WikiPortallus: M1 motorway.html

The M1 is a major north – south motorway in England primarily connecting London to Leeds, where it joins the A1(M) near Aberford. While the M1 is considered to be the first inter-urban motorway to be completed in the United Kingdom,¹ the first road to be built to motorway standard in the country was the Preston Bypass, which later became part of the M6.²

The motorway is 193 miles (311 km) long and was constructed in four phases; the majority of the motorway was opened in 1959 and between 1965 and 1968. The two ends of the motorway were extended later; the southern end in 1977 and the northern end in 1999. It forms part of the unsigned European route E13.

History

First section, 1959

The first section of the motorway opened between junction 5 (Watford) and junction 18 (Crick/Rugby) on 2 November 1959 together with the motorway's two spurs, the M10 (from junction 7 to south of St Albans originally connecting to the A1) and the M45 (from junction 17 to the A45 and Coventry).

The M1 was officially inaugurated from Slip End (close to Luton), this was celebrated by a large concrete slab³ on the bridge next to the village with inscription "London-Yorkshire Motorway, This slab was sealed by the Rt Hon Harold Watkinson M.P. Minister of transport inauguration day, 24th March 1958".

This section of the M1 broadly follows the route of the A5 north-west. It started at the Watford Bypass (A41), which runs south-east to meet the A1 at Apex corner, and ended on the A5 at Crick. The M10 spur motorway connected the M1 to the North Orbital Road (A405/A414, a precursor of the M25) where it also meet the A5 (now renumbered here as the A5183) and, two miles to the east via the A414, to the A6 (also renumbered as the A1081).

Although the whole of first section opened in 1959 it was built in two parts with the northern part (junctions 10 to 18) being built by John Laing¹ and the southern part (the St Albans Bypass) being built by Tarmac Construction.⁴

There has never been a Junction 3 between Junctions 2 and 4. The number was assigned to a connecting spur north-east to the A1 at the present location of the Scratchwood Service area.

Rugby to Leeds, 1965 to 1968

The continuation of the motorway from junction 18 towards Yorkshire was carried out as a series of extensions between 1965 and 1968. Diverging from the A5, the motorway takes a more northerly route through the East Midlands, via Leicester, Loughborough, Nottingham to Sheffield where the M18 splits from the M1 at junction 32 to head to Doncaster.

Originally, the M1 was planned to end at Doncaster; however, it was decided to make what was going to be the "Leeds and Sheffield Spur", the primary route with the 11-mile (18 km) section to the A1(M) south of Doncaster given a separate motorway number.

From junction 32, the motorway passes between Sheffield and Rotherham, towards Barnsley then heads towards Wakefield and reaches the original end of the motorway at junction 44 to the east of Leeds. There were plans to route the M1 from just south of junction 42 where it interchanges with the M62, round the west of Leeds to the A1 at Dishforth; however the existing route to the east of Leeds was selected. With the M62 and M621, the M1 forms a ring of motorways around the south of Leeds.

Leeds South Eastern Urban Motorway, 1972

In 1972 an extension of the M1 was opened into central Leeds as the Leeds South Eastern Motorway where it met the Leeds South Western Motorway (M621) coming north-east from the M62 at junction 3.

Leeds to Hook Moor, 1999

Between 1996 and 1999 the M1 section north of the M62 underwent a major reconstruction and extension to take the M1 on a new route to the A1(M) at Aberford. The new road involved the construction of a series of new junctions, bridges and viaducts to the east of Leeds. When the new section of M1 was completed and opened in 1999, the Leeds South Eastern Motorway section of the M1 was redesignated as the M621 and the junctions were given new numbers (M621 junctions 4 to 7).

