The Balclutha Road Bridge, is one of the best-known road bridges in the S. Island. The bridge is often simply known as "The Clutha Bridge", despite there being numerous bridges across the Clutha River. The bowstring bridge (designed by W. L. Newnham) is meant to be earthquake and flood resistant, safeguarding it against the two most common natural disasters to occur in the region. For more details on the bridge, you can find information panels at GC9G6GG, which can be reached without crossing live traffic, it also has some good free parking spaces (parking WP provided).
When you stand at the posted co-ordinates you can see a couple of signs without having to leave the footpath, note you can reach the cache from this location without having to cross any fences or live lanes of traffic - use the trailhead marker from the cattle grates where you are to reach the cache location;
At the top of the grey arch is a warning height sign for traffic (black on yellow) the numbers are A.BC
Across the road from where you stand you can see two signs on the white concrete wall (do not need to step off path - you can read it from this side of the road) note the four digit number for the bridge (black on white sign next to yellow and black bridge name) DEFG
From the posted co-ordinates (S46° 14.198' E169° 44.654') project the co-ordinates;
a distance of STU meters at a bearing (angle) of XYZ degrees.
S= B - E
T= E - D
U= A
X= F - C
Y= G
Z= D
You will need to do a projection from these co-ordinates. There are a number of free apps and websites you can use (search project co-ordinates) to help you complete this. There should be good phone signal out in this area to get online if you have not already downloaded any apps before heading out this way.
Please note whilst some caches have pens placed in them, all cachers should bring their own. Photo logs are not acceptable substitutes and these logs will be deleted.
