Isthmia Submersible Bridge

The Isthmia subducting bridge, is the one of the two ‘sinking’ bridges, originally called subducting bridges, that exist near both ends of the Corinth Canal. Rather than rise to allow a ship to pass, they sink down to the canal floor, 11 meters below the surface. The maximum allowed uniform load of the Isthmia bridge, is 300 kilograms/m². The vertical sinking speed is four (4) meters/minute; therefore, the sinking or refloating procedure lasts about 3,5 to 4 minutes. The bridge was constructed in 1988 and submerge approximately 10,000 times every year. Visitors can park next to the Isthmia bridge and watch the bridge sink. There are a couple of tavernas nearby, on both sides of the Corinth Canal, where you can sit and enjoy the whole procedure. It is very interesting to watch although crossing the bridge on foot after it has been submerged is very slippery, so you need to hold the handrails.
