I have mentioned this before:
There is a bridge just above the BB. At ONE POINT it was proposed that the battleship be cut into 3 pieces and lifted up above the highway on an overpass where it would sit allowing drivers to drive UNDER the BB as they entered the city coming off the bridge. The cost, naturally, was huge, but the overpass was there anyway (it's where they eventually built the new city hall).
Your thought of squashing the Convention Center brought that memory back to me.
