Question

[P - TV presenter: E = Engineer
P: Yes, the total height of the Millau road bridge
is 336.4 metres above the river Tarn. Now I'm
talking to the chief engineer of the bridge.
So, can I check with you? Three hundred
and thirty-six point four is the total height
from the top of the pylons to the river, is that
right?
E: Yes, that's right. That's the total height. The
road deck itself is 246 metres above the river.
Then the pylons, or towers, rise another 90
metres above the deck.
P: I see. And how wide is the river valley at the
bridge?
E: Well, the valley is almost 2.5 kilometres wide.
In fact, the bridge is 2460 metres long, or 2.46
kilometres.
P: And how long are the spans?
E: They have different lengths. The bridge has
two outer spans and six inner spans. The two
outer spans are 204 metres long, and the six
inner spans are 342 metres long.
P: How wide is the road deck?
E: It's 32 metres wide. It has four lanes of traffic.
P: And what's the bridge made of? It's really
beautiful and it looks very light.
E: Yes, it looks light because it is light. It uses
the minimum material. But it's also very
strong. The cables and the road deck are in
fact made of steel. The seven piers, of course,
are made of reinforced concrete.​
