The 21-km long Prague – Mirošovice segment was completed in 1971, and the 205-km long route to Brno was finished in 1980. In Slovakia, construction started in 1973 with the 14-km long Ivachnová – Liptovský Mikuláš section, together with the construction of the Liptovská Mara dam. The 19-km Prešov – Košice motorway was added in 1980. In the late 1980s and the early 1990s the 19-km long Brno – Vyškov segment was built, along with another 20 km from Liptovský Mikuláš to Hybe in Slovakia. After the dissolution of Czechoslovakia, construction was no longer planned to Slovakia, but instead to Lipník nad Bečvou (the replacement of the planned route is the R49 expressway). Due to growing traffic near Prague, the first segment to Mirošovice was widened from 4 lanes to 6 lanes, and there are similar plans for widening around Brno as well. After the dissolution, no new sections were built. In 2002, construction of an 18-km long extension from Vyškov eastwards started. It was opened in 2005. More extensions eastwards were opened in 2008, 2009 and 2010; in 2011, the motorway reached the junction with the R55 expressway and the R49 expressway near Hulín, and the route curved north to Přerov (and Lipník nad Bečvou). The segment from Lipník nad Bečvou to Ostrava was constructed from 2004 – 2009. Due to historical reasons it was named the Motorway D47; however, it was opened as part of the D1. The segment from Ostrava to the Polish border (and Autostrada A1) opened in late 2012, but only for cars under 3.5 tonnes, because the Polish side had problems with the bridge at Mszana village. From 2014 the bridge is open, and it is possible to drive from Ostrava to the Polish border and on to Katowice. The Přerov – Lipník nad Bečvou segment opened in December 2019. The only section which is not yet completed is the Říkovice – Přerov segment. Construction on this segment started in 2022, with an expected completion date in 2026.
