D2 motorway (Czech: Dálnice D2) is a highway in the Czech Republic. It runs from the City of Brno to the border with Slovakia^[1] at the Morava river near Lanžhot, from where the Slovak diaľnica D2 leads to Bratislava. The entire route is part of European route E65.

Plans for the motorway existed since early 1950s. In 1958, it was decided to prepare for the resumption of motorway construction, with plans to build a motorway linking Prague, Brno and Bratislava.^[2] The D2 motorway became part of the network of motorways and expressways in 1963 with the adoption of the concept of long-term development of the road network and local roads.^[2]

Construction on the D2 highway began in 1974;^[2] the first 11 kilometers (6.8 mi) opened in 1978. The last part of the motorway opened in 1980, when it was 141 km (88 mi) long. After the 1993 dissolution of Czechoslovakia, 61 km (38 mi) of the motorway remain in Czech Republic, with 80 km (50 mi) remaining in Slovakia.
