At last, the respective cases case for the Longdendale Bypass & Glossop Spur have been published today. The Highways Agency Statement of Case can be found here and here, and the TMBC Statement of Case here (all links open PDFs).
It should be noticed that these are not 'proofs of evidence' which the HA openly admitted may not be submitted by the deadline. TMBC could also not give a firm commitment to having their evidence ready in time. The deadline is 5th June (3 weeks before the start of the Inquiry) - we await it with baited breath.
