I MUST respond to the numerous misapprehensions in today's letters regarding the recent traffic jam on the A80.

Unlike many of the most vociferous opponents of the so-called Kelvin Valley route for the completion of the M80, who I understand have only moved into the area in very recent years, I am a long-term resident of the area. I lived in Kilsyth as a child over 50 years ago, and moved back into the area 30 years ago, so I think I can fairly claim to a degree of local knowledge.

Frankly, I do not recognise the ''beautiful Kelvin Valley'', so often referred to - at least in reference to the proposed motorway route, part of which consists of former industrial sites, with the remainder either bog or very marginal-quality farmland.

With reference to Mrs Anne Fairley's comments on the A74 upgrade, only a small stretch is in fact on-line, and it is in very open countryside, and not threaded between built-up areas, as would be an on-line upgrade of the A80. A much more valid comparison would be the on-line upgrade of the A1 between Peterborough and Alconbury where, despite carrying considerably less traffic than the A80, delays are the norm.

Regarding Mr Dave Holladay's comments, I am well aware of the existence of the railway, and have been an enthusiastic supporter of the expansion of rail services for over 30 years, and still believe that railways are by far the best means of transport in an urban area or between centres of major population.

Given the rundown of rail services over the last 40 years this is not, however, the case in most of Scotland, and is frankly irrelevant to the A80 situation. There is no way that current or even expanded rail services could cope with the 70,000 daily journeys on the A80, much of which is freight traffic which, failing the existence of a railway siding to every shop, supermarket, and factory in the country, would still have to move by road at some stage of its journey, with consequent transfer costs.

For Mr Holladay's information, despite much local lobbying, there are no rail services from Cumbernauld to Stirling or indeed anywhere to the north or east. As for his comments on the M90, I can only conclude that he has obviously not travelled to Edinburgh on this road between 7 and 9 on any weekday morning.

IT was inevitable, really; one bad traffic jam and the Kelvin Valley is once again a ''wasteland'' ripe for destruction (May 29 and 30).

This priceless piece of countryside should not be discarded so lightly and if you support the view that it should not be destroyed by a motorway, then roadworks, such as those that disrupted the A80 on May 26, fall neatly into a conspiracy theory. They get worse every time the debate hots up and are done to justify the unjustifiable.

Other roads have traffic jams too. I have been in plenty on the A8/M8 this year, including the equally newsworthy one when an electric cable fell across the road - yet no-one responded with a call to plough up the countryside between Harthill and Whitburn. Why is the Kelvin Valley so dispensable?

The Forth and Clyde Canal Society operates a trip boat along the stretch of canal that would be worst affected by a motorway. It is lovely, and those who seek its destruction are welcome to come for a sail - Sunday afternoons throughout the summer season - and see what is at risk. The canal will soon be revitalised by the Millennium Link scheme; it would be perverse to wreck it at the same time.
