The bridge program in steel beam design brings the C-track into the third dimension. With the sturdy structures and the proven pillars 7250 to 7253, ramps, access roads, and overpasses can be built according to the system. The inserted C-tracks are adjustable in length, allowing for individual positioning of the bridges on the layout. The width of the bridges accommodates parallel access roads even within the track spacing of the slim switch geometry of 64.3 mm. Suitable brackets are available for overhead line masts and light signals in the bridge area.
