The project is aimed at the construction of the S61 expressway in Łomża Zawest — Stawiski for a long time. 29.35 km. The project consists of 2 sections, implemented as separate works contracts: •Question 4: Łomża West (with knot) — Kolno knot (without knot) for approx. 12.92 km (S61)+ 6.96 km (dk 64-GP) •Task 5: Kolno knot (with knot) — Stawiski node (without knot) for approx. 16.43 km (S61)+ 2.25 km (dk 63-GP) The tasks of the investment are numbered from 4, as the investment was originally prepared as part of a larger project consisting of 6 tasks. The investment is located in the north-eastern part of Poland and runs through the Podlaskie Voivodeship. The planned road is partly followed by a new trail mainly on the section of Łomża West — in. Kolno and partly within the existing section of dk 61. The investment is carried out in the P &B system. The beginning of the construction of the S61 expressway for Task 4 was adopted in km 0 + 014.16 in front of the Łomża West junction. In km 13 + 031.84 = 0 + 000,00 this is the beginning of the Stawisk ring road. On the entire course of the Stawisk bypass, where in km 3+ 395.36 in front of the Stawiski junction the end of the development scope is located, the left road is to be added. On the right road, however, the existing roadway will be rebuilt from km 0+ 000.00 to km 3+ 061.00. Before the Stawiski node there is a connection to task no. 6.
