Manchester City Council have lowered the speed limit on the Mancunian Way to 30mph. Or at least they say they have - but creating a 30 limit on a motorway is, legally, almost impossible. So what is the speed limit now? #manchester www.roads.org.uk/blog/schrodi...

Today it's the UK's busiest motorway, but its designers had no idea the monster they were creating. How did we end up with the western side of the M25? Discover its origins in the difficult history of the North Orbital Road. #m25 www.roads.org.uk/ringways/rin...

Blimey, that’s a monster!

They're meant to keep urban roads moving, but do you know when you're allowed to enter the yellow markings and when to keep clear? Our guide unpacks the box to answer your questions. www.roads.org.uk/blog/think-i...

Been making these not completely finished but what do you think @rantyhighwayman.bsky.social @showmeasign.online

In 1971 the M602 Eccles Bypass was pushed through the suburbs of Greater Manchester, and its builders were delighted with their work. To celebrate they published a book full of praise and fascinating archive pictures of an urban motorway under construction. #m602 www.roads.org.uk/opening-book...

Road geeks love their jargon, but if you're new to the community you might get lost among the references to D4H, D3M and WS2. Not to worry - we can get you up to speed with our guide to these abbreviations. www.roads.org.uk/abbreviations

We think road numbers are beautiful. Not everyone agrees, but we defy you not to be amazed by this incredbile visualisation of all Great Britain's classified roads. #roadnumbers www.roads.org.uk/blog/colouri...

All roundabouts are the same: you give way to the right when you join. But it wasn't always so. In February 1960 Middlesbrough was the first place to try a new priority to the right rule. The queues vanished immediately, and the new rule stuck. #middlesbrough www.roads.org.uk/articles/rou...

Not all motorways have a hard shoulder, and some have even had theirs removed. But fifty years ago engineers were worried we'd need more of them, not less. Whatever happened to the idea of the second hard shoulder? www.roads.org.uk/blog/rise-an...

Today we take electronic signals on motorways for granted, but the first ones were big, bulky and basic, telling drivers on the M5 to watch out for Skid Risk, Accident and Fog. Do you remember them? #m5 www.roads.org.uk/blog/skid-ri...

We take decent road signs for granted, but there was a time when there was no system of signs fit for the motor age. In 1919 one man set out to create one - and it was years ahead of its time. www.roads.org.uk/articles/cle...

These amazing pictures show the M40 under construction near High Wycombe - and one motorist who didn't look out for the signs when passing through the roadworks. They were sent to us a few years ago by Robert Plato. For more old photos, see our picture gallery: www.roads.org.uk/photo/old-mo...

It's a long way from St Paul's Cathedral to the windswept west coast of Wales, but the A40 covers the miles to unite them. Join us for a trip from end to end, taking in picturesque towns, dramatic landscapes and more than one traffic jam. www.roads.org.uk/blog/out-lon...

Building an urban motorway is fiendishly difficult. But in 1972 London came unbelievably close to building half of one. The West Cross Route was literally half a motorway - were its designers the full ticket? #kensington #shepherdsbush www.roads.org.uk/ringways/rin...

No room for all the cars clogging up your city? No problem. One man thought he had the solution: tunnels. Tunnels for motorways, and tunnels for car parks, making a whole underground network. But his massive Underway system for London was never built. #london #tunnel www.roads.org.uk/articles/und...

It was one of the most hated things ever to appear on the UK's roads. Do you remember the notorious M4 Bus Lane? #m4 #london

It's the short urban road with more than one junction that is totally unique in the UK. Belfast simply wouldn't work without the brutal and brilliant A12 Westlink. #belfast www.roads.org.uk/motorway/a12...

Today you can drive your car underneath one of London's Royal Parks. You can even drive through some of them too. But in the sixties a motorway was built on Hyde Park and you can drive that too. Which one? www.roads.org.uk/blog/hyde-an...

It's the bypass that went through the middle of a town. Bingley, hemmed in by steep hills, had its relief road pushed through the town centre in the early 2000s. We've got a whole gallery of pictures documenting this unusual project: www.roads.org.uk/photo/bingle...

In the UK we're not used to natural forces sweeping away our roads. But in Derbyshire Mam Tor was determined to claim the A625, and eventually engineers had to concede that it couldn't be saved. Join us for a tour of the road that slid away. #castleton #mamtor www.roads.org.uk/blog/road-sl...

In the 60s an elevated motorway tore up West London and the notorious Westway became the stuff of legend. Planners wanted to do the same in the east - would the Eastern Avenue Extension have been just as bad or did they have something else in mind? #hackney www.roads.org.uk/ringways/sec...

Motorways are blue and major A-roads are green. But Devon has other ideas - signs with brown borders, and blue arrows, and sometimes no borders at all. It might not be obvious but Devon's colourful signs can help you avoid getting stuck in a hedge. #devon www.roads.org.uk/blog/devon-h...

How do you build a motorway? Engineers working on the final section of the M65 documented their progress with hundreds of aerial photographs, taken back when you needed an aeroplane to do it, and their pictures provide the answer in full colour. #preston www.roads.org.uk/m65-construc...

