S5 expressway (Nowe Marzy – Bydgoszcz – Gniezno – Poznań – Wrocław)

Design-build contract signed 28 April 2020 with Budimex; pl.wikipedia gives 31 months, and the register has contractual completion on 28 May 2023. Includes the Ostróda Zachód junction. The GDDKiA page records permanent traffic organisation from 20 December 2022; pl.wikipedia gives 22 December 2022. This is the only built part of S5 north of Nowe Marzy; Wirwajdy – Nowe Marzy is not built.

Design-build. The 2015 contract with Impresa Pizzarotti (signed 12 October 2015, works from 6 July 2017) was terminated; GDDKiA withdrew from it on 11 June 2019 (pl.wikipedia, after the contractor stopped work in April 2019). The continuation contract went to Budimex (signed 24 April 2020 on the GDDKiA page, 27 April 2020 in the register; works from 5 May 2020). Main carriageway opened on 26 August 2022. The drawn centreline measures 21.05 km, about 10% below the 23.3 km contract length.

Design-build. The 2015 contract with Impresa Pizzarotti (works from 13 July 2017) was terminated; GDDKiA withdrew from it on 11 June 2019 (pl.wikipedia, after the contractor stopped work in April 2019). The continuation contract went to the Kobylarnia – Mirbud consortium (signed 23 April 2020, works from 30 April 2020; tender announced 27 August 2019). pl.wikipedia: Bydgoszcz Północ – Trzeciewiec was passable from June 2022; the GDDKiA page gives 21 October 2022 for the main carriageway and 22 December 2022 for permanent traffic organisation.

Design-build by Intercor and Trakcja (formerly Aleksandrowo – Tryszczyn). Main carriageway opened on 31 December 2019, permanent traffic organisation on 31 December 2020. pl.wikipedia gives 14.1 km for the section.

Design-build (formerly Tryszczyn – Białe Błota) by Polaqua and Dragados. Main carriageway opened on 31 December 2020, permanent traffic organisation on 30 June 2021. pl.wikipedia splits the section into Opławiec – Bydgoszcz Zachód (6.3 km) and Bydgoszcz Zachód – Bydgoszcz Błonie (7.2 km), both opened on 31 December 2020. The second part shares its route with S10, which is not in this dataset, so it is not marked as shared.

Design-build. The 2015 contract with Impresa Pizzarotti (works from 1 September 2017) was terminated; GDDKiA withdrew from it on 11 June 2019 (pl.wikipedia, after the contractor stopped work in April 2019). The continuation contract went to the Kobylarnia – Mirbud consortium (signed 13 March 2020, works from 20 March 2020). Main carriageway opened on 23 December 2021, permanent traffic organisation on 31 August 2022. The recorded 9.7 km runs from Białe Błota to Szubin, both without the junction; the line is drawn between the Bydgoszcz Błonie and Szubin Północ junction nodes and measures 12.74 km, so the two do not agree.

Design-build (formerly Szubin – Jaroszewo) by Trakcja and Intercor. Main carriageway opened on 12 October 2020, permanent traffic organisation on 21 December 2021. pl.wikipedia notes that opening of one carriageway was first planned for the turn of January and February 2020.

Design-build (formerly Jaroszewo – voivodeship border) by the Kobylarnia – Mirbud consortium. The GDDKiA section name ends at the border of Kujawsko-Pomorskie and Wielkopolskie voivodeships, next to the Mieleszyn junction. Main carriageway opened on 23 December 2019, permanent traffic organisation on 9 April 2020.

Built to the traditional design-then-build model (works contract with Budimex and Ferrovial Agroman, signed 3 December 2014; the register lists the works start on the same date, so no construction start is recorded). The GDDKiA page names the section Mielno (with junction) – Gniezno (junction Łubowo); the Mieleszyn junction was formerly called Mielno. Tender announced 14 June 2013 (pl.wikipedia). The page gives 4 May 2017 for the main carriageway and 28 April 2017 for permanent traffic organisation.

First part of the eastern bypass of Poznań (Gniezno – Poznań), traditional model. The GDDKiA page records 2009–2012 as the years of works and 4 June 2012 as the opening, which pl.wikipedia gives for the whole 35 km Gniezno Południe – Poznań Wschód (first passable, with temporary kilometrage). Contractor not named in the sources used. The cut is placed where the line passes the Czachurki village (OSM place node, 0.1 km away); the drawn line measures 14.1 km against 14.9 km on the GDDKiA page.

The Radomicko end is the south end of the Lipno junction (Radomicko village lies next to it; the GDDKiA name excludes the junction). The drawn line measures 20.29 km against 19.14 km. Opened on 9 November 2018.

Stage II of Radomicko – Kaczkowo, traditional model; works contract with Budimex signed 5 May 2016 in the register (6 May 2016 in pl.wikipedia; the register gives the same date as works start, so no construction start is recorded). pl.wikipedia gives a cost of PLN 189.1 million gross, below the PLN 232.65 million contract value of the register.

pl.wikipedia: contract signed 30 July 2010, terminated through the contractor's fault on 21 June 2013, and a new contract to finish the works signed on 21 February 2014. The GDDKiA page gives 29.2 km (plus 8.9 km), works 2009–2014, and 15 September 2014 for permanent traffic organisation; the contractors are not named in the sources used and the page's PLN 1,148 million is an investment value of unclear scope, so no cost is recorded. The drawn line, between the Rydzyna and Korzeńsko junctions, measures 26.22 km.

Task 1 of the three design-build contracts for Korzeńsko – Wrocław (A8, Widawa), km 108+758 to 123+700, 14.942 km. Contract signed 31 July 2014 (the register gives the same date as works start, so no construction start is recorded). Opened on 6 November 2017, about 6 weeks before the deadline (pl.wikipedia). The km 123+700 end is not an OSM node: the boundary is placed by the sourced length of 14.942 km from the Korzeńsko junction. The 4.3 km to the Krościna junction given by pl.wikipedia would put it about 1.6 km further along.

Task 2 of the three design-build contracts for Korzeńsko – Wrocław, Krościna to Marcinowo, 13.8 km. Contract signed 12 September 2014 (the register gives the same date as works start, so no construction start is recorded). The GDDKiA page gives 6 November 2017 for the part up to the Krościna junction (about 4.3 km) and 22 December 2017 for the rest. The km 123+700 end is placed by the sourced length of the previous task; the Marcinowo end is the point of the line nearest to Marcinowo village (OSM place node, 0.4 km away). The drawn line measures 15.75 km against 13.8 km.
