Missing link in the M50

Madam, - In light of the suspension of the work on the Carrickmines interchange of the M50, I presume the relevant authorities will obtain an agreement from the conservationists that the vast roadworks to be left dormant will not be treated as of "archaeological significance" when the time comes for resumption. - Yours, etc.,
