‘Great progress’ with Chiltern tunnel
BY late November, 19 of the 38 emergency cross-passages, linking the northbound and southbound bores of HS2’s 10-mile tunnel under the Chilterns, had been completed.
“We’re making great progress on the Chiltern tunnel, with approaching nine out of the 10 miles complete, and our crosspassage teams are catchingup fast,” said HS2 Ltd project manager Aaron Harrison.
