Rochefort-Martrou Transporter Bridge

Rochefort-Martrou Transporter Bridge, Échillais

Spanning the Charente river between Rochefort and Échillais in the Charente-Maritime department, this bridge looks like a piece of engineering from another century. The Rochefort-Martrou Transporter Bridge is one of the last working transporter bridges in France — instead of a conventional span, it uses a gondola suspended beneath a tall steel frame to carry pedestrians, cyclists and vehicles across the river without ever blocking shipping traffic bound for the ports of Rochefort and Tonnay-Charente.

Where did this bridge come from?

Construction finished between 1898 and 1900, designed by French engineer Ferdinand Arnodin, a specialist in this unusual bridge type. Transporter bridges emerged in the late 19th century as a solution for crossing navigable rivers without a conventional pier-based bridge blocking ship traffic — a tall frame let vessels pass freely underneath, while a cable-suspended gondola carried road traffic from bank to bank. Rochefort, a major shipbuilding town and former naval base founded in the 17th century, needed exactly this kind of solution to avoid restricting vessels heading into its port.

How big is the structure?

The bridge stretches 175.5 metres in length, with its highest point reaching 66.5 metres above the river. A single crossing by gondola takes 75 seconds, not counting the time needed to board and disembark. That is short enough to make the crossing part of everyday life for locals, yet dramatic enough to draw visitors who want to see the bridge in motion.

Why did it stop running, and how did it come back?

The transporter bridge was taken out of service in 1967 in favour of a vertical lift bridge meant to handle growing traffic more efficiently. That replacement was itself demolished in 1991, just months after a new dual-carriageway road bridge, the Martrou viaduct, opened and took over as the main crossing. The transporter bridge survived this period and was fully refurbished by 1994. It had already been listed as a historical monument in 1976, a status that helped protect it from demolition.

Can visitors still cross it today?

Yes — from April through the end of October, the bridge operates and visitors can cross the river on foot, by bicycle or by moped. It is a rare chance to experience 19th-century transport technology in action rather than just admire it from the riverbank. Visiting during the warmer months is essential, since the bridge does not run outside this season.

Frequently Asked Questions

Is the Rochefort-Martrou Transporter Bridge still in use? Yes, it operates seasonally from April to the end of October, carrying pedestrians, cyclists and moped riders between Rochefort and Échillais.

How long does the crossing take? The gondola ride itself lasts 75 seconds, though boarding and disembarking add extra time to the full crossing.

Why was this bridge built instead of a regular one? The transporter design let ships sailing to the ports of Rochefort and Tonnay-Charente pass freely underneath, avoiding the need for a high embankment or a lift bridge that would interrupt road traffic.

Is it the only bridge of its kind in France? Yes, the Rochefort-Martrou bridge is the last operating transporter bridge in the country, making it a unique piece of engineering heritage.
