Yes, there are several, most notably the 50.5 km Channel Tunnel connecting the UK and France, which has the longest undersea section in the world at 37.9 km. Other major examples include Japan's Seikan Tunnel (53.85 km total length) and the Transbay Tube in San Francisco.
The Channel Tunnel is made of three separate tunnels running parallel to each other. One train tunnel running south (UK to France), one train tunnel running north (France to UK) and one service tunnel.

The Channel Tunnel is the longest undersea tunnel in the world: its section under the sea is 37km long. It is actually composed of three tunnels, each 50km long, bored at an average 40m below the sea bed. They link Folkestone (Kent) to Coquelles (Pas-de-Calais).
Opened in 1994, it remains the only fixed link between Great Britain and the European mainland. The tunnel has the longest underwater section of any tunnel in the world, at 37.9 km (23.5 miles), and reaches a depth of 75 m (246 ft) below the sea bed and 115 m (377 ft) below sea level.
