A90 motorway (Greece)

The A90 motorway, also known as the Northern Road Axis of Crete (Greek: Βόρειος Οδικός Άξονας Κρήτης, ΒΟΑΚ),^[1][2] is a mixture of motorway and limited-access roads that form the northern backbone of the national highway network in Crete, southern Greece. It is about 310 km, starting in Kissamos and ending in Sitia.

The A90 currently has three sections of motorway, where it bypasses the cities of Chania, Rethymno and Heraklion. The A90 also forms part of the European E65 road from Kissamos to Chania, and the E75 road for the remainder.

A90 follows the route of the old Highway 90, (except for the Gournes-Hersonissos section in Heraklion where a viaduct was built in the Aposelemi Gorge bypassing the former road route). A90 replaced the old Highway from the late 60's.

Construction began in the 1990s, but to date, only sections bypassing the major cities were turned into a four-lane motorway with interchanges, while for the most part the highway remains a trunk road. Works between Hersonissos and Neapoli began in 2024. The expected completion date of the entire motorway is 2031.^[3]
