AERIAL LIFT BRIDGE

This steel-framed ferry bridge was inaugurated in 1905. Designed after the Rouen bridge, the first bridge, with its retractable deck system, served for twenty years. In 1925, it was realized that ship traffic was too heavy and the removal of the deck too long. The engineers invented a new system: the deck is now raised by a system of pulleys that raise the deck above the boats. It goes up and down about 26 times a day, and its rise and fall time is two and a half minutes.
