Low water crossing for a submersible bridge that does not move at all.

A true submersible bridge is used on navigable waterways and is actively lowered into the water.

A low-water bridge is sometimes called a submersible bridge, but this is a misnomer.

Two submersible bridges exist across the Corinth Canal, one at each end, in Isthmia and Corinth.

The term submersible bridge is also sometimes applied to a non-movable bridge that is designed to withstand submersion and high currents when the water level rises.

A submersible bridge is a type of movable bridge that lowers the bridge deck below the water level to permit waterborne traffic to use the waterway.

The submersible bridge's primary advantage over the similar lift bridge is that there is no structure above the shipping channel and thus no height limitation on ship traffic.

In 1988 submersible bridges were installed at sea level at each end of the canal, by the eastern harbour of Isthmia and the western harbour of Poseidonia.

Today, two road bridges, two railway bridges and two submersible bridges at both ends of the canal connect the mainland side of the isthmus with the Peloponnese side.
