Rochefort-Martrou Transporter Bridge is a transporter bridge built between 1898 and 1900 . It is located in Rochefort, Charente-Maritime, Poitou-Charentes, France. Crossing the Charente River, it has a maximum height of 66.5 metres (218 ft) and a total length of 175.5 metres (576 ft). It is a technical invention accomplished by a French engineer : Ferdinand Arnodin. It was abandoned in 1967 in favour of a vertical lift bridge, which was in in turn demolished in 1991 a few months after the opening of a new dual-carriageway road bridge, the Martrou viaduct. However, the transporter bridge was refurbished by 1994 and is now a historical monument (1976).
