Working with SEH Engineering, SPS Technology undertook the in-situ bridge repair of the existing Grand Duchess Charlotte Bridge (Pont Rouge), which included the addition of a pedestrian walkway. 

Pont Rouge was upgraded from six vehicle lanes to a mixed-use bridge, fulfilling modern day requirements.  The bridge now accommodates four SPS-strengthened vehicle lanes and two newly installed tram lines. By improving the bridge construction, a two-way cycle lane and pedestrian walkways on either side have also been provided on the newly installed SPS panels, totalling over 2,240m² [24,111ft²].
