Greek National Road 8a (Greek: Εθνική Οδός 8a, abbreviated as EO8a) was a toll road in the Attica, Peloponnese and West Greece regions. It connected Athens with the cities of Corinth and Patras. It was built in the 1960s as a replacement for the old National Road 8 as the major route to the Peloponnese, and bypasses most towns. The National Road 8a has gradually been upgraded to a motorway, the A8. Since April 2017, the complete length of the A8 motorway has been operational.^[1]

The EO8a started east of Eleusis, where it branched off the old GR-8 as a limited-access dual carriageway. Between Megara and Kineta the motorway passed through several tunnels. Its western end was the interchange with the A5 motorway, near Rio, northeast of Patras.

The total length of the route was 215 km. The eastern section, between Eleusis and Corinth, was part of European route E94. The western section, between Corinth and Rio, was part of European route E65.^[2]
