A66 Development Consent Order Changes Explained
On 15 April 2026, the Government made the A66 Northern Trans-Pennine Development Consent (Amendment) Order 2026, and it came into force the next day, 16 April. In plain English, this is an update to the legal paperwork behind the already approved A66 upgrade, not a brand-new road scheme. If you read the statutory instrument on legislation.gov.uk, it looks like a wall of route numbers, sheet references and tiny measurement changes. But those details matter. They decide where a path runs, how land can be reached, and what builders are legally allowed to alter.
For big infrastructure projects in England, a development consent order, usually shortened to DCO, is the planning permission and rulebook rolled into one. It can authorise construction, stop up or realign roads, create new access tracks, alter rights of way and set traffic rules. That is why one road project can generate pages of legal text. The A66 Northern Trans-Pennine scheme received its main order in 2024. This 2026 amendment sits on top of that earlier approval. The Secretary of State considered an application made under the Planning Act 2008 and, after publicity and consultation under the 2011 regulations, decided the changes could go ahead.
The phrase non-material change can sound misleading, so it is worth slowing down here. It does not mean unimportant. It means ministers decided the changes were not big enough to reopen the whole planning decision from scratch. **What this means:** the overall A66 project stays in place, but parts of its legal description are being tidied, corrected or adjusted. In this order, that mostly means revised plans, altered route measurements, renamed locations, and updates to the way footpaths, cycle tracks and private access routes are described.
Some of the clearest changes appear in the descriptions of the authorised works. A new work item, Work No. 0102-1D-A, is inserted near the M6 Junction 40 to Kemplay Bank section. It covers extra carriageway works east of the new Kemplay Bank Junction and a new private means of access to an attenuation pond. Elsewhere, wording is changed so that some routes previously labelled as footpaths are now described as cycle tracks, especially in the Penrith to Temple Sowerby section. The order even updates one location reference from Countess Pillar to the former Llama Karma Kafe. That may sound minor, but planning law depends on precise labels. If the map and the legal text do not match, disputes become much more likely.
Most of the amendment is about Scheme 0405, the Temple Sowerby to Appleby stretch. Here, the Government changes dozens of measurements and route descriptions for Priest Lane, Cross Street, Long Marton, several bridleways and several footpaths. Some lengths are shortened, some are extended, some directions are corrected, and some entries are removed altogether. There are also updates to private means of access, including arrangements linked to the new footpath labelled Reference C and access crossing the new A66 by bridge. For landowners, walkers, riders and cyclists, these are not small details. They shape how you get from one side of the scheme to the other, where replacement paths begin and end, and whether a route is for walking only or for cycling too.
The order also adjusts road classification and speed-limit measurements in later schedules. Again, this is the kind of thing most of us skip past, but it is part of how the approved scheme is fixed in law. A difference between 1.2 kilometres and 1.15 kilometres, or between one junction point and another, can change which stretch of road a rule applies to. The explanatory note on legislation.gov.uk also says the undertaker must submit any new, revised or substituted plans to the Secretary of State for certification. That creates an official set of drawings which can be used as evidence if there is a disagreement later. Schedule 10 is replaced with a fresh list of plan sheets, covering works plans, engineering drawings, rights of way and access plans, and traffic regulation plans.
If you are wondering what happens next, the practical answer is fairly unglamorous: the paperwork now matches the updated design more closely, and the certified plans can be inspected at National Highways' offices in Birmingham. For most drivers on 16 April 2026, nothing dramatic changed overnight. For people living along the route, though, this is the sort of legal update that can affect access, crossings and the position of replacement paths. **What this means for you:** this order is a good example of how infrastructure planning really works. The headline decision is only one part of the story. After that come the exact lines on the map, the width of the route, the rights of way that are protected or replaced, and the access arrangements that decide whether a scheme works in everyday life.
