The European Investment Bank Institute and Europa Nostra, the leading heritage organisation in Europe, have published a technical and financial report on the rehabilitation of the Colbert Swing Bridge in Dieppe, France, listed among The 7 Most Endangered heritage sites in Europe in 2016. The European experts recommended that the Colbert Bridge is nominated for National Monument status with the utmost urgency. The bridge was classified in 2020.

Contemporaneous with the Eiffel Tower and using the same building techniques and materials (puddled iron), the Colbert Bridge is the last large swing bridge still operating in Europe with its original hydraulic mechanism. It has operated continuously for nearly 130 years with a very high degree of reliability. The rehabilitation project of the 1889 bridge would require 4.5 to 5 million euros.

The EIB Institute facilitates the transfer of know-how and experience between different partners and countries in the heritage conservation field. It cooperates with Europa Nostra to identify those under acute danger of neglect or destruction. This innovative cooperation mixes the cultural expertise and lobbying work of Europa Nostra with the technical appraisal and rescue planning skills of the EIB and of the Council of Europe Development Bank. The EIB/CEB experts carry out on-site missions and produce technical reports on the viability and phasing of the project recuperation as well as on the funding options.
