A little bridge across the Portishead Marina lock.
This bridge is one of two, right next to each other. Periodically, they will open individually to allow watercraft entry and exit to the marina. The cache is not on the bridge itself for this reason. However, it is only a few metres away.
The cache is a simple micro without any real difficulty. Stealth is required, as are pen and tweezers.
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 run by Billiethecat, so you can see how many Little Bridges you have found, you can find it here:- https://littlebridgesseries.wordpress.com/ . 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 # xxxx then the name” including spaces so it will get picked up and added to stats list.
