Nano Challenge: Grafton Bridge Traditional Cache

Designed by engineer R. F. Moore, and its construction supervised by the city's engineer, W. E. Bush,the bridge was built in 1910 and was the third bridge to cross Grafton Gully. The first two bridges (built 1884 & 1905)[citation needed] were pedestrian bridges which ran from the bottom of St Martins Lane to Grafton Road (the current bridge connects Karangahape Road and Grafton Road). These cable-stay bridges were comparatively unstable, and it was said of one that police were stationed on the bridge after rugby matches to ensure rowdy crowds did not cause it to collapse by jumping or stamping on it.

The new bridge was championed by the Mayor Sir Arthur Myers (who advocated for it to be twice as wide as it was eventually built). Even in its narrower form, it was to cost £31,918, resulting in it being called "Myers' Folly" by many at the time, but was also seen to symbolise a commitment to a 'Greater Auckland' as well as state leadership in technology development.

Built of reinforced concrete by the Ferro-Concrete Company of Australasia Ltd, it is believed to have been the biggest arch bridge span of that type existing at that time. It utilises large 'false piers' at each end which give the appearance of strength in the classical masonry style, but are actually not required to be anywhere as massive. In order to dispel doubts about the strength of the still relatively untested type of construction, at the opening in April 1910 two steam rollers were driven across it. This lack of trust had also led to a stipulation in the original construction contract that no progress payments should be made, causing the construction company to go into bankruptcy, with the bridge having to be completed by the city. This also added to the final costs, which were around £33,000. (source wikipedia)

This cache is part of the Auckland Nano Challenge. The caches have a higher, but not unsolvable difficulty level and are mostly placed at high muggle areas. Naturaly, you need to bring your pen, since this cache is of nano size.
The cache is accessible from the pedestrian on the Grafton Bridge. You have to park your car somewhere else, since this is a high traffic area during day and night. Extra stealth is required due to a lot of Muggles. Depending on how tall you are, you might have to stand on your toes to receive the cache.
Please put the cache back to the exact location where it was before
