Corinth is a major road hub. The A7 toll motorway for Tripoli and Kalamata, (and Sparta via A71 toll), branches off the A8/European route E94 toll motorway from Athens at Corinth.
Corinth is the main entry point to the Peloponnesian peninsula, the southernmost area of continental Greece.

By sea:
The port of Corinth, located north of the city centre and close to the northwest entrance of the Corinth Canal, at 37 56.0’ N / 22 56.0’ E, serves the local needs of industry and agriculture. It is mainly a cargo exporting facility.
It is an artificial harbour (depth approximately 9 metres (30 ft), protected by a concrete mole (length approximately 930 metres, width 100 metres, mole surface 93,000 m2). A new pier finished in the late 1980s doubled the capacity of the port. The reinforced mole protects anchored vessels from strong northern winds.
Within the port operates a customs office facility and a Hellenic Coast Guard post. Sea traffic is limited to trade in the export of local produce, mainly citrus fruits, grapes, marble, aggregates and some domestic imports.
The port operates as a contingency facility for general cargo ships, bulk carriers and ROROs, in case of strikes at Piraeus port. There is a ferry line (RORO) connecting Corinth to Italy.
