S1 expressway (Pyrzowice – Dąbrowa Górnicza – Mysłowice – Bielsko-Biała – Żywiec – Zwardoń)

Junction Pyrzowice (A1) to junction Pyrzowice Lotnisko, 1.9 km, opened to traffic on 1 June 2012 (pl.wikipedia).

Opened on 20 November 2006 as a single carriageway (pl.wikipedia). The second carriageway was tendered on 14 February 2018 (an earlier tender of October 2015 was cancelled), the contract was signed on 26 November 2018 and the carriageway opened on 17 May 2021. The lot ends at the old Podwarpie junction; the 1.5 km Podwarpie link listed by pl.wikipedia without a date is not drawn.

Rebuild of the dual carriageway DK1 to expressway standard (2x2), removing the at-grade junctions. Design-build contract signed on 11 September 2020, contractual completion 11 December 2023. The drawn centreline starts at the Podwarpie junction (ref 4) and is 7% shorter than the sourced 6.95 km; the sourced length is kept.

Wschodnia obwodnica GOP, built in 1978–1983 (pl.wikipedia, 35.4 km counting the part to Tychy that lies outside the target S1 route). The opening year is taken as the end of the 1978–1983 construction range, since the page gives no opening date, so 1983 is a latest bound and sections may have opened earlier. Length measured from OpenStreetMap geometry between the Dąbrowa Górnicza Pogoria junction and the start of the Kosztowy II lot.

Design-build contract signed on 4 July 2022. The ZRID permit was issued on 31 January 2025 (applied for on 28 April 2023), which moved the works front to spring 2025 and the original October 2025 deadline out of reach. GDDKiA gives a planned works completion of September 2027 and plans opening to traffic in Q4 2027, with progress above 66% in September 2026. The drawn centreline starts at the Kosztowy II interchange (no OpenStreetMap junction node, position from the construction ways and pl.wikipedia) and is 4% shorter than the sourced 10 km; the sourced length is kept.

Design-build contract signed on 30 November 2021; ZRID issued on 13 August 2024. GDDKiA lists the length as 2.86 km of S1 plus 2.7 km of DK44. The drawn centreline between the two junctions is 15% longer than the sourced 2.86 km; the sourced length is kept. Site handed to the contractor on 20 August 2024.

Design-build contract signed on 14 May 2020 with the Porr / Duna Polska (formerly Mota-Engil Central Europe) consortium; ZRID issued on 12 September 2022; contractual completion 14 August 2023, 28 July 2025 after an annex. GDDKiA says the value stood at almost 1.2 bn PLN after contract changes and a higher indexation limit. The end of the lot (km 28+030) has no OpenStreetMap junction node: the boundary is placed 4.42 km beyond the Brzeszcze junction (km 23+607). The drawn centreline is 8% shorter than the sourced 15.8 km; the sourced length is kept. Site handed to the contractor on 15 September 2022.

Design-build contract signed on 3 August 2020 for 586.71 mln zł; GDDKiA says the value stood at almost 681 mln zł after contract changes and a higher indexation limit. ZRID issued on 27 September 2022. The start of the lot (km 28+030) has no OpenStreetMap junction node and is placed 4.42 km beyond the Brzeszcze junction. The drawn centreline ends at the Hałcnów (Suchy Potok) junction and is 12% shorter than the sourced 11.87 km; the sourced length is kept. Works began in October 2022.

Part of the north-east bypass of Bielsko-Biała (11.9 km Komorowice – Mikuszowice per pl.wikipedia), whose Rosta – Mikuszowice section (9.1 km) opened on 28 October 2011 and Komorowice – Rosta (2.8 km) on 19 August 2011. OpenStreetMap carries ref S52 on the Komorowice – Hałcnów part, so only Hałcnów – Mikuszowice is drawn here. Length measured from OpenStreetMap geometry.

6.1 km including the Wilkowice junction, opened on 6 November 2014 (pl.wikipedia). Signed S69 until 4 August 2016. The drawn centreline is 7% longer than the sourced length; the sourced length is kept.

9.5 km, opened on 24 July 2015 (pl.wikipedia). Signed S69 until 4 August 2016. The lot ends at the Żywiec Soła junction; the drawn centreline is 4% shorter than the sourced length, which is kept.

Two parts of 2.8 km (Żywiec – Browar) and 4.9 km (Browar – Przybędza), 7.7 km in total, opened in January 2007 as part of the S69 (pl.wikipedia); the page gives no day. The access road from the Żywiec junction to the Soła bridge (1.5 km) was opened on 8 January 2007. The drawn centreline is 10% shorter than the sourced length, which is kept.

8.5 km with two twin-tube tunnels of 830 m and 1000 m and a viaduct of almost 1 km; 4.8 km is dual carriageway (the tunnel stretch and between the tunnels) and 3.7 km single carriageway. Design-build contract signed on 10 October 2019 after the tender of 17 January 2018. The drawn centreline is 1% shorter than the sourced length.

2.9 km, single carriageway, opened on 8 January 2007 together with 1.8 km of upgraded access road to Milówka (pl.wikipedia). Szare has no OpenStreetMap junction node, so the boundary is placed by the sourced length, 2.9 km from the Milówka junction.

4.7 km, single carriageway, contract signed in October 2007 and opened on 5 March 2010 (pl.wikipedia). It includes the Emilia tunnel (678 m), the first road tunnel built outside a city in Poland, with two parallel tubes, one of them for technical and evacuation use. Neither boundary has an OpenStreetMap junction node; the start follows the Milówka – Szare cut, and the end is placed by the sourced length of the next lot (1.8 km) counted back from the Zwardoń end of the drawn road. The drawn centreline is 14% longer than the sourced 4.7 km; the sourced length is kept.

1.8 km, single carriageway, contract signed in June 2007 and opened on 28 December 2008 (pl.wikipedia). The boundary is placed by the sourced length counted back from the end of the S1 ways in OpenStreetMap at Zwardoń. The final 1.4 km to the Zwardoń/Myto – Skalité border (works completed December 2004 per pl.wikipedia) is not drawn.
