I have marked the limits of visibility upstream and downstream from No.3.
From tram station one can see 140 feet downstream.
From No.3 upstream one can see 300 feet&downstream 396 feet.
The difference between the downstream visibility from tram station and upstream visibilty from No.3 is 55 feet,
I made these measurements on 29th August.
Width of tunnel is even throughout.
Paving same as in nullah.
Four gratings all open.
