The most spectacular phase of the installation of the new bridge over the railway tracks between Colmar-Berg and Schieren began on Saturday morning.
Moving a 72-metre bridge weighing 700 tonnes is a technical feat. Pulling it off required a huge crane, of which there are only three in Europe.
The old bridge, which was built in 1960, was one of the most vulnerable structures under the Bridges and Roads Authority's management.
Despite multiple strengthening efforts aimed at extending the structure's life, it was ultimately necessary to replace it.
The construction of this new bridge began a year ago, and its assembly on site started in September 2022. On Saturday morning, crowds gathered to witness the most spectacular phase of construction.
The N7 and the CR123 are closed to traffic in both directions from Monday 30 January until the evening of Friday 10 February.
