Authorities will conduct an emergency response drill at the Artemisio Tunnel, on the section of the national highway between Corinth and Tripoli in the Peloponnese, between 9 p.m. on Tuesday and 6 a.m. on Wednesday.

During those hours, both lanes between the Sterna and Tripoli-Voreia intersections will remain closed.

Motorists traveling to Tripoli or Corinth during this time will be diverted to the old national highway running through the Achladokampos area.
