TUNNEL TO BE LIT.

WELLINGTON UNDERTAKING. WORK AT MOUNT VICTORIA. As there will be none too mack room to spare with two lines of traffic operating in the new Mount Victoria tunnel, Wellington, it is intended to light it well enough to obviate drivers of motor vehicles switching on their own headlamps when making the passage and so creating glare trouble. Driving out of bright sunshine into a poorly-lighted tunnel would cause every driver at once to switch on hit lamps as a safety precaution; while driving out of darkness into a tunnel so lighted might Tiave the opposite effect upon a driver. It is the contrast in the intensity of light which makes the difference. On that account the new tunnel may have to be more brilliantly lighted by day than during the wght. This matter is among those claiming the attention of the officers of the city engineer's department at the present time. It will call for a good deal of adjustment as to the number of lamps and their power before the tunnel lighting is finally decided upon. y = The work of flooring the tunnel in concrete, with provision for the laying rf tramway tracks later, will be put in hand this month. The task of installing the electric fans which are to control the ingress of fresh air and the egress of fool air, by way of the two ventilating .shafts, is now in hand, so that as soon as th» flooring is down the tunnel should be made available for general traffic.
