The M1 motorway is a toll motorway in northwestern Hungary, connecting Budapest to Győr and Vienna. 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.

Győr is the main city of northwest Hungary, the capital of Győr-Moson-Sopron County and Western Transdanubia region, and – halfway between Budapest and Vienna – situated on one of the important roads of Central Europe. It is the sixth largest city in Hungary, and one of its seven main regional centres. The city has county rights.
