the small stream and constributes to part of the path-way.
The cache is hidden close by, in view of the bridge, at the above co-ordinate.
The Little Bridges series was started by Stanthews in 2009 to highlight small footbridges in remote parts of Wiltshire. Since then the series has been expanded by others all over the country and starting to spread fast, Damian from Winter Foxes has created and updates a list of cachers who has found 10 or more little bridges and can be found here, if you would like to add to the series, please contact Stan on stanthews@aol.com and he will give you a number for your bridge, to qualify, the bridge must be a foot bridge too small for vehicles, please make sure your title exactly matches “Little Bridges # xx then name” including spaces so it will get picked up and added to Damian’s list.
