This is yet another Little Bridge discovered by my wife on her various travels around the county. This time she was visiting Langford Lakes for the first time last summer and it is now an area we both visit frequently to unwind and watch nature from the warmth of the various hides on the site. Thoroughly recommended, so why don't you give it a try?
Visit the bridge to gather the information and work out the final location a short walk away.
Count the number of deck boards on the bridge = A B
Count the number of benches visible from the bridge = C
Cache can be found at N51 07.(AxC) C (B+1) W001 56.(AxC) (C-2) ((A+B+C)-1)

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. There is now a stats listing so you can see how many Little Bridges you have found, you can find a link to it on the Little Bridges Face Book group. 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 stats list.
