📋 Tender Overview
In 2020 we made almost 140 km of new roads available for traffic and along with their construction many smaller or larger bridges flyovers and culverts were created. Last year we built renovated or rebuilt 43 bridges on the existing national road network. There are 96 tasks in progress including the construction of new roads with a total length of over 1225.2 km. The renovation of 40 old crossings and the construction of 55 new ones are also underway.The largest bridge in Warsaw During the construction of the Southern Bypass of Warsaw the eleventh bridge in Warsaw the ninth road bridge and the second one on the board of the General Directorate for National Roads and Motorways was built along the S2 expressway. It is also the longest bridge in the capital and the largest of its kind completed last year in the whole country. The new crossing consists of two independent structures with a total length of nearly 1506 m each. The bridge over the Vistula river is almost 534 m long and the two flyovers over the floodplain are almost 349 m on the Wilanw side and approx. 629 m on the Wawer side respectively. Pedestrians and cyclists can use the footpath and bike path on both sides of the bridge. There are five supports in the river current two of which are shared with the flyovers. 320 piles with a diameter of up to 1.5 m were drilled for the foundations of the bridge so-called large-diameter piles DN 1500. Some of them even to a depth of 27 meters below the bottom of the Vistula River to stabilize the ground. In the floodplain part of the bridge on the Wilanw and Wawer sides prefabricated reinforced concrete piles with a total length of about 25.7 km were used to build the foundations. Reinforcing steel for the bridge itself which was delivered via over 320 truck courses is a total of approx. 10000 tons. Concrete was delivered with a total of 12000 courses of concrete mixers. The construction cost of the entire S2 section from the Warszawa Wilanw junction to the Wa Miedzeszyski junction is approximately PLN 758 million. The cost of building a new bridge over the Vistula in the amount of approximately PLN 190 million accounted for a quarter of the value of the entire contract. The entire cross-section of engineering structures During the construction of new road sections many engineering structures are built in addition to bridges flyovers and culverts. Some of them also function as animal passages. During the construction of the S17 between the Lubelska junction and the end of the Kobiel bypass next to the characteristic old bridge over the wider a new one was built consisting of two separate structures. On the other hand on the Wacz bypass along the S10 expressway two flyovers were built over the depression. The longer of them with 13 spans made using the longitudinal slide-on method is 764 m long. Shorter with five spans it is 278 m long. On the investments currently in progress among others the bridge over the San along the S19 expressway approx. 393 m long the bridge over the Wkra near Strzegowo along the future S7. A new bridge over the Dunajec River in Kurw along DK75 is also under construction. Its length will be 602 m and the construction cost is nearly PLN 190 million. We are renovating the existing crossings Last year we completed the renovation of 27 bridges with a total length of approximately 2.6 km and the value of works of nearly PLN 86 million. We have built 16 bridges with a total length of 636 m and the value of the works is almost PLN 159 million. Depending on the technical condition of the building we carry out renovation erect a new bridge in place of the old one or replace it with a culvert. For example in the place of the old bridge on DK79 in Andruszkowice a new bridge was built and in Stporkw on DK42 a huge culvert both structures in witokrzyskie Voivodeship. bridge over the San river in Radymno along DK94. In 2021 40 bridges will be renovated with a total length of approx. 7.8 km and the value of works close to PLN 181 million. In cinawa a historic steel bridge on the Odra River along DK36 route approx. 350 m long will be renovated. Currently supports are under construction for a temporary bridge to which traffic will be transferred for the time of renovation. The renovated bridge will be put into use in 2022. There will be 55 bridges under construction with a total length of nearly 2 km with a total cost of slightly around PLN 609.4 million. We will also build 21 culverts worth nearly PLN 32 million. We secure the gaps between the objects In accordance with the applicable regulations engineering structures are equipped with higher than usual barriers to prevent the vehicle from driving over the edge of the facility and preventing a person from falling from a height. We went a step further and secure the space between the bridge structures along which the carriageways of one route run. After the inventory on the national road network we identified a total of 1537 clearances with a width of min. 10 cm and a total length of 104.6 km. In total we have installed several thousand signs warning against the possibility of falling from a height. In places where there is no lighting on the route and the ground clearance is a risk of falling we have installed additional protection. Depending on the type of object the type of protection is selected an openwork plate a mesh made of plastic or wire. Security features appeared among others on the Zakopane flyovers on the S7 and on other structures in Maopolskie on A1 in the province. Kujawsko-Pomorskie on the facilities within the S5 in the province. Greater Poland and the longest facilities on A6 S3 and S10 in the province. West Pomeranian Voivodeship.
