Greek National Road 15 (Greek: Εθνική Οδός 15), abbreviated as the EO15, is a national road in northern Greece. It connects Agios Germanos, near the border with North Macedonia, with the Greek National Road 6 near Kalampaka. It passes through Kastoria, Siatista and Grevena.

Route

[edit]

The EO15 is officially defined as a north–south road that runs within northern Thessaly and Western Macedonia: it branches off the EO6 at Mourgani bridge [el], north west of Kalabaka, and heads north towards Agios Germanos, passing through Grevena, Siatista (Bara), Neapoli, Kastoria and Trigono. The EO15 overlaps with: the EO20, between Siatista and Neapoli; and the EO2, between Vatochori and Trigono.[2]

Today, the A2, A29 and A3 motorways run roughly adjacent to and connect with the EO15, between Mourgani and Kastoria: the EO15 also connects with the EO26, near Agiofyllo [el].
