D46 motorway (Czech: Dálnice D46), formerly Expressway R46 (Czech: Rychlostní silnice R46) is a motorway in south-eastern Czech Republic, which runs from Vyškov via Prostějov to Olomouc where it ends and connects to the national road network.

In the time-based toll system, the D46 motorway is tolled along its entire length, i.e. from the Vyškov-východ off-ramp (exit 1) to the end of the motorway after the Slavonín off-ramp (exit 37).

[3] Capacity-wise, however, the narrow S 20.5/100 category road is no longer sufficient[according to whom?].

Therefore, all upcoming projects concern only construction modifications of already completed sections.
