Route
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, 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.
