Some important notes
The cache is not in the published coords (these are for the
center of bridge). Read the description to find the cache location,
but first read the safety guidelines:
- The cache area has high traffic of all kind of vehicles,
including the light rail. Use the bridge and crosswalks to cross
the roads or rails.
- Don't walk on the rails. Cross the bridge only on the
pedestrian path.
- Don't touch, climb or enter any electrical infrastructure.
- Don't try to climb anything.
- Everything you need on the way to the cache can be seen and
searched from safe places. If you think you have to stand on the
road, on the rails, climb something or look inside something
electrical - you wrong, check again.
The chords Bridge
The Jerusalem Chords Bridge is a cantilever spar cable-stayed
bridge at the entrance to Jerusalem, Israel. The bridge will be
used by trams running from outlying Jerusalem neighborhoods to the
center of the city. Incorporated in the structure is a glass-sided
pedestrian bridge enabling pedestrians to cross from Kiryat Moshe
to the Jerusalem Central Bus Station.
Designed by the Spanish architect and engineer Santiago Calatrava,
its construction began in 2005 at a cost of 220 million NIS. The
bridge consists of a single pylon counterbalancing a 160 metre span
with lengths of cables, making a dramatic architectural statement.
A striking feature of the bridge is a single 118-meter high mast
supported by steel cables, making it the tallest structure in
Jerusalem at the time of its completion. Some say the bridge
symbolizes David's harp. Others interpret the looming pylon as the
bust of a long-necked bird, a human arm or an arrow caught in a
bow.
More information in Wikipedia.
Interesting facts about the bridge:
- The chords go from the pole top down to the bridge in 3 groups.
Two groups go to each side of the bridge and a third one, goes in
the center to the pole base. The largest group has exactly
A chords, while the smallest group has just
B chords.
- The floor of the pedestrian bridge is made of limestone, steel
and also C glass tiles.
- The side is also made of glass. If you come from south (Kiryat
Moshe), you can count on the side, D pieces of
glass wall, above stone floor, until you arrive the glass
floor.
- When you walk on the pedestrian bridge, you can see the
E T shaped electric poles, which are used by the
light rail.
- When you are on the highest point on the pedestrian bridge,
look down. You will see a row of stone benches. Go down and count
the number of legs on the benches (both forward and backward legs)
F.
- Now look around (on the same side of the road) and you will
find another row of objects with the same type of legs. On these
objects, you can count G legs.
- Look again on the stone benches. The left one points by exact
straight line from the top of the bench to some
object.
- If the object is an electric pole,
units='mm'
- If the object is a sign,
units='cm'
- If the object is a tree,
units='inches'
- If the object is a pipe,
units='feet'
- If the object is a fire hydrant,
units='m'
- If the object is an unpublished cache, with
brand new GPSr as FTF prize, units='km'
- If it is a GPS satellite,
units='light-years'.
- In case of emergency, call Sergei. To do so, you have to dial
exactly J times the digit '1'.
- Oops, I almost forgot to warn you. If you arrive from Tel Aviv
to Jerusalem by car, and want to turn right under the bridge to
Shderot Herzl, it is a good idea to check that your car is not
higher then H meter.
- Now, go to the point, where the central group of chords
connects to the base of the bridge. Under this point you will find
the start of a straight row with I lamps which
illuminate the bridge.
Find the cache
Now, after you know well the bridge, you probably want to find
the cache. First calculate:
LMN= last 3 digits of C+D-G-I
PQR= last 3 digits of E*F
X = A+H-B*J
Go to N 31°??.LMN E 035°??.PQR (It's less than
500m walk). You are near the start of something. Find its other
end. When you arrive the other end, the cache is X
units to your right.
This cache is dedicated to
Irisvo, who is known for her quality caches, many of them near
bridges of all kinds, reflecting her special interest in bridges.
One of her caches, the 3D
cache, is less than 300m from here, near another nice
bridge.
Thanks to Jdevor for the cache container.
