The published coordinates take you to the Diamond Jubilee Footbridge across the Kennet and Avon Canal. This is not the final location of the cache.
You need to be on the footbridge and not the road bridge in order to find the plaque that will give you the numbers required in order to work out the final location.
Focus on the last line of text.
A = number of words.
B = number of letters in the 4th word.
C = number of letters in the 6th word.
D = number of letters in the 1st word.
Now use the values of A, B, C and D in the following formula:
N51 24.ABC
W001 30.D(D-B)D
The cache is a 50ml tube and the final location is along the tow path.
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 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 Damian’s list.
