Checked it out the other night, it's pretty fancy. they repurposed some of the old road layout, but they added a new road to get to the car park ramp and a mini roundabout where the Y junction used to be. there's a bunch of new facilities too like an ev charge station and even some electronic bike lockers. 

two of the bus stops aren't in use right now but the northernmost bus stop has some bus times displayed.  the one next to the tunnel is a train replacement service bus stop.

i've done what i can to get the ball rolling, by mapping out a semi-accurate road, but without any updated satellite images, it's a bit tricky.
i'll leave it up to somebody more experienced to map it out properly when the satellite images eventually get updated, but for now, at least it kinda resembles the new layout.

gonna also leave this note open to raise awareness.

i hope any of this is helpful. :)
no idea what this new bus station is called.
