Millau Bridge in France
The Millau bridge or Millau Viaduct That goes across the valley of the river tarn. It is made up of a steel road way and concrete pylons. The entire roadway weighs 40,000 short tons and is 8,070 feet long which makes it one of the largest bridges in the world. It was designed by the french engineer Michel Virlogeux and british architect Norman Foster. It took about four years to build (even though they had wanted to finish it in three years) because weather conditions put it behind schedule.

This bridge's official name is the Liffey Bridge. It was made to replace the ferries that were in terrible condition and was made into a kind of toll bridge but if the citizens of the town decided that they  found the bridge and the toll objectionable they could have it removed. The bridge got the name Ha'Penny because that was what the toll was.

This bridge is above a small creek in Fulton. There wasn't much on this bridge so I'm thinking it's a smaller bridge that not many people have ever seen but it's still interesting.
