Greek National Road 8A (, abbreviated as
EO8A) is a
toll road in the
Attica,
Peloponnese and
West Greece regions. It connects
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 is gradually being upgraded to a motorway, the
A8. , the easternmost section between Corinth and
Eleusis of the A8 motorway has been completed.
