There is a place to pull off the road close to the cache,room enough for one vehicle on between guide rail & utility pole EAST side of bridge.
This should be a fairly easy one to find, it is just a short walk from where you can park. It ia a small waterproof container containing a log book & pen, might be a good idea to have a pen incase pen is missing.Some room for small items, if you take one just replace it with another one.
