Madam, - I feel the most telling phrase in Liam Reid's article on the N11 through the Glen of the Downs (Weekend Review, October 18th) was that it will be "one of the most environmentally sensitive ever built in Europe".

Madam, - What is the logic behind upgrading six kilometres of single carriageway to dual carriageway (motorway standard) at enormous expense, time and inconvenience , and then putting a 40 m.p.h. limit on it - 20 m.p.h. lower than the original carriageway. Have I missed something? - Yours, etc.,
