The project aims to build the S7 expressway at the section Napierki – Płońsk with a length of 71.21 km. Includes 4 adjacent sections of the S7 road: 1. Napierki – Mława (from 0 + 000.00 to 13 + 967,76) 2. Mława – Strzegowo (from 13 + 967.76 to 35 + 470,85) 3. Strzegowo – Pieńki (from 35 + 470.85 to 57 + 461.63) 4. Pieńki – Płońsk (from 57 + 461.63 to 71 + 213,82). The planned road runs partly along the existing section of national road No 7 and in the new corridor mainly on the eastern side of the existing national road. The investment is implemented in the Design & Build system.
