The Trebnje viaduct, which connects the primary road with the town of Trebnje, spans the Temenica river and two railway tracks. The sleek, semi-integral structure, with the total length of 180 m, is continuous over seven spans with a prestressed RC slab of superstructure. Similarly as in the next, the Trebnje overpass, the middle supports have an interesting funnel shape.
The overpass and viaduct, characterised by sleek superstructures and uniform elegant supports, subtly span the shallow terrace below Trebnje.
