What is the name of the canal that connects the Atlantic and Pacific oceans?

Answer: Panama Canal.

The Panama Canal is a 77-kilometre (48 mi) ship canal in Panama that joins the Atlantic Ocean and the Pacific Ocean and is a key conduit for international maritime trade.
The length of the Panama Canal is approximately 51 miles. A trip along the canal from its Atlantic entrance would take you through a 7 mile dredged channel in Limón Bay. The canal then proceeds for a distance of 11.5 miles to the Gatun Locks. This series of three locks raise ships 26 metres to Gatun Lake. It continues south through a channel in Gatun Lake for 32 miles to Gamboa, where the Culebra cut begins. This channel through the cut is 8 miles long and 150 metres wide. At the end of this cut are the locks at Pedro Miguel. The Pedro Miguel locks lower ships 9.4 metres to a lake which then takes you to the Miraflores Locks which lower ships 16 metres to sea level at the canals Pacific terminus in the bay of Panama.
