1. The streets of Novosibirsk are too narrow for heavy traffic. What can solve the problem of two-tiered roadways – bridges or tunnels? Mind the geological conditions and radon emissions.
2. New Zealand is an island country and it is a seismically active area. What is the best transport connection for such regions?
3. The territories beyond the Arctic Circle attract business attention because they are very rich in mineral recourses. Soon they will be populated and need some Railway and Motorway ES. What kinds are preferable for permafrost?

Radio Tech presenter Tom Burns interviews engineer Galal Hamdy.
Tom: What project are you working on now?
Galal: We’re designing the world’s longest road bridge. Look at its small-scale model.
Tom: It’s really beautiful and looks very light. And what’s the bridge made of?
Galal: Yes, it looks light because it is light. It uses the minimum amount of material. But it is very strong.
Tom: Where will it be?
Galal: Between Morocco and Spain. It’ll connect Europe with Africa.
Tom: What are the specifications of the bridge?
Galal: Its total length will be almost 15 km long. In our design, the bridge will have two spans. Each span will be 4, 800 m long.
Tom: That’s a very long span. How will that be possible?
Galal: The bridge will have three steel pylons on concrete piers. The pylons will be 1, 000 m high. The deck will be very light and strong. It’ll be made of fiberglass.
Tom: How wide will the road deck be?
Galal: It’ll be 32 metres wide. It’ll have four lanes of traffic. The cables are in fact made of steel and the piers, of course, are made of reinforced concrete.
Tom: Many engineers think you won’t be able to build this bridge.
Galal: I don’t agree. I think we’ll complete it around 2030.
