Greek National Road 1 is the longest highway in
Greece. The highway begins at Kifissou Avenue or north of the
Bay of Phaliro up to Efzoni at the border with the former Yugoslav
Republic of Macedonia, where it continues as the M1. Before the European routes numbers were changed, the northern part from Efzoni to
GR-2 was E5N. Today, the entire road is run by
E75. The motorway is tolled with the exception at the Aphidna tolls, southward only. One toll booth has been abandoned.
