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 a stats listing, so you can see how many Little Bridges you have found, you can find it here: - Little Bridges Geocaching Series (littlebridgesseries.co.uk). If you would like to add to the series, please go to this site, on the tab Get Involved click number request and fill in the form. To qualify, the bridge must be a foot bridge too small for vehicles, please make sure your title exactly matches “Little Bridges # xxxx then the name” including spaces so it will get picked up and added to stats list.
