The project aims at the construction of the Inowrocław bypass along national road No 15 and national road No 25 (DK15 and DK25) and the Brodnica ring road within national road 15 (DK 15). The length of the Brodnica ring road is 1.48 km, and there is a cross-section along the whole section with a dividing strip in the intersection area. The Inowrocław bypass, with a length of 22.97 km, will have a two-way cross-section with two lanes and a dividing lane. The planned sections of the Inowrocław and Brodnica ring roads are located in the northern part of Poland and run entirely through the Kujawsko-Pomeranian Voivodeship. The construction of these sections will allow transit traffic outside the city centre, thereby increasing the level of safety of road users and will affect the smoother and safer functioning of the road system.
