In the weekend closure of 19 and March 20 2011, CT deBoer bv skiddid the roadway underpass Baanhoek in Sliedrecht. The 62 meter long bridge deck, where a single railway track runs over, was made 12 meters next to its final position. The formwork supporting girder were also provided by CT deBoer. In a first weekend closure the abutments and foundation slabs were made. After hardening of the concrete the railway deck was then inserted in a weekend, using 6 skidding beams.
