===The bridges===

The town is now connected to mainland Greece by two bridges, the "Sliding Bridge" in the west at the narrowest point of the [[Euripus Strait]] and a suspension bridge.

The [[Euripus Strait]] which separates the city and the island from the mainland was bridged in 411 BC with a wooden bridge. In the time of [[Justinian]] the fixed bridge was replaced with a movable structure. The Turks replaced this once again with a fixed bridge. In 1856, a wooden swing bridge was built; in 1896, an iron swing bridge, and in 1962, the existing "sliding bridge"; the construction works of the 19th century destroyed the most part of the medieval castle built across the bridge. The [[Euripus Bridge]] or Chalcis Bridge, a cable-stayed suspension bridge opened in 1993, joins Chalcis to the mainland to the south.

A special tidal phenomenon takes place in the strait, as strong tidal currents reverse direction once every six hours, creating strong currents and maelstroms.<ref name=EuripusStraits>{{cite journal | url=http://articles.adsabs.harvard.edu/full/1929AN....236..321E | title=The problem of the tide of Euripus | author=Eginitis, D. | journal=Astronomische Nachrichten | year=1929 | volume=236 | pages=321–328|bibcode = 1929AN....236..321E | doi=10.1002/asna.19292361904 | issue=19–20 }} See also the commentary about this explanation in {{cite journal | title=Les marées de l'Euripe | author=Lagrange, E. | journal=Ciel et Terre (Bulletin of the Société Belge d'Astronomie) | year=1930 |language=fr | volume=46 | pages=66–69 | bibcode=1930C&T....46...66L}}</ref><ref>{{cite web | url=http://www.evia.gr/en/node/1250 | title=Evia Island | publisher=Evia.gr | work=Chalkis | access-date=29 June 2013}}</ref>
