The investment included works on a nearly 8-kilometre section of the S7 expressway between the border of the Świętokrzyskie and Mazowieckie voivodeships and Skarżysko-Kamienna. It connects the S7 expressway with the former route of national road No. 7, and thus facilitates local traffic in the vicinity of Skarżysko Książęce. The Skarżysko-Kamienna bypass is the last section of the S7 in the Świętokrzyskie Voivodeship connecting Kielce with Warsaw and Kraków. As part of the task, a dual carriageway road with two lanes in each direction, 7.6 km long, was built. Budimex has left a reserve for the construction of the third runway. The connection with the route is possible at two junctions: Skarżysko Kamienna Północ and Skarżysko-Kamienna Zachód. In addition, Budimex has constructed 2 bridges, 6 road viaducts (five along the S7 road and one over the S7), 2 crossings for medium and 5 for small animals, retaining walls made of reinforced soil with a total area of 6400 m2.
