A brief description of the project would be the following: "A channel would be opened which, starting opposite the Cartuja, upriver from Seville, would join up with the San Juan branch-off at the town of the same name. This channel, the axis of the whole lot and, actually, another cutoff, would divert the river as it flowed through Seville shifting it towards the Vega de Triana where the new river channel opened up.

In this way the whole port area would become a closed harbour and to enter it a lock was constructed sideways to the canal enclosure.
The new canal can be seen slightly to NW and the old riverbed and port still exist to the north of the locks.
