Die Murbrücke – Ein länderübergreifender Cache

This is a quick and easy cache which can be done within about 15 minutes. It can be easily found during a break of a trip by bike from/to Radkersburg and Mureck next to the river Mur.
If you decide to do it by car feel free to drive right to the bridge but it would be nice to park your car as soon as you leave the concrete way.
The coordinates in the header section (N 46° 42.830‘ – E 15° 53.585‘) can be found in the middle of the bridge.
Detailed information about the bikeways can be found at the tourist information centres in e.g. Bad Radkersburg or Mureck. Very detailed maps of the ways are sold. The bridge was opened in 2007 and connects bikeways of Austria and Slovenia.

Stage 1
There is a big information chart next to the bridge in Austria. It informs you about e.g. the companies which built the bridge. The chart is divided into several rectangles. In one of these rectangles a picture of the European Flag can be found. In this special rectangle they talk about the costs and the date of the opening of the bridge. Count the “E”s – small and capital ones – to get the number for the variable A.

Stage2
Walk over the bridge and look for the same information chart – But this time it is written in Slovenian. Check the rectangular, which has an EU flag in it, for the “E”s again. Keep in mind to look for the small and capital ones. This is the number for variable B.

Cache
Now you have to do some maths to find the cache. It is not that difficult and can be done without any help.
X = (A – 1) * 100 + (B * 4)
Y = (A * 40) + {(B * 4) – (2*checksum A + 2*checksum B)}

N 46° 42.X‘
E 15° 53.Y‘

I hope you had fun looking for the cache.

P.S.: To recover from biking you can take a walk in the refreshing water of the river Mur
