The Chalkida Bridge is in the city of Chalkida, in Euboea(Evia).

A bridge has always been standing there since ancient times,connecting Central Greece and Euboea. Once wooden and later metal, the bridge contributed to the communication of Evia with the rest of Greece and the economic development of the region.

Today on the spot you will see two bridges, the so-called Old Bridge and the high Bridge of Chalkida.

The Old Bridge is metallic and electric, so that it can open and allow the passage of ships. On the side there are pavements, from which people usually watch the phenomenon of the Evripos tide. The Old Bridge faced serious traffic congestion, which was significantly reduced by the construction of the new bridge, known as High Bridge of Chalkida.

Completed in 1993, the High Bridge of Chalkida helped greatly in traffic decongestion and the further development of Evia. The bridge is cabled with a total length of 695 meters, width 12,5 meters and height of 34,5 meters. Brace yourselves for once you find yourself here, you can also do bungee jumping off the High Bridge Chalkida.

Both bridges are major attractions and the unique ways in which you can get by car to Evia.

You can observed the famous Evripos tide in the Evripos strait in Evia.

The Evripos tide is a unique phenomenon that occurs in the strait of Evripos. At this point, water runs constantly changing direction of movement about every six hours, sometimes to the South and sometimes to the North with Evian Gulf as an intermediate small space where they remain stationary. This constant motion gave the sea and the area the nickname "crazy waters".

This phenomenon has been observed since ancient times, puzzling some of the leading thinkers of the era, such as Eratosthenes and Aristotle. Actually, it is said that he dived into the waters trying to solve the mystery of their motion.

Today the accepted explanation for this very special phenomenon is that the Aegean tidal wave enters the northern and southern Gulf of Evia with time difference, thus creating this spectacular movement.

Whatever the explanation, this is a very special and beautiful phenomenon worth seeing first hand when you find yourself in Chalkida.
