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.
