If you are unable to visit the bridge yourself, take a look at
this excellent website which will give you a 360 degree view of the bridge. You can also follow the water flow level of the river at this bridge by visiting the Department of Water affairs' website. This link displays only a graph of the water flow levels. To view hourly data, visit this link.
But best still, visit the bridge and claim this cache.
Little is known about the bridge, but in the region of the
current bridge, some 150 000 years ago (during the stone age)
recent discoveries let to the conclusion that a workshop for stone
tools existed in that region, according to the link.
How to locate the cache
1. Measure the length of the bridge.
This given coordinates is the starting location. There are two sement pillars(North and East side) on top of the "pavement" of the bridge. Start there and measure it until you reach similar pilars on the other side of the bridge. (You can also use Google Earth if you want to cheat!) If you start on the North West side and you end at the Free state side, you will be closer to the final cache.
2. Round the length to the nearest 50 meters.
That is: A length of 174 m would result in an answer of 150m. A length of 224m would result in an answer of 200m.
3.The cache is at the following coordinates:S 26° 58.YYY' where YYY = (answer from 2) + 11; E 27° 12.XXX' where XXX = (answer from 2) x 3.064 ;
Happy Caching and protect the Vredefort Dome!
