The M6 motorway is the longest motorway in the United Kingdom. It is in England and is just over 230 miles (370 km) long. It starts at Junction 19 of the M1 and the western end of the A14 at the Catthorpe Interchange, near Rugby. It goes north-west.
The M6 is very important for travel in the United Kingdom. It is part of a major route running north–south between London and Glasgow. It also helps people travel east–west between the Midlands and ports on the east coast. Some parts of the M6 have been updated to become smart motorways. This makes travel safer and smoother for drivers.
The M6 motorway is the longest motorway in the United Kingdom. It runs for just over 230 miles (370 km) from the Midlands to the border with Scotland, located entirely within England. It begins at Junction 19 of the M1 and the western end of the A14 at the Catthorpe Interchange, near Rugby.
The first section of the motorway, and the first motorway in the country, was the Preston By-pass. It was built by Tarmac Construction and opened by the Prime MinisterHarold Macmillan on 5 December 1958. The motorway was completed in sections over many years. By 1965, sections from Stafford to Preston and Preston to Lancaster were finished. In 1970, the northernmost part of the motorway opened, reaching toward the Scottish border. By 1971, the entire route was completed, stretching from the junction with the M1 motorway at Rugby to the A38 road near Birmingham.

One famous part of the M6 is Junction 6 in Birmingham, known as Spaghetti Junction because of its complex, curvy design. The section of the M6 that goes over Shap Fell in Cumbria is one of the highest points on any motorway in the UK.
Operational
In July 1972, plans were announced to add lighting to 86 miles (138 km) of UK motorway, including parts of the M6. In March 2006, a 6-mile (9.7 km) extension of the M6 opened, connecting it to the Anglo-Scottish border at Gretna. This extension completed an uninterrupted motorway route from near Dunblane in the north to London in the south.
The M6 Toll, Britain’s first toll motorway, opened in December 2003 to help reduce traffic congestion near Birmingham and Walsall. Despite high toll prices, traffic levels on the M6 did not decrease as much as expected.
In October 2007, two busy sections of the M6 were upgraded to allow the hard shoulder to be used as a normal running lane during busy times. This helped improve traffic flow on the motorway. In April 2021, the M6 gained its first new motorway service station in thirteen years, located off Junction 1 at Rugby. The facility includes a large electric vehicle charging area.
Current developments
Work began in 2020 to rebuild bridges above the motorway at junction 10. Traffic can get very busy there sometimes. This project was planned to finish in 2024 and cost about £78,000,000.
In March 2022, more work started to improve the Dynamic Hard Shoulder smart motorway between junctions 4 and 10A. This added new safety features like a stronger central barrier and extra spaces for emergencies. There is no set end date for this project yet.
Work also started in early 2021 to update the M6 motorway from junction J21A to J26. This project cost between £100 million and £250 million. It was first planned to finish in 2023 but was completed in late 2024.
Junctions
Data from driver location signs shows how far each junction is and which side of the road you are on. If a junction is very long and we know where it starts and ends, both distances are shown.

Legislation
Before a motorway can be built in England, a special rule called a statutory instrument must be published. This rule shows the path of the road. The dates on these rules show when the rule was published, not when the road was built. Here are some rules for the M6 motorway:
Statutory Instrument 1987 No. 252: County Council of West Midlands (M6 Motorway Junction 10) (Connecting Road) Scheme 1985 Confirmation Instrument 1987
Statutory Instrument 1990 No. 2659: M6 Motorway: Widening between Junctions 20 and 21A (Thelwall Viaduct) and Connecting Roads Scheme 1990
Statutory Instrument 1991 No. 1873: M6 Motorway (Widening and Improvements Between Junctions 30 and 32) and Connecting Roads Scheme 1991
Statutory Instrument 1993 No. 1370: Lancashire County Council (Proposed Connecting Roads to M6 Motorway at Haighton) Special Roads Scheme 1992 Confirmation Instrument 1993
