D8 motorway (Praha – Lovosice – Ústí nad Labem – German border)

Stavba 0801, km 0–9.6. Dates and length from the cs.wikipedia section table and text and the ŘSD publication (started October 1990, opened 23 July 1993, fully completed December 1993). Category D 26.5/120. The 2.248 km Březiněves – Zdiby link on the Prosecká radiála is not part of the motorway and is not drawn. The line starts at the Zdiby junction (OSM motorway_junction, ref 1), where the section table puts km 0; the drawn line is about 5% longer than the recorded 9.6 km because the Úžice end is cut at the junction node.

Stavba 0802, km 9.6–18.5, with the Vltava bridge and the Nová Ves junction. Dates and length from cs.wikipedia and the ŘSD publication (started December 1993, opened 18 October 1996, fully completed April 1997). Category D 26.5/120. Cost as stated on the archived 2008 enthusiast page dalnice-silnice.cz, which cs.wikipedia cites.

Stavba 0803, km 18.5–34.851, with the Roudnice nad Labem junction. Started on 26 October 1998, after most of 0804 had opened; opened on 18 June 2001 (fully completed August 2001), which gave a continuous motorway from Zdiby to Lovosice. Category D 26.5/120. No cost is recorded: cs.wikipedia gives 1.88 billion CZK "in the 1990s", while the archived dalnice-silnice.cz page it cites gives 1.4 billion CZK.

Stavba 0804, km 34.851–48.276, with the 1,183 m bridge over the Ohře. First work started in July 1995 on that bridge, official construction start October 1996. Opened on 26 October 1998 except the first 800 m with the Doksany junction, which were built with 0803 and opened in June 2001. Category D 26.5/120. Cost as stated on the archived 2008 enthusiast page dalnice-silnice.cz, which cs.wikipedia cites.

Stavba 0805, km 48.276–64.689, through České středohoří with the Vchynice, Oparno (275 m) and Dobkovičky bridges, the Prackovice viaduct and two tunnels (Prackovice 260/270 m, Radejčín 600/620 m, 890 m in total, longer tube of each). Only the roughly 4 km between the Lovosice and Bílinka junctions opened in May 2012. The Prackovice landslide of 7 June 2013 shifted part of the carriageway about 25 m and required a full rebuild there. The remaining 12.7 km from Bílinka to Řehlovice opened on 17 December 2016, with the Prackovice viaduct temporarily carrying one lane per direction on a single carriageway; it reached full profile on 20 September 2017. The leaflet gives the contract price; cs.wikipedia mentions remediation stages of 70 and 400 million CZK, which are not recorded as lot cost. Construction start is October 2007 in the ŘSD leaflet; cs.wikipedia gives the official start as 6 November 2007. A 2018 ŘSD publication gives the contract price as 9,850,778,000 CZK excl. VAT. Length from the leaflet and cs.wikipedia; the drawn centreline is 2.7% shorter.

Stavba 0806, km 64.689–68.864, the oldest part of the D8, with six motorway bridges including the Stadice, Koštov and Trmice bridges. Built ahead of the rest because the Chabařovice coal pit threatened the only road link between Teplice and Ústí nad Labem; with the road I/63 it served as an alternative link until the next section opened in December 2006. Its total cost was 1,032 million Kčs (dalnice-silnice.cz), a defunct currency, so it is not recorded as a figure. The boundary with 0807 is cut at the present Trmice junction, so the drawn 4.4 km exceeds the sourced length.

Stavba 0807, km 68.864–92.208, over the Krušné hory to the border at Krásný Les/Breitenau, joining Germany's A17. Opened on 21 December 2006 (ŘSD publication, cs.wikipedia). Construction began in November 2004 (section table; ŘSD: autumn 2004), with the Panenská tunnel driven from autumn 2003. Panenská, the longest motorway tunnel in Czechia, has tubes of 2,167.7 and 2,115.7 m; the Libouchec tunnel has tubes of 535 and 454 m in the ŘSD section description (the same publication gives 504 and 520 m elsewhere). profile.tunnelKm sums the longer tube of each (2.703 km). The cs.wikipedia text splits the section into 0807/I Trmice – Knínice (12.244 km, D 28.0/100) and 0807/II Knínice – border (11.475 km, D 27.5/120); those parts sum to 23.719 km against 23.344 km for the section, so one lot is kept with the official figure. Both parts opened together. No cost is recorded: the 22.334 billion CZK on cs.wikipedia has no price year and is not on the archived page it cites.
