M6 motorway (Budapest – Dunaújváros – Szekszárd – Bóly – Ivándárda)

Opened on 23 September 2008, after the section beyond Érdi tető. Length (7 km) from the kilometre markers in the hu.wikipedia junction list (M0 junction at km 15, Érdi tető at km 22); the drawn centreline measures about 6.5 km. No concessionaire or builder is named for this stretch; the article says Magyar Közút Nonprofit Zrt. operates it.

Length measured from OpenStreetMap geometry. Opened on 11 June 2006, the first section of the M6. Concession company M6 Duna Autópálya Koncessziós Zrt., founded in 2004 by Bilfinger Berger Project Investments GmbH, Porr Infrastruktur GmbH and Swietelsky International Baugesellschaft GmbH; the page does not name the builders. The en.wikipedia opening list gives 68 km for this section; it is not used because the hu.wikipedia junction list places Érdi tető at km 22 and the M8 junction at km 75, about 53 km apart.

Length measured from OpenStreetMap geometry. Opened on 31 March 2010, the same day as Szekszárd – Bóly: hu.wikipedia gives that date for Dunaújváros – Bóly and Index (31 March 2010) reports this section opened that day on a last-minute temporary permit. Concession company M6 Tolna Autópálya Koncessziós Zrt.; the page does not name the builders. The cut between this lot and the next is the Szekszárd-dél junction (km 151), an assumption: the page names the concession split at Szekszárd without a junction.

Length measured from OpenStreetMap geometry. Opened on 31 March 2010 and ends at the M60 split near Bóly (km 191.6). Concession company Mecsek Autópálya Koncessziós Zrt., formed by Strabag AG, Colas S.A., Bouygues Travaux Publics S.A., John Laing Infrastructure Limited and Intertoll-Europe Zrt.; the page does not name the builders. Four tunnel pairs: Bátaszék 1,331 m, Geresd 399 m, Baranya 865 m and Véménd 418 m (3.01 km per carriageway), and nine larger bridges. From km 191.6 the main carriageways were not built and traffic ran on the collector lanes until the extension towards the border.

Length measured from OpenStreetMap geometry. Opened on 2 May 2024. NIF Zrt. signed the contract for the whole Bóly – Ivándárda stretch on 12 December 2020 with Strabag Építő Kft. and Duna Aszfalt Út és Mélyépítő Kft. for more than HUF 90 billion; the page does not say whether that is net or gross and it covers both lots, so no figure is recorded. Works area handed over and archaeology from 10 February 2021, earthworks planned from late March 2021; contract deadline May 2024. Ends at the Lippó junction.

Last 5 km to the Croatian border at Ivándárda, handed over on 6 October 2025 with the Croatian A5 section from Pélmonostor to the border; traffic started on 7 October. Length (5 km) as stated in the hu.wikipedia article; the drawn centreline measures about 6.5 km. Same contract and contractors as Bóly – Lippó (see that lot for the contract).
