The project aims to build the S7 expressway on the Nidzica-Napierki section. The beginning of the construction of the S7 expressway is located in km 25+ 730 (new design) and is related to the end of the construction of the previous section of S7 Olsztynek – Nidzica. The projected road runs in a new corridor in the largest distance from the town of Nidzica by approx. 1.4 km from the existing route to the west. The route has limited availability, which will be carried out by 4 knots. The end of construction of the S7 expressway is located in the area of Mazowieckie Voivodeship in km 47+ 793.18, where the connection section within the 0.28 km long DK7 takes place. The project is implemented in a traditional system divided into 2 tasks: It’s the ass. 1: Nidzica bypass – from Nidzica junction – North (with node) to Nidzica junction – South (with knot); It’s the ass. 2: From Nidzica-South (without no knot) to vengeance. It’s a napierki. Administratively, the investment is located in the northern part of Poland, in the Warmia-Mazury Voivodeship (in its south part) and Mazowieckie (north part). The course of the planned S7 begins to the north of the border of the town and commune of Nidzica, from where it runs south, crossing the area of Janowiec Kościelny commune, ending its course in Wieczfnia Kościelna commune already in the Mazowieckie Voivodeship. The main part of the project is the construction of the S7 expressway on the pc. Nidzica – Napierki, located in the TEN-T core network with a total length of 22.06 km. is complemented by a transitional section (the transitional section was built on the parameters of the expressway. However, until the construction of the S7 on the Napierki-Płońsk section, it will not be marked as an expressway, acting as a link between the existing single-way cross-section with the newly built two-way section) to the existing 0.28 km long road.
