Question About New Development Center

Sorry if this has already been asked, but back when the plans were announced they mentioned the cost increased some because of the need to build a tunnel from the center to the game day dugout. This feels like a ridiculous question to ask, but I haven’t seen it mentioned anywhere. Will the team be moving to the first base dugout, or is this going to be one long tunnel?

Thanks in advance.

Here’s an article on the cost from July:
