Hidden History #2 - World's Oldest Railway Bridge Mystery Cache

Hidden History #2

World's Oldest Railway Bridge

No history series in the Whitstable area would be complete without a cache based on the former Whitstable to Canterbury 'Crab & Winkle' railway line.

The cache coordinates are for the location of the bridge often given the title 'The World's Oldest Railway Bridge'.  A picture of the bridge, which was demolished around 1970, can be found here.  Another bridge which can also claim this title still stands however, hidden away in the undergrowth, not far from the actual location of this cache.

There's little detail about the line on this page, so you'll have to do a little research of your own before attempting this cache in order to locate the it (all the answers have been taken from the Crab and Winkle Line Trust website).

2. The cycle path which follows parts of the railway line is part of which National Route? Answer = B
3. In which year was the winding pond in Clowes Wood built?  Third digit = C
4. On which day in March 1832 was Whitstable Harbour completed?  Second digit = D
