Differentiated road construction costs

In the context of the variability of road construction costs in Europe, the prices of 24 contracts for sections of motorways in Poland, concluded in 2016 by the General Directorate for National Roads and Motorways, were analysed. According to the proposed method of calculation, taking into account the fact that road prices in tunnels were several times higher than in other sections, the unit cost of the road in a tunnel (between Naprawa and Skomielna Biała) was assessed, compared to the road in a tunnel in Slovenia. Based on the study of the values of standard deviations and coefficients of variation, it can be stated that there is a small price differentiation in S-class roads on flat and corrugated areas, and very large price differentials on the roads that bypass cities and in mountainous terrain.
