The M4, originally the London-South Wales Motorway, is a motorway in the United Kingdom running from west London to southwest Wales. The English section to the Severn Bridge was constructed between 1961 and 1971; the Welsh element was largely complete by 1980, though a non-motorway section around Briton Ferry bridge remained until 1993. On the opening of the Second Severn Crossing in 1996, the M4 was rerouted over it.
The M40 motorway links London, Oxford, and Birmingham in England, a distance of approximately 89 miles (143 km).
The M5 is a motorway in England linking the Midlands with the South West. It runs from junction 8 of the M6 at West Bromwich near Birmingham to Exeter in Devon. Heading south-west, the M5 runs east of West Bromwich and west of Birmingham through Sandwell Valley. It continues past Bromsgrove, Droitwich Spa, Worcester, Tewkesbury, Cheltenham, Gloucester, Bristol, Portishead, Clevedon, Weston-super-Mare, Bridgwater, Taunton, Tiverton, Cullompton terminating at junction 31 for Exeter.
The A34 is a major road in England. It runs from the A33 and M3 at Winchester in Hampshire, to the A6 and A6042 in Salford, close to Manchester City Centre. It forms a large part of the major trunk route from Southampton, via Oxford, to Birmingham, The Potteries and Manchester. For most of its length, it forms part of the former Winchester–Preston Trunk Road. Improvements to the section of road forming the Newbury Bypass around Newbury were the scene of significant direct action environmental protests in the 1990s. It is 151 miles (243 km) long.
The M32 is a 4.4-mile-long (7.1 km) motorway in South Gloucestershire and Bristol, England. It provides a link from the M4, a major motorway linking London and South Wales, to Bristol city centre and is maintained by National Highways, the national roads body.
The M48 is a 13-mile-long (21 km) motorway in Great Britain, which crosses the Severn near Chepstow, Monmouthshire, linking England with Wales via the Severn Bridge. This road used to be the M4, and as a result is anomalously numbered: as it lies to the north of the M4 and to the west of the M5, it is in the Motorway Zone 5. The M4, M48 and the A48(M) motorway are the only motorways in Wales.
The M49 is a motorway in England that links the M4 (J22) with the M5 (J18A). The southern end is on the outskirts of Avonmouth and the northern end is immediately to the east of the Prince of Wales Bridge which was constructed at the same time 1996. It is 5 miles (8 km) long and unique in that it is only accessible from other motorways.
The N4 road is a national primary road in Ireland, running from Dublin to the northwest of Ireland and Sligo town. The M6 to Galway diverges from this route after Kinnegad, while the N5 to Westport diverges at Longford town. Most sections of the N4 that are motorway-standard are designated the M4 motorway.
Chieveley is a village and large civil parish centred 3.5 miles (5.6 km) north of Newbury in Berkshire, close to the M4 motorway and A34 road. Chieveley services are within the parish.
The A419 road is a primary route between Chiseldon near Swindon at junction 15 of the M4 with the A346 road, and Whitminster in Gloucestershire, England near the M5 motorway. The A419 is managed and maintained by a private company, Road Management Group, on behalf of the UK Department for Transport.
Moto Hospitality Limited, trading as Moto, is a British service station operator which operates 59 motorway service stations across the United Kingdom. It is currently the UK's largest service area operator.
The A329(M) is a motorway in Berkshire, England. It is 4 miles (6.4 km) long and runs from the west of Bracknell to the north west of Winnersh. It is one of a small number of parts of the motorway system in England that are managed by the local highway authority, in this case Wokingham Borough Council, rather than National Highways.
The Almondsbury Interchange in South Gloucestershire, is one of the United Kingdom's largest motorway stack interchanges. The interchange is one of only three four-level stacks in the UK, spanning a range of 1 km by 1 km. It is the interchange for the M5 at junction 15 and M4 at junction 20, and is situated at the northern fringes of Bristol close to the village of Almondsbury, the Aztec West industrial estate, and Bradley Stoke. When it opened in 1966, it was the most complex junction on the British motorway network, a free-flowing interchange on four levels. Since then traffic volumes have increased. At busy periods, the Interchange becomes more difficult to negotiate safely. In an attempt to ease congestion, the Interchange has become part of a smart motorway.
Oare is a small village in the civil parish of Chieveley in the English county of Berkshire.
Snelsmore is a hamlet in Berkshire, England, and part of the civil parish of Chieveley. The settlement lies near to junction 13 of the M4 motorway, and is located approximately 3.5 miles (5.6 km) north of Newbury.
The M6 motorway is a motorway in Ireland, which runs from Dublin to Galway. The M6 extends from its junction with the M4 at Kinnegad all the way west to the outskirts of Galway City, but the Athlone bypass and the approach to Galway city - while of dual carriageway standard - have not been designated motorway and are still signed as N6. The motorway was officially completed and opened to traffic on 18 December 2009, and was the first city-to-city direct major inter-urban route to be completed in Ireland. The M6 and M4, which form the Galway–Dublin route, consist of a grade-separated 2+2 dual carriageway road with a top speed limit of 120 km/h. At approximately 144 km (90 mi), the M6 is the third longest motorway in the state and will be 159 km.
In Ireland, the highest category of road is a motorway, indicated by the prefix M followed by a one- or two-digit number. The motorway network consists entirely of motorway-grade dual carriageways and is largely focused upon Dublin. There are also several three-lane motorways, while Ireland's busiest road, the M50, incorporates four-lane, five-lane, and six-lane stretches.
A smart motorway, also known in Scotland as an intelligent transport system, is a section of motorway in the United Kingdom that employs active traffic management (ATM) techniques to increase capacity through the use of MIDAS technology including variable speed limits and occasionally hard shoulder running and ramp metering at busy times. They were developed at the turn of the 21st century as a cost-effective alternative to traditional carriageway widening, with intended benefits ranging from more reliable journey times to lower vehicle emissions. However, despite the risk of a collision occurring between two moving vehicles being found to be decreased, there has been an acknowledged rise in the incidence of collisions involving vehicles where at least one was stationary in the first few years following the widespread removal of the hard shoulder on the country's busiest sections of motorway. Smart motorways garnered intense criticism from politicians, police representatives and motoring organisations, particularly from 2020 onwards, after a surge in near miss incidents and dozens of fatalities were revealed, and as of April 2023, no new smart motorways will be built.
