You could find this map with all the tunnel information through their mobile apps http://www.cedd.gov.hk/eng/mobileapp/index.html You only need to download the HKGeology app and then go to the map page. Once you begin to zoom in to the map, you will notice all of the existing air-raid precaution tunnels are marked with numbers, e.g. N1, N2, N3. So the one across HSBC will be N23 (Network 23). I've added "network 49" to the map myself since the orignal text N49 is so tiny to be seen. Hope this information helps.
Something to watch out for: the HKGeology map uses its own numbering scheme for the tunnel networks, so their list includes the wartime ARP tunnels built by the British but with different numbers, and also includes other, smaller tunnel networks that weren't built as ARP tunnels. eg they show the tunnels opposite from HSBC as "Network 23", but the list of ARP tunnels showed this as ARP network number 1, and ARP network number 23 was down in Aberdeen.
So the tunnel in the map above is "Network 49" in the database that the HKGwology app uses, but not "ARP Network 49" in the list of tunnels built as air raid shelters.
In any case, it's a great tool, so thanks for letting us know about it. I'll post up their outline of the Leighton Hill tunnels next.
I'm glad to learn that you enjoyed the map tool and thanks for your great illustration of the Leighton Hill tunnel network. Thank you also for clarifying the numbering scheme of the actual ARP tunnels so now that I won't get mixed up with those assigned by CEDD. I will certainly revisit the site when the weather gets cooler to find out if the entrance of N49 still exists.

Tunnel map
Hi Freddie,
That's a very interesting map, thanks for posting it.
I don't see the tunnel when I look at the Geoinfo website. Is there some option I have to choose to see it?
Is the "Network 49" shown on the map, or is that text you've added?
Regards, David

The map in the hkgeoloy is very good
Hi there,
The base map of the HKGeology app is very good. If you zoom in you have details down to the house level.
Thanks,

Suggestion
Suggest to delete the reference to "ARP" in the title and replace it with "Tunnel Network 49".
