The mid-points show you the destination with an arrow, you can adjust that using Shift-Scrollwheel. You can target that into the shallow water.
The endpoint Roadsigns don't seem to have that, you can spin them but I can't tell where it ends up. I think your best bet is to have one mid-point on each shore and one endpoint on each shore.
Maybe the face of the under-construction endpoint has to face the water? That seemed to work for me just now
