The image below was cropped from the NOAA world topographic relief map. The image shows a line coming from the area W of the Bermuda Island and proceeding to the Andros Island chain where it abruptly ends.

As shown above another interesting alignment can be seen before the line enters into the North East Providence Channel before stopping at the Andros Island. Shown in the triangular features study, the Andros Island is in the direct vacinity where the large, terraformed, triangular formations have been revealed.

Below is a close-up of this area. Pay close attention to the existing line which runs directly between the walls of the North East Providence Channel:

Notice in the close-up of the North East Providence Channel that the lines seem to be split with one line on top of the other. The bottom line is the line that leads directly into the North East Providence Channel of the Bahamas. It almost seems that the Channel was created artificially. Notice the channel is around the same depth as the lines, over 2000 ft deep. Also note that directly to the North of this channel is the Berry Islands where the recent Triangular terraformed land features have been found by Satellite Discoveries:
