The A-6 motorway on the Klucz-Kijewo section, almost 8 km long, consists of two roadways with two lanes with a width of 3.5 m and an emergency parking lane with a width of 2.75 m. As part of the investment, 15 engineering structures were rebuilt, i.e.: viaducts in and under the road. The net value of the project amounted to PLN 96 million.
