I've seen variants of this explanation offered up before. IIRC, this underwater "bridge" is a hard reef of some sort. As others have already pointed out, maybe this is how God chose to do it. Still a miracle of course. Or maybe this brilliant scientist would like to recreate the event as it happened, allowing the Israelites to cross precisely when they needed to, then bringing the water back in on the Egyptians precisely when they needed to be stopped. :-)

Heard this about 30 years ago from a theology student. The truth is...believe what you wish.

My brother is a scuba diver and a very religious person. He claims that researchers have sent down camera robots in the Red Sea and these cameras have recorded what appears to be decayed chariot pieces.