From a 1969 film on Irish Plantation towns; a screenshot of Portlaoise with a fine old style Irish traffic direction sign. #ireland @showmeasign.online @roads.org.uk @sabre-roads.org.uk

Just published, another video from our Retro Collection: this time a grand tour around Basingstoke back in early 2008. With flyovers, concrete shopping centres and plenty of roundabouts, it's the full 60s New Town experience. #basingstoke youtu.be/086EA5szE2o

Linking the M27 to Southampton's docks, the M271 is a good road with a bad junction - it's one of two UK motorways that stops halfway along to negotiate a roundabout. #southampton www.roads.org.uk/motorway/m271

The M65 is starting to show its age a bit now. It'll be 28 years since J1a-6 opened this time around. Yikes.

In the early 70s a temporary bridge appeared in West London. But you have to be careful building temporary bridges - if they're too good they become permanent. Join us for a tour of the Meccano flyover that beat the odds to reach its 6th decade. #chiswick www.roads.org.uk/photo/hogart...

Can you imagine Brixton rebuilt in gleaming high rise towers and traversed by a huge motorway in the sky? It was meant to happen. Take a tour of the scarcely believable plans for the South Cross Route motorway. #brixton www.roads.org.uk/ringways/rin...

It's nearing completion now, but will Wisley Interchange be better when it's done? Join us for a deep dive into the reconstruction of M25 J10 to see how much better it will get - and how much better it could have been. #surrey #wisley www.roads.org.uk/blog/we-need...

Central Bradford and Church Bank in 1966 with the HQ of the once mighty Bradford Dyers Association amidst a changing landscape that's changed again. Lots of street lighting & road sign action. @showmeasign.online @sabre-roads.org.uk @lccmunicipal.bsky.social @roads.org.uk (found photo: likey T&A)

Have you ever been to Ilford? And if you have, did you manage to leave, or did the North Circular's Ilford Interchange leave you circling in bewilderment under a mass of flyovers? The meeting of A406 and A118 is in our Bad Junctions list, and for good reason. #ilford www.roads.org.uk/badjunctions...

It's only a mile long and almost entirely at sea. Have you ever driven the M5? No, not *that* M5. The one in Northern Ireland! www.roads.org.uk/motorway/m5-ni

What does "dual carriageway" mean? A lot of drivers would get the answer wrong. We go in search of the right answer, via Birmingham and a small village in rural Wales. #dualcarriageway www.roads.org.uk/blog/what-ma...

It branded itself the Motorway City of the Seventies, but Leeds was still building motorways in its heart in the 90s. Join us for a look at the huge, easily-overlooked and surprisingly new interchange at the heart of the city, M621 J3. #leeds www.roads.org.uk/photo/juncti...

A couple of years ago, a council in Lincolnshire decided to slice an already small motorway in two and give half of it a new number. We still don't really know why. There are only questions, and no answers, for the weird new A1077(M). #scunthorpe www.roads.org.uk/blog/surpris...

How do you draw attention to something you see every day? Westminster have an idea to make zebra crossings stand out… but whether it works or not is in the eye of the beholder. #london

Roads strike out from London in all directions, but the streets of the City rarely seem to have much in common with the farthest reaches of the UK. We took a ride along the A40 - all of it, from St Paul's to the coast of Wales - to see what there was to see. www.roads.org.uk/blog/out-lon...

Speed limits divide opinion like nothing else. How did we end up with the limits we've got and who decides to change them? We take a step back and sort the truth from the emotion in our extended article. www.roads.org.uk/articles/limit

It was the UK's last major motorway project, a new link from London to Birmingham. Revisit the optimism (and the slightly naive greenwashing) of 1991's grand opening with the M40's commemorative booklet. www.roads.org.uk/opening-book...

Most of us never even think about the street outside our home, but what if you had to maintain it yourself? If you live on an "unadopted" road that's exactly what you have to do, and there's more of them than you think. www.roads.org.uk/blog/adoption

It's 1964 & the official guide to Droitwich "The Brine Spa" is determined to show how 'up-to-date' the town is with this splendid photo of a road sign for the new M5 motorway junction with the A38 at Rashwood. #roads #signs @showmeasign.online @roads.org.uk @sabre-roads.org.uk

Some roads are planned and built, others are planned and cancelled. This one has been planned, cancelled and revived so many times it might hold a world record. Meet the Western Orbital, the West Midlands' zombie motorway. www.roads.org.uk/blog/zombie-...

The UK's road signs use symbols to communicate information - including four kinds of arrow, two kinds of bus and two different ferries. Do you know what they all mean? Make sense of the silhouettes with our handy guide. www.roads.org.uk/road-signs/r...

They should be a secret, but every so often someone puts up a sign that gives the game away. Welcome to our collection of C-road signs - little reminders of a world of road numbers you're not meant to see. www.roads.org.uk/photo/c-roads #secret #roadnumbers

It often makes waves in the local papers when a set of traffic lights appear on a motorway sliproad. Back in 2017 it made the front page of the Times... but hang on, didn't we have motorway traffic lights already? www.roads.org.uk/blog/traffic...

Some people hate it, others are terrified of it. London's North Circular isn't many people's favourite road, but we can at least help with our strip-map of the route, straightening out its tangled and congested junctions one by one. #london www.roads.org.uk/motorway/a406

And to think - it should have had "one on top"! From the town's 1973 official guide. @abfixby.bsky.social

Halifax is home to one of the UK's most audacious urban roads, Burdock Way. Two soaring viaducts carry it high above a steep-sided valley and a deep trench brings it around the town centre. How did a small town come to have such an enormous road? #halifax www.roads.org.uk/articles/bur...
