The Project
The M1 is one of the busiest motorways in Britain and is a strategic link between London, the Midlands and the North. The section between Junctions 6A and 10 is approximately 10 miles (17 km) long, stretching from the M25 through to Luton.
The Works
Work to widen the M1 Junctions 6A - 10, commenced mid March 2006 and was carried out on both carriageways to bring it up to a full standard four lane motorway with continuous hard shoulders. This was achieved by widening the following sections:
- Junctions 6A-7 southbound
- Junctions 8-9 northbound and southbound
- Junctions 9-10 southbound
Other works included:
- Construction of new parallel roads between Junctions 7 and 8 to cater for local traffic travelling between Hemel Hempstead and St. Albans.
- Widening or replacement of 11 underbridges on one or both carriageways.
- Replacement of 7 overbridges.
- Extensive public utility diversions, notably the overhead power cables at Junction 10 and near Redbourn.
The motorway was opened for traffic on 19 December 2008 and a ceremony to mark the completion of the widening works on the main carriageway was attended by the Right Honorable Geoff Hoon MP, Secretary of State for Transport on Friday 23 January 2009.
Formal completion of all works - 8 May 2009 with contract handover into maintenance - 22 June 2009.
One Year After Opening study
As part of our ongoing programme of Post Opening Project Evaluation (POPE) this scheme has been reviewed at one year after opening. The study compares the outturn effects of this scheme to the predicted impacts.
