Tunnelled vision


With regard to the report on the Holmesdale Tunnel (NCE 28 September), why on earth would anyone imagine that adding a fourth lane to a British motorway would make any difference to traffic flows.

The average British motorist never drives on the inside lane anyway.

If I were living in one of those blighted rural towns that had lost its bypass to spending cuts, I would be seething at the thought that someone in the Highways Agency could have approved spending £75M on widening a Nimby instigated cut and cover box on the top of a hill on the M25.

For that kind of money it could have eased the misery endured by far more people than those precious few using the M25.

To call it a tunnel is a bit of a joke. If you want to see a real busy tunnel in action go to either Antwerp or Rotterdam where longer structures under major rivers accommodate thousands of heavy trucks every day.

To make matters worse, the Holmsdale designers are even adding more 'tunnel' just to put in some new ventilation.

I would have thought that drilling a few holes in the roof would have been a bit simpler.

It worked for Brunel and all those other railway tunnel engineers.
