Project reminder
Listed as a Historic Monument in 2020 following a strong citizen mobilization and the commitment of communities, the Colbert Bridge is currently undergoing a complete restoration. Its structure, consisting of a mixture of original puddled iron and post-war steel, is very damaged. The current operation consists in the renovation of its pavement and widening of its sidewalks so that it is accessible to people with reduced mobility. Works on civil engineering are also planned: resumption of the circular paving of the area of erasure of the bridge, restoration of the stairs, dock abutments and capping... as well as a restoration of the cab and a facelift of the machinery building.

The move of the bridge, from its usual place to its place of restoration (at the Cours de Dakar), took place from 8 to 10 February 2024, under the admiring gaze of the inhabitants and the press. Colossal resources deployed, at the height of this fragile and imposing building.
Preparatory work

Before any transfer operation, many preparations were made:
- Actuator operation at 3m above its rotation area (before any displacement, it is necessary to ensure the weighing of the supporting reactions and the reaction of the bridge deck. It results in the installation of cylinders equipped with pressure sensors associated with displacement sensors).
- Installation of a metal beam of 21 tons and 17m long
- Bridge Mount: 4 mooring cables, 11 pumps to adjust altimetry before moving
- Trailer Installation
Displacement
The transfer operation of the Pont Colbert was then launched. It required a very precise engineering based on the use of barges to support and move (installation of ramps and transport of the bridge from its usual place in the Cours de Dakar).
