Where is the actual entrance to Zagreb airport (Zračna luka Franjo Tuđman)?

I am confused about the exact location of the (departures) entrance to the Zagreb airport.

Searching for Google Maps direction to the airport places the destination point somewhere around (45.741151, 16.081114). This is also the part of the map that is shown on their official site when searching for driving directions to the airport and it is also close to the official airport's address, Ulica Rudolfa Fizira 21.

However, the satellite imagery does not show the roads sketched out on the map of this part and the terminal location seems to be somewhere around (45.732079, 16.060357).

I remember that the entrance is overlooking the park seen at these coordinates. I thought that the terminal perhaps moved, having found this piece of news about the new terminal. To add to my confusion, I realized this must have been already built the last time I was at the airport, but the photos do not ring a bell.

I would like to know the precise location to estimate the feasibility of walking to the airport from a nearby hotel. The two points in question are more than 2 km apart according to Google Maps.
