To open up the Central Massif, freight trains encountered a difficulty in the Truyère valley. At the time, the piers of bridges could not exceed 65 meters. It is Léon Boyer, born in Florac, thanks to the iron lace bridge made by the Eiffel company on the Douro in Porto, Portugal. The Maria Pia viaduct will serve as a model for the Garabit viaduct. Gustave Eiffel and Léon Boyer built the viaduct in 4 years, despite the septic tanks of the time. It was the largest viaduct in the world at the time.
Men and animals come together to do the work of today's machines. For the transport of materials, we only had animal traction, with teams of 6 to 8 horses.
On the A75 motorway, stop to see this masterpiece of the iron magician!
Léon Boyer also went to Panama to be the general manager of the Panama Canal works by Ferdinand de Lesseps, where French know-how is already at work for the interoceanic canal. He died of yellow fever a few months later!
