I'm calling this cache “Little London Bridge?“ because the road bridge nearby is called London Bridge. The cache is NOT on the road bridge, but near a small foot bridge to the north. To see this in OS maps, click here, or go down underneath the hint to find online maps, and click Streetmap.co.uk.
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 here 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.
