The ford and the footbridge
In the 19th century, crossing the Frémur estuary was possible by a ford at low tide or by a ferryman at high tide. A submersible wooden footbridge of approximately 25 m was built in 1878 to facilitate movement between the two banks at low tide2.
First bridge
From 1912, the departments of Côtes-du-Nord and Ille-et-Vilaine considered the construction of a viaduct based on the Pointe du Grognet in Lancieux. Its particular objective would be to allow the Le Guildo - Saint-Briac line of the Côtes-du-Nord Railways to cross the Frémur between Lancieux and Saint-Briac3. The first bridge over the Frémur was built in reinforced concrete by Louis Harel de la Noe and was put into service in 1929. Unfortunately, the line was stopped in 1932. The train crossed the bridge for two years and stopped at the end of the bridge. bridge because the line will never be connected to that of Dinard which stopped at la Houle. The bridge will be used as a road bridge. Several arches of the bridge were blown up in August 1944 during the Liberation. The footbridge from the end of the 19th century was then temporarily put back into service2. This bridge is repaired and reopened to traffic.
The Emerald Balcony
The road which passes over the bridge is extended by a cornice road4 which skirts the village to the West. This work of 1,217 m of trenches and cornice was inaugurated in the summer of 1931.
Second bridge
Considered too narrow, the first bridge was destroyed in 1979[secondary source desired]. It was replaced in 1980 by a rectilinear prestressed concrete bridge on a slightly different layout from the first bridge[secondary source desired].
