Caroual Viaduct

Highlight • Bridge

Located on the edge of the seafront in Caroual, the Caroual viaduct is a work of art on the departmental railway line linking Saint-Brieuc to Saint-Briac, built between 1913 and 1916 by the engineer Briochin des Ponts et Roads, Harel de la Noë.
With a total length of 109.25 m, maximum height 17.50 m, useful width 4.22 m, it includes a central arch with a span of 45 m and is made of local pink sandstone masonry and reinforced concrete.
The “little train of the Côtes du Nord” will bring generations of summer visitors to Erquy, from July 11, 1922 to December 31, 1948, the date of its final shutdown.
The Caroual Viaduct was transferred to the municipality by administrative act of September 18, 1959.
