Vojkovici - The floods in late December and early
January had its impact on structures throughout the Theatre. One
of those structures, the road-bridge in Vojkovici, finally gave
up after having fought and lost against water. But the bridge
had not given up all its strength. It put up quite a fight when
SFOR engineers arrived to tear the rest down.
Hungarian,
German, Spanish, and Romanian engineers powered up with cables
of steel, and muscles of armour. Two German Pioneer-Panzer, a
special winch-bulldozer, and two normal bulldozers and a truck
as anchors gave the SFOR engineers a pull of over 320 tons. But
the bridge, full of its former pride and approximately 360 tons
of concrete and steel, proved to be more demanding than first
expected. After pulling the armoured-concrete rests nearly over
the finish line, the stubborn bridge resisted to a full stop.
First a big shackle gave way to the pressure. Then one of the
36-mm. thick steel wires snapped like a piece of string. The weight
of the bridge so great, that an armoured hook on one Pioneer-Panzer
gave way and had to be replaced.
The
original bridge was built for the Olympic Winter Games in Sarajevo
held 1984. It collapsed the first time in 1995, and was temporary
repaired in 1996 by French IFOR engineers who put a Mabey&Johnson
military bridge on top of the old one. The road was at that time
important to NATO because it worked as an alternative route to
the old HQ in Ilidza.
When the flood came in December, the water forced away the
ground under the pillars in the middle of the river. They fell,
and dragged down both the rests of the old concrete bridge, and
the military bridge on top of it, said Maj. Joseph Gadar,
chief of the operation.
After
dismantling the military bridge, the clue was to pull the rest
of the concrete bridge off the old foundation and into the river,
so concrete breakers could deal with it there.
Only a pull of one and a half metre. No problem, but it
takes time, said Maj. Gadar.
Finally
the bridge gave up, and fell to a rest by the riverbank. The Engineer
Support Unit (ESU) moved in with a concrete-breaker, and broke
away the solid pavement on the old bridge. Then the engineers
used a blowtorch to cut through the steel concrete armour surrounding
the enormous steel frame before it could be moved from the riverbank.
This
is a big task, and it is not a typical task for the soldiers,
said Maj. Gadar. Engineers are more famous for building, not tearing
down bridges.
The concrete is so heavy, and the position in reference
to the river too dangerous to use cranes or heavy breaker equipment,
he said.
Therefore they had to test their strength, and won against the
Vojkovici Bridge.
