M6 Birmingham Box Phase 3: Smart Motorway
Part of our programme of improvements (value >10m)
In early March, we completed and opened the first section of the improvement scheme from junction 6 to junction 8, enabling the use of the hard shoulder on this stretch during peak times.
In late March we commenced hardshoulder running trials between junction 5 and junction 6 which were complete by mid-April. The scheme is now fully operational and the hardshoulder between junction 5 and junction 6 will also be opened to traffic at peak times.
You can read the full press release for the operational launch.
There are still some additional maintenance works to be completed and these will continue during night time closures until June. The activities that will continue during these night-time closures are mainly replacement of bridge joints.Installation of road markings.
Details of full carriageway closures and diversions planned for April 2014 can be viewed under Journey Impact.
Removal of traffic management
The traffic management between junction 5 and junction 6 has now been removed but night time traffic management will continue where necessary for bridge joint and road marking works.
The free recovery service on the M6 between junction 8 and junction 5 and on the adjoining M5 links has finished following removal of the traffic management.
Variable speed limits
Variable speed limits are now in operation on the M6 between junction 8 and junction 5 as well as the previously completed adjacent schemes. These enforceable variable speed limits are indicated on the overhead signs above each lane in a red ring and are introduced to help ease congestion during busy periods or if an incident occurs.
To find out about the various features of a smart motorway – including how the variable speed system works – visit our Smart Motorways homepage.
What is happening?
We propose to improve the M6 by making it a "smart motorway" (previously known as managed motorways) between junctions 5 and 8, including M5 link roads. smart motorways help relieve congestion by using technology to vary speed limits. They also allow the hard shoulder to be used as a running lane at peak times to create additional capacity. They deliver these benefits at a significantly lower cost than conventional motorway widening and with less impact on the environment during construction. Find out more about Smart Motorways
When and where is this happening?
Work began in April 2012 and we are planning on opening the scheme to traffic in the first quarter (between April and June) of financial year 2014/15. The Birmingham Box Phase 3 Smart Motorway scheme is the link between junction 5 at Castle Bromwich and junction 8 M6/M5 interchange, serving Walsall, Birmingham and Sutton Coldfield.
Why is this happening and what will it cost?
This work is needed as the route currently suffers from:
- heavy congestion
- unpredictable journey times
- higher than average accident rates
Research carried out on the M42 and M6 has proven smart motorways reduce accidents, and improve journey times. Similarly, journey times have improved between the M40 junction 16, near Lapworth, and M6 junction 5, near Birmingham, since the introduction of two sections of hard shoulder running. Evidence also shows that roadusers say hard shoulder running has improved these sections of the ‘Birmingham Box’ motorways. Road users reported that when smart motorways are in operation there is an average daily saving of about 2 minutes per vehicle for a return journey in peak periods.
The estimated outturn cost for this scheme is £115 million.
How will the scheme be carried out?
A number of cameras, information signs and signals on gantries will be installed as part of the improvement scheme. Some of the existing vegetation within the highway boundary will need to be removed to make space for the new infrastructure. To comply with the Wildlife and Countryside Act 1981, any works which could possibly affect bird nesting sites must be done outside of the breeding season.
The breeding season is March to August inclusive so removal of the existing vegetation was carried out in January and February 2012. Replacement planting will be provided, where possible, around the new infrastructure.
Average speed cameras will be used through the length of the works for the safety of both the road user (motorists) and also, the workforce. Also, temporary CCTV cameras will be installed to monitor for broken down vehicles and other incidents. These were installed in March 2012.
The main works are planned to be done Monday to Friday during normal working hours. However, there will be a significant amount of work done overnight including during weekend periods. During the day, the working space is limited and therefore, not all operations can be done safely. At night, when traffic flows are considerably lighter, lanes can be temporarily closed without causing huge queues on the motorway and the surrounding roads.
Night time working will be needed throughout the construction period for works such as; temporary safety fencing, temporary road markings, resurfacing, cutting MIDAS loops, erection of new gantries, fitting signs and signals to gantries and erection of lighting and CCTV columns. We will endeavour to do all works, whether during the day or at night, with the minimal amount of disruption and disturbance.
If we are planning to carry out works overnight near to people’s homes, we will communicate with them in advance. Also, we will operate a resident’s information line to help in answering questions and providing updates.
The Appraisal Summary Table, summarising the key consequences relating to the environmental, economic and social impacts of this project, has been produced and is available to be viewed under Publications.
What are the benefits?
This project will relieve congestion and smooth the flow of the traffic, improving safety and journey times. These benefits will also support economic development in the region.
We already have evidence of the benefits that a smart motorway scheme can bring. The first smart motorway scheme opened to traffic on the M42 motorway in 2006. Recent analysis of the data gathered since opening has found that journey time reliability improved by 22 per cent and reduced emissions by up to 10 per cent due to traffic flowing more smoothly.
In addition, personal injury accidents have reduced by more than half (55.7%) since hard shoulder running was introduced. There was also an overall reduction in the severity of accidents with zero fatalities and fewer seriously injured.

How will you manage traffic?
Hard shoulder closures, narrower lanes and safety barriers are in place so we can carry out our works safely while maintaining three lanes in both directions. We have implemented a 50mph speed restriction for the safety of drivers and our roadworkers. This may seem frustrating, but driving through half a mile of roadworks at 50mph takes just ten seconds more than at 70mph, while greatly increasing safety. Some of our works, such as gantry installation and removal works cannot be undertaken safely with traffic using the motorway and will require closures. We have scheduled these to take place overnight on weekends, when traffic flows are lighter, to keep disruption to the travelling public to a minimum.
Will there be diversions?
Clearly signed diversion routes will be in place during the overnight road closures.

What happens next
The construction phase commenced on 9 January 2012. Our construction programme has been carefully planned to minimise disruption to road users. Three lanes of the M6 will be kept open in each direction during peak times throughout construction. Lane closures and full carriageway closures will be required, but these will only be at times of reduced traffic flow or at night time.
Details of scheduled closures and diversion routes can be viewed under Journey Impact.
Narrow lane running and speed resictions to keep everyone safe
- There will be 3 narrow lanes in each direction for the duration of the works on site
- An average speed limit of 50mph will be enforced throughout the roadworks for your safety as a motorist and for the safety of our workforce
- During the construction period, CCTV cameras will be installed on the motorway to support the management of incidents
- The CCTV team will promptly identify incidents and notify our vehicle recovery teams to assist stranded motorists
- A free vehicle recovery service will be provided within the road works
- We will provide facilities for stranded motorists where they can make arrangements to continue their onward journeys
The majority of works for a smart motorway scheme take place in the highway verges and on the hard shoulder. In order to carry out these works safely we will be required to close the hard shoulder.
We will be operating a free vehicle recovery service in the event that anyone breaks down and cannot make it to a safe location. The entire length of our works is covered by CCTV cameras which are monitored by a dedicated team in our control room.
In the event of a breakdown the stranded vehicle can be identified quickly and the free vehicle recovery service dispatched to take motorists and their vehicle to a safe location.
Carillion are our contractors for these works. Their stakeholder management team will be available throughout the construction process to answer any queries you may have about the project. They can be contacted at: BB3MM@carillionplc.com and on tel: 0121 332 2200 (Monday to Friday 8am to 5pm).
