How will the landmass extend westward if westward is currently full of water? If the sea level goes up 5' or whatever, won't it advance from both eastward and westward directions, until tides just eat the sand?
The barrier islands exist as a function of wave action moving sand around. As sea level rises, the barrier islands get pushed shoreward. Pamlico Sound is very shallow, never more than 25ft deep over its vast expanse. To learn how this works, look up "marine transgression". Here is a slideshow that contains some pertinent diagrams. I don't have sound on this computer so hopefully the narrator isn't saying anything stupid. :p

Does that effect still apply if the sea level rises enough that water starts seriously encroaching on the actual landmass shoreline? Or will the barrier islands just end up within the former confines of the landmass shore?

NC DOT can only consider past and current erosion trends when modeling future shorelines but can not use sea level rise except as defined by the statute and the statute prohibited any sea level rise predictions from 2012 through 2016, the period during which the bridge was designed. Sea level rise modeling was excluded from the bridge design work.

When they start building it and it ends up a giant boondoggle due to poor planning they will blame it all on the Demonrats because it is their fault that the water rose to a level that they didn't plan for.

Ignoring it doesn't work, making it Illegal does.

When reality doesn't fit the narrative make reality illegal, it's the way of the Reichwing.

Don't be trying to force that Sharia law shit onto these geniuses.

The islands will end up along the former shoreline due to the difference in shelf height.
