R1 expressway (Trnava – Nitra – Žiar nad Hronom – Zvolen – Banská Bystrica)

Length is the 13.1 km of the sk.wikipedia section table, which says the whole Trnava – Sereď section was opened on 15 July 2000. Historiadialnic.sk dates the 6.775 km Trnava D1 – Sereď part, started in November 1997. Drawn line runs from the Trnava-sever exit, where the OSM expressway begins, to the Sládkovičovo junction (13.6 km), taken as the table's Sereď-západ because the table's section lengths add up to it from Báb.

Three sk.wikipedia sections (2.4 + 4.5 + 1.5 km) built first as half profile and completed in 1998. Historiadialnic.sk dates the second carriageway of Sereď – Šoporňa (6.795 km) from 26 March 1997 and its opening to 1998 without a day. Drawn line runs from the Sládkovičovo junction to the Šoporňa junction, which OSM signs for Pata (8.5 km).

Length from the sk.wikipedia table (start and opening 1997 and 1998). The days are those historiadialnic.sk gives for the longer Šoporňa – Báb section (9.465 km). Drawn line runs from the Šoporňa junction, which OSM signs for Pata, to the Veľké Zálužie junction, signed for Báb (6.8 km).

One of the reconstructions of road I/51 into a half-profile expressway before 1989 (sk.wikipedia); only years are given. The R1A branch into Nitra leaves at the Nitra západ junction and is not drawn.

Part of the second PPP package, Nitra – Tekovské Nemce (sk.wikipedia). Length from historiadialnic.sk and the sk.wikipedia section text (the sk.wikipedia table says 14.3 km). Drawn line ends at the Nitra-východ junction (12.4 km). Concession lot: GRANVIA, a.s. is the concessionaire and Granvia Construction a.s. (Eurovia CS group) designed and built it; Granvia Operation, s.r.o. (Vinci Concessions) operates it (MDV PPP page). The concessionaire's site says main works began on 1 September 2009; the 28 August 2009 start is historiadialnic.sk's. Concession payments are not a construction cost and are not recorded.

Section without exits in the sk.wikipedia table; drawn line ends at the Zlaté Moravce junction, which serves Beladice (18.8 km). Concession lot: GRANVIA, a.s. is the concessionaire and Granvia Construction a.s. (Eurovia CS group) designed and built it; Granvia Operation, s.r.o. (Vinci Concessions) operates it (MDV PPP page). The concessionaire's site says main works began on 1 September 2009; the 28 August 2009 start is historiadialnic.sk's. Concession payments are not a construction cost and are not recorded.

Includes the Zlaté Moravce junction. Tekovské Nemce has no junction, so the drawn end is cut 14.31 km after Zlaté Moravce (14.1 km drawn). Concession lot: GRANVIA, a.s. is the concessionaire and Granvia Construction a.s. (Eurovia CS group) designed and built it; Granvia Operation, s.r.o. (Vinci Concessions) operates it (MDV PPP page). The concessionaire's site says main works began on 1 September 2009; the 28 August 2009 start is historiadialnic.sk's. Concession payments are not a construction cost and are not recorded.

Length and dates from historiadialnic.sk. The sk.wikipedia table gives 7.1 km for this section (2004 start, 2005 opening); the sourced 2.772 km is kept and matches the 2.9 km drawn between the end of the PPP lot and the Hronský Beňadik junction.

Sum of three historiadialnic.sk sections: Hronský Beňadik – Nová Baňa 4.363 km, Nová Baňa bypass 5.303 km and Nová Baňa – Rudno nad Hronom 3.225 km. Doprastav, a.s. built the Nová Baňa bypass (sk.wikipedia); builders of the other two parts are not named. Rudno nad Hronom has no junction, so the drawn end is cut 5.485 km before the Žarnovica junction.

Length and dates from historiadialnic.sk. sk.wikipedia names Doprastav, a.s. and Strabag, a.s. as builders of Rudno nad Hronom – Žarnovica and gives a cost of 2.217 billion SKK for a 9.955 km section of that name; that length differs from this lot, so the cost is not recorded.

Length from historiadialnic.sk (4.47 km; sk.wikipedia table 4.4 km). Opened as half profile in 1998 and completed in 2006. Drawn from the Žarnovica junction to the Žarnovica-sever junction (4.9 km).

Date of opening from historiadialnic.sk; the sk.wikipedia table gives 2010 for this stage. Includes the Bzenica junction and 11 bridges (sk.wikipedia). Drawn line ends at the Žiar nad Hronom-západ junction (9.1 km).

Opening day from historiadialnic.sk. The whole Žarnovica – Šášovské Podhradie section was first due in June 2010 (sk.wikipedia). Includes the junction with the R2 at Žiar nad Hronom and 10 bridges. Drawn line ends at the Žiar nad Hronom-východ junction (8.7 km).

Built in the 1980s on the line of the former first-class road (sk.wikipedia); only years are given. Includes the Hronská Breznica and Hronská Dúbrava junctions. The next lot is 2.885 km long and no OSM junction fits that distance back from Kováčová, so the drawn end is placed by the sourced length, before the Zvolen-Stráže junction (15.9 km drawn). OSM has a Budča junction about 3.5 km earlier, which does not fit the sourced lengths.

Replaced the first-class road around Zvolen (sk.wikipedia, which names Doprastav, a.s. as builder and says 2001–2006; the dates here are historiadialnic.sk's and the sk.wikipedia table's 2004 opening). Length 2.885 km from historiadialnic.sk (the sk.wikipedia text says 2.855 km). The drawn start is placed by this length.

Sum of the sk.wikipedia sections Sliač (Kováčová) – Kremnička 11.9 km and Kremnička – Banská Bystrica juh 1.9 km, both 1972–1975; built as a rebuild of road I/66. Drawn line ends at the Banská Bystrica-Radvaň junction (14.0 km).

Includes the Radvaň, centre and Podlavice junctions (sk.wikipedia); only years are given. Drawn line ends at the Banská Bystrica-sever junction.

Length 5.14 km from historiadialnic.sk (sk.wikipedia table 5.6 km). The drawn line is 4.9 km, 5% shorter. It runs past the Banská Bystrica-východ junction along the OSM motorway and single-carriageway R1 ways to the start of the extension under construction, where sk.wikipedia lists a temporary connection to road I/66; the sourced length is kept. Concession lot: GRANVIA, a.s. is the concessionaire and Granvia Construction a.s. (Eurovia CS group) designed and built it; Granvia Operation, s.r.o. (Vinci Concessions) operates it (MDV PPP page). The concessionaire's site says main works began on 1 September 2009; the 28 August 2009 start is historiadialnic.sk's. Concession payments are not a construction cost and are not recorded.

3040 m extension of the R1 east of Banská Bystrica with the Šalková junction, a new bridge over the Hron and a relocation of road I/66. The award date is that of the NDS press release on the contract; the signing day itself was not found. The recorded start is the foundation-stone ceremony of 23 April 2024; the sources give no earlier site-work date. The tender expected a 960-day build. sk.wikipedia tabulates a contractual end of November 2026 and an opening in December 2028 and cites TASR of 23 November 2025 on NDS reporting problems with utility relocations; no official opening date was found, so none is recorded. Drawn from OSM construction ways (2.8 km, 8% shorter); a short stretch is drawn on the opposite carriageway where OSM lacks the other, and it starts where the drawn northern bypass ends.
