I was here a few days ago and they had just realigned Port Road and made some changes. A rough sketch of the changes can be found here: https://lensdump.com/i/91XMhF

Black lines are the rough new road alignment. Blue are the new sidewalk alignment.

There are two lanes going in and out of the parking lot (for Hullo users only; the one closer to the terminal is for Helijet only) - both have payment gates, however they do not appear to be in use. 

There are marked crosswalks on the two  sides of the roundabout.

I hope someone with better mapping skills can make the changes and/or find better representations of them. It looks like some (incomplete) changes have been made on Google.
