LANDBRIDGE
Above the roundabout you will find the UKs first Land Bridge. What is it for I hear you ask? Well, apart from providing access to the nearby National Trust property from Lamberhurst, it's primary purpose is to allow wildlife safe passage from one side of the busy dual carriageway below to the other. Mice, voles, foxes and all manner of creatures use this bridge simply to cross the road. It connects populations of mammals which were effectively separated when the Lamberhurst bypass was built.
To locate the cache, please answer the following questions:
What is the name of the National Trust property served by the bridge (num of letters per word)? = AB
Which A Road does the Land Bridge cross over? = CD
How many millions of pounds did it cost to build the Lamberhurst Bypass? = EF
The cache can be found at:
N51 05.(B-C)(A-C)(A-D)
E000 23.(F-E)(D+E)(E+F)
The cache is NOT on any of the roads, your feet will not be on tarmac at the GZ. Please be very careful if you choose to cross the road and please use the crossing islands provided.
Safe parking is available to the west of the roundabout by means of a pull in on the right-hand side of the road as you exit the roundabout towards Lamberhurst.
