A2 motorway (Świecko – Poznań – Łódź – Warszawa – Siedlce – Biała Podlaska – Kukuryki)

Built by the concessionaire Autostrada Wielkopolska II S.A. as a rebuild of the existing DK2 (km 3+375 to 20+450 on the concession chainage, 17.075 km). The pl.wikipedia table gives 18.7 km and the opening as 30 September 2011; the 3.9 km from the border to the Świecko junction is signposted DK2 and is not drawn. Free of charge.

Concession section of Autostrada Wielkopolska II S.A. (km 20+450 to 107+900, 87.45 km). The pl.wikipedia table gives 84.4 km. Toll from 20 May 2012. The agreement signed on 29 August 2008 planned the start for spring 2009 and the end for 2012; the whole Świecko – Nowy Tomyśl opened almost six months before that deadline. No dated construction start is recorded.

Concession section of Autostrada Wielkopolska S.A., which is responsible for A2 Nowy Tomyśl – Konin (149 km). pl.wikipedia gives 50.4 km and 27 October 2004; toll collection began on 3 November 2004, and the part between Poznań Zachód and Poznań Komorniki is free. The table at the top of the article names this section as ending at Poznań Zachód.

Southern bypass of Poznań, free of charge, shared with S5 and S11 on part of its length. The construction history on pl.wikipedia gives 12 September 2003 and 13.3 km; the table of existing sections gives 13 September 2003 for the longer Poznań Zachód – Poznań Wschód stretch (26.1 km).

Opened on 27 November 2003 (pl.wikipedia, 37.5 km); tolled between Poznań Wschód and Września.

Opened on 9 October 1985 (pl.wikipedia, 34.2 km), modernised in 2002 and tolled from 20 December 2002. The drawn length is 35.25 km.

Opened on 10 November 1988 (pl.wikipedia, 13.8 km) and modernised in 2002. Free of charge.

Built by GDDKiA from 28 July 2004; due in November 2005 and opened eight months late, as the longest motorway section opened at one time in Poland. Free for vehicles under 3.5 t from 1 July 2023 (toll only above that mass). Contractors are not named in the sources read.

Stryków bypass, opened on 22 December 2008 together with a 3 km slip road to one carriageway of the A1 (pl.wikipedia). Three lanes, free of charge. The drawn centreline between the two junction nodes is 3.43 km, longer than the recorded 1.7 km.

Contract section A (29.2 km, Łowicz junction) and the western part of section B (Skierniewice junction). Contracts signed on 28 September 2009 with the works start marked on 14 July 2010; section A went to a consortium led by China Overseas Engineering Group (COVEC), terminated on 13 June 2011 and completed under a contract of 28 July 2011 with Eurovia / Warbud for about PLN 989 million (VAT basis not stated). Section B (17.0 km) went to Mostostal Warszawa / Acciona Infraestructuras / Polimex Mostostal; about 3.8 km of it opened here. Opened to traffic on 3 June 2012; the surface course was then laid, with the northern carriageway reopened on 5 September and the southern on 15 October 2012. Length 32 km from the pl.wikipedia table of sections (the construction history says 33 km). Original COVEC contract value not found.

Contract section C (20.0 km, Wiskitki junction) plus the rest of section B and part of D (Strabag / Mota-Engil). The COVEC-led consortium was terminated on 13 June 2011 (effective 27 June) and section C was completed by DSS / Bögl a Krýsl under the contract of 1 August 2011 (PLN 756.05 million, VAT basis not stated; covers section C only, so it is not recorded as the lot contract value). Opened to traffic on 6 June 2012 with finishing works on the Wiskitki junction continuing to October 2012. Length 41.4 km from the pl.wikipedia table of sections (the construction history says 46 km).

Contract sections D (17.6 km, Strabag / Mota-Engil) and E (7.1 km, Budimex-Dromex / Ferrovial Agroman), without the part of D west of Grodzisk that opened with section C. Pruszków – Konotopa (4.8 km) opened on 23 May 2012 together with 2 km of the S8 to Warszawa Zachodnia; Grodzisk Mazowiecki – Pruszków (12.6 km) opened on 27 May 2012. Length is 12.6 + 4.8 km from the pl.wikipedia table of sections. The OSM ways tagged A2 stop before the Konotopa interchange, so the drawn line is about 15.9 km. The Konotopa – Lubelska gap is carried by S2 and S8.

