Expressway R43 (Czech: Rychlostní silnice R43) is an expressway in Czech Republic. If completed, it will connect cities Brno and Moravská Třebová, and the D1 highway with the R35 expressway. First project in that route was created after Munich Agreement by Nazi Germany, as an ex-territorial Autobahn A88 Breslau - Wien, passing through territory of The Second Republic of Czechoslovakia with custom houses on all exits. Construction began in April 1939, during German occupation of Czechoslovakia and was halted on 73 km of route in April 1942 due to the increasing demands of World War II. After war construction was not resumed, whole route was abandoned.
