The M6 motorway is the longest motorway in the United Kingdom. It is entirely within England, stretching over 230 miles (370 km) from the Midlands to the Scottish border. It starts near Rugby and heads north-west.
The M6 passes through many major cities like Coventry, Birmingham, Wolverhampton, Stoke-on-Trent, Preston, Lancaster, and Carlisle. It also runs between Manchester and Liverpool. The motorway ends near Gretna, where it becomes the A74(M), which continues to Glasgow. Some parts of the M6, especially near Birmingham and Cheshire, are very busy. These sections have been updated to become "smart motorways" to help manage traffic.
The M6 includes the Preston By-pass, which was the very first motorway section opened in the UK. This road is a key part of Britain's main north-south motorway network, connecting London and Glasgow. It also helps link the Midlands to ports on the east coast.

Exploring the M6 Route
The M6 motorway begins at Catthorpe near Rugby in central England. It travels north through important cities like Coventry, Birmingham, Stafford, Wolverhampton, and Stoke-on-Trent.
Further north, the M6 connects with other major motorways like the M56 and M62 near Warrington. These links provide access to cities such as Chester, Manchester, and Liverpool. The M6 also meets the M65 south of Preston, which goes to Blackburn and Burnley. North of Preston, it connects with the M55, leading to Blackpool.
The M6 continues past Wigan, Preston, and Lancaster. After these cities, it goes through Cumbria, with some parts running very close to the Lake District. Finally, it passes Carlisle before reaching Gretna and becoming the A74(M) just before the Scottish border.
Building the M6: A Look Back
The first part of the M6, known as the Preston By-pass, was also the first motorway ever opened in the UK. It was built by Tarmac Construction and opened on December 5, 1958, by Prime Minister Harold Macmillan.
In 1959, the Preston By-pass had to close briefly because the road surface was damaged by freezing and thawing water. This taught engineers important lessons about drainage. More sections were built over the years, including the Lancaster by-pass in 1960 and the Stafford by-pass in 1962. By 1965, the main sections connecting Stafford to Preston and Preston to Lancaster were finished.
By 1971, the entire route was complete from the M1 near Rugby to the A38 road north-east of Birmingham. This included the Bromford Viaduct, which is 3.5 miles (5.6 km) long and the longest viaduct in Great Britain.
Famous Junctions and High Points
One of the most famous parts of the M6 is Junction 6 in Birmingham, which opened in May 1972. It is widely known as Spaghetti Junction because of its complex, curvy design.
Another interesting section is over Shap Fell in Cumbria. At Shap Summit, the M6 reaches 1,036 feet (316 meters) above sea level, making it one of the highest points on any UK motorway. Here, the northbound and southbound lanes split apart, and a local road even runs between them.
The M6 was originally planned to replace the old A6 in some areas. When all sections were finally connected, the M6 became an uninterrupted motorway stretching about 230 miles (370 km).

Modern Updates and Changes
In July 1972, the government decided to add lighting to 86 miles (138 km) of UK motorways that were often foggy, including parts of the M6. This project was completed by 1973.
After many years of discussion, a 6-mile (10 km) extension of the M6 was approved in March 2006. This extension connected the M6 from Carlisle to the Scottish border at Gretna, linking it to the existing A74(M). This new section opened on December 5, 2008, exactly 50 years after the Preston By-pass opened. This completed a continuous motorway route from just south of Dunblane in Scotland all the way to Exeter and London in the south of England.
The M6 Toll road, which opened in December 2003, was Britain's first toll motorway. It was built to help reduce traffic jams around Birmingham and Walsall. Before the M6 Toll opened, the M6 in this area carried 180,000 vehicles daily, much more than it was designed for. Even though the M6 Toll was built to ease this, its usage was lower than expected, partly because of the cost.
In October 2007, the government announced that parts of the M6 would be upgraded to "smart motorways". This system allows the hard shoulder (the emergency lane) to be used as a regular lane during busy times. This helps traffic flow better. Sections between junctions 4 and 5 were completed in December 2009, and between junctions 10a and 8 in March 2011. Further upgrades continued, with the section between junctions 5 and 8 finished in October 2014.
More recently, the M6 between junctions 16 and 19 became a smart motorway in March 2019. The section between junctions 13 and 15 was completed in August 2022.
In April 2021, the M6 gained its newest motorway service station at Junction 1 near Rugby. This facility, run by Moto Hospitality, includes the UK's largest electric vehicle charging station.
Current M6 Improvements
The M6 motorway is always being improved to handle more traffic and make journeys safer.
Junction 10 Upgrades
Work began in 2020 to rebuild the bridges at Junction 10 of the M6. This area often experienced heavy traffic jams during busy times. This project, costing £78 million, was completed in 2024.
Smart Motorway Enhancements
In March 2022, work started to upgrade the existing smart motorway sections between Junctions 4 and 10A. These improvements added new safety features, such as a concrete barrier in the middle of the road and new emergency stopping areas. This work is still ongoing.
Junction 21A to 26 Smart Motorway
Work also started in early 2021 to upgrade the M6 from Junction 21A to Junction 26 to the "all lane running" standard of smart motorway. This means the hard shoulder can be used as a regular lane at all times. This project, costing between £100 million and £250 million, was completed in late 2024.