Design-build contract with Polaqua signed in July 2017 (25 July per pl.wikipedia) for two sections, Lubelska – Halinów (5.6 km) and Halinów – start of the Mińsk Mazowiecki bypass (9.2 km). GDDKiA gives the total investment as almost PLN 755 million including documentation, land and archaeology, of which works about PLN 538 million. Opened on 14 August 2020 (over 15 km). Drawn length is 13.96 km, 7% under the recorded 15 km; the start is the first A2 way after the S17 junction, and the cut at 9.19 km beyond Halinów is by recorded section length.

First eastern section, with junctions Arynów, Lotnisko and Ryczołek. Works started officially on 24 August 2009 and the bypass was opened on 29 August 2012. pl.wikipedia gives the construction cost as PLN 567.4 million and the project total as PLN 761.66 million; neither is recorded as a lot cost because the VAT basis and scope are not stated. Contractor consortium led by Przedsiębiorstwo Budowy Dróg i Mostów Mińsk Mazowiecki with Astaldi and three other firms.

Design-build contract with PUT Intercor for about PLN 499.8 million, 36 months, signed on 5 March 2020 (first of three Mińsk – Siedlce contracts). Opened in two steps: 29 August 2024 (pl.wikipedia) and the last 3.6 km on 18 December 2024 (GDDKiA). Recorded length is the 12 km of the contract; the drawn centreline from the Kałuszyn junction to Groszki is 8.8 km, so the contract section apparently starts west of the junction node.

Last of the three Mińsk – Siedlce contracts: design-build with STECOL Corporation, about PLN 530.8 million, 36 months, signed on 28 January 2021 (date from pl.wikipedia). Opened on 18 December 2024, three months before the deadline, on a new alignment with a 600 m viaduct in the Kostrzyń valley. GDDKiA names the section Groszki – Siedlce Zachód (12.9 km); the 2021 release calls it Groszki – Gręzów (13 km). The drawn line ends 12.9 km after the Groszki junction, so the OSM Siedlce Zachód junction node lies further east than this contract end.

Siedlce bypass section of 12.4 km (pl.wikipedia; the tender text gives 12.5 km). pl.wikipedia records the tender of 10 October 2019 as won by Polaqua and the contract as signed on 7 April 2020; GDDKiA calls a 12.5 km contract of 7 April 2020 "Gręzów – Siedlce Zachód", so the section names differ between sources. The contract value was not found. Opened 8 August 2024 per pl.wikipedia; GDDKiA says 3.4 km of it opened with the Groszki section on 18 December 2024, which is recorded as the date the whole lot was open. Drawn length is 13.8 km from the end of the Groszki lot to the OSM Siedlce Południe junction.

Design-build contract with Strabag, 18.7 km (GDDKiA 2026; the signing release said almost 19 km, about PLN 700 million, 33 months, with a Borki junction). The first 8 km to Siedlce Wschód opened on 23 December 2025 and the rest on 26 June 2026. pl.wikipedia gives 18.8 km. The 2026 value of nearly PLN 589 million is recorded as stated; the contract was signed on 14 April 2021 (GDDKiA, pl.wikipedia).

Design-build contract with Intercor; GDDKiA 2026 gives 20 km and PLN 389 million for the section including about 2 km inside the Łukowisko junction, which opened before the May weekend 2026 with the Łukowisko – Biała Podlaska lot. Length 18 km from pl.wikipedia. The Siedlce Wschód – Łukowisko link (about 30 km) opened on 26 June 2026 and the old DK2 to Biała Podlaska became DK92. Signing date 1 April 2021 from pl.wikipedia.

Two contract sections, Łukowisko – Swory (12.5 km, Intercor, almost PLN 370 million at signing in April 2021, 33 months, VAT basis not stated) and Swory – Biała Podlaska (about 14 km; contract signed 1 April 2021 per pl.wikipedia, contractor not found). Opened before the May weekend, 29 April 2026 (pl.wikipedia; GDDKiA says 27 km plus 2 km in the Łukowisko junction). Contractor Intercor applies to the Łukowisko – Swory part. The motorway ends at the Biała Podlaska junction.

Tender for design and construction announced on 5 May 2025 (pl.wikipedia); GDDKiA said in 2026 that the contract would be signed within the year. Geometry follows the OSM proposed ways of A2 (about 31.5 km from Biała Podlaska to the border) cut by recorded lengths: 16.0 + 9.3 + 6.8 km.

Design-build contract with a consortium led by Mirbud with Budpol, signed on 10 June 2026 (GDDKiA, 26 June 2026); tender announced on 11 December 2024. Design phase 10 months, then 22 months of works. The ZRID permit has been issued. The press forecast in the release is access to the Koroszczyn lorry terminal in about three years; no official opening date is stated.

Last 6.8 km to the Belarus border. GDDKiA states that the ZRID procedure is suspended and depends on the geopolitical situation with Belarus (December 2024). No contract or dates.