London extensions, 1966, 1967 and 1977

The M1 was extended south from its original starting point at junction 5 towards London in three stages. The first stage, opened in 1966, took the motorway south-east, parallel to the A41 to meet the A5 at junction 4 south of Elstree. The second phase continued east to Scratchwood (where the London Gateway Service Area occupies the location of the missing junction 3 from where an unbuilt spur would have connected to the A1 at Stirling Corner), then south to run alongside the Midland Main Line towards Hendon where it meets the A1 again at junction 2 via a tightly curved flyover section. These flyovers connecting from the A1 were originally both for northbound traffic; the left one as the onramp to the M1, the right one going over the A1/A41 junction beneath to rejoin the A1 northbound.

The current junction 2 is about 650 yds (600 m) south of the original junction. Southbound traffic originally left the motorway via a slip road which passed under the A41/A1 Mill Hill Bypass and looped round to join it at Fiveways Interchange. This slip road is still in place and maintained, though not accessible to traffic. The northbound slip road from the A1 is now partially used as the entrance way to a business park but no longer reaches the northbound carriageway as it is cut off by the motorway continuing south.

The final section of the M1 was opened to junction 1 at Staples Corner in 1977. There the motorway meets the North Circular Road (A406) at a grade separated junction and roundabout. Plans made in the 1960s would have seen the motorway continue through the junction on an elevated roadway to end at West Hampstead where it would have met the North Cross Route, the northern section of the London Motorway Box, a proposed ring of urban motorway around the central area. The layout of the Staples Corner junction was originally built in accordance with these plans although most of the London Ringways Plan had been cancelled by 1973.

Improvements underway

Widening from Junction 6a to 10

Works to widen the M1, reducing congestion and improving both safety and journey time reliability, commenced mid-March 2006 and are expected to be completed by December 2008.⁵

Widening from Junction 25 to 28

Work to widen the 15-mile stretch of motorway between Nottingham and Mansfield to four lanes each way began in January 2008 and is scheduled for completion in 2010.⁶

Junction 29A

Widening from Junction 31 to 32

Work to widen this short 1-mile stretch near Sheffield to four lanes each way was completed in January 2008.⁷

Proposed improvements

Junction 19

Widening from Junction 10 to 13

The proposed scheme originally comprised of widening approximately 15 miles (24 km) of the M1 motorway between Junction 10, south of Luton, and Junction 13 where it joins with the A421, from 3 to 4 lane carriageway.¹⁰ The scheme also includes modification to junctions 11, 12 and 13 and the removal of bridges crossing the motorway that are considered of historical architectural value.¹¹ However at the pre-inquiry meeting on 29 November 2007 the Highways Agency announced an estimated 4 month delay to the planned Public Inquiry due to further traffic modeling work being undertaken.¹² Since this time no further timetable for the progression of the scheme has been given and hard shoulder running is now being considered as an alternative¹⁰ In 2004 an estimated cost of the scheme was given at £382 million¹³ but since then an increase in the estimated cost has contributed towards the reappraisal of the scheme.¹⁰

Other widening proposals

There are plans to widen virtually the entire route of the M1 from Leicester through to Leeds.¹⁴ The National Audit Office was called in in May 2007 to investigate why the price of the project has risen from £3.7bn to £5.1bn (this includes the section from the M25 to Luton, junctions 6a - 10, which is already under construction.¹⁵

Notable events

On 6 September 1997 large sections of the northbound carriageway were closed between London and Althorp, Northamptonshire to allow for the funeral procession of Diana, Princess of Wales. In an unprecedented event, police allowed pedestrians onto the normally busy northbound carriageway almost the entire length of the route to pay their respects.

In 2002, a section of the M1 near Milton Keynes was cleared using mobile police roadblocks to allow for filming of the movie 28 Days Later.

An 18-mile (29 km) stretch of the motorway was closed entirely on the morning of 11 December 2005 following a massive explosion and fire at the Buncefield Oil Depot, which is situated less than half a mile from the M1.

On the morning of 24 August 2008 the Tinsley Viaduct and surrounding motorway was closed to allow safe demolition of the Tinsley cooling towers. The demolition occurred at 0300 BST,¹⁶ the M1 remaining closed for much of the day until the stability of the viaduct was confirmed.
