As a member of the Dutch independent LEGO-club "de Bouwsteen" we've got the
oppurtunity from LEGO Benelux to build the "GIBRALTAR LEGO BRIDGE". When we've
got the green light the drawing and counting begins! With help from the TV-documentaire
we made a work-drawing in scale 1 to 20 cm. In that scale the drawing is 1,5 metres wide! (59
inch) In the Brickshelf-folder you can see the drawings we made ("B-Gibraltar-bridge-
sideviews") With help of the first LEGO-designs (see the Brickshelfpictures "C-first-design
frame and C-first-design-traindeck") and the scaled drawing we could decide the sorts and the
numbers of the LEGO parts and make the order-list of ca. 250.000 parts, with a total weight
of 650 kilos!
The Project is inspired on the documentaire 'Engineering the impossible' seen on Discovery
Channel in which the engineers want to span the Gibraltar Street with an enormous bridge of
1 km (40000 inch) high and a total lenght of ca. 14 km (550000"). This should be the highest
and greatest bridge ever build.
The reason to use this bridge as inspiration is that this bridge has a huge span compared to the
altitude, because only 3 main towers can be placed due to the enormous depth of the
Gibraltar Street. With the LEGO bridge the depth isn't a problem, the altitude is. We create a
similar problem: making a span as long as possible with a low altitude in proportion.
The designers solved this problem to combine two classic bridge-designs: the cable-stayed
bridge and the suspension bridge. The main-towers with the revolutional 'diagonals' work as a
cable-stayed bridge; Between the ends of the 'diagonals' the main cable of the suspension part
is attached. De LEGO bridge has in contrast to the real project two in stead of three main
When after a lot of work all the LEGO compartments were ready, the exciting Try-out day
begins: Will the LEGObridge hold it's 12,45 metres long traindeck? In the "Try-out-day
pictures" you will notice that after 8 hours building with 4 people the bridge works! Who
would have thought that? Minimal alterations and improvements were made and the bridge is
displayed on the big LEGO-event in Zwolle, the Netherlands, called LEGOWORLD.
The bridge is shown on national television in three different programs and it's pictures
occured in many papers. What a great project. Enjoy the pictures!

WOW, this is a tremendous project!! I think my wife would definitely cut me off if I came home with that many LEGO and she noticed how empty our bank account was! LOL Very impressive gentleman! Congrats on the recognition!
