An 80 km section between the M0 junction and Győr (120 km west of Budapest by road) will be widened to six lanes.

According to the statement, the project will also include installing a smart lane system, allowing traffic to be rerouted to the emergency lane when necessary.

The ministry added that the concession contract will be technically modified to ensure alignment with European Union regulations.

The first section of the motorway opened in the 1970s, reaching the Austrian border at Hegyeshalom in 1996. It follows the route of the old Route 1 one-lane highway.
