This is a quick cache and dash, as parking is available in a "passing" space a few yards away. You are looking for a micro sized screw top container.
Not sure how I missed this Little Bridge when I placed my nearby cache (GC87N9Y), but although this particular Bridge isn't as extravagant it still warrants a cache in my humble opinion.
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. A list of cachers who have 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 the list.
