Luxembourg Ville

The project to renovate and widen the Grand Duchess Charlotte Bridge carried out by TRALUX is part of an overarching program to build a new tramway line linking Findel airport and the southern section of the city of Luxembourg.

The bridge renovation and widening project participates in the LuxTram project by including a two-lane tramway line in the deck configuration. The new layout plans therefore feature two lanes of vehicle traffic in both directions, a two way double-lane tramway line on the north side, and sidewalks on the outermost edges of the bridge, widened for more comfortable passage of both pedestrians and cyclists.
