The interchange is at junction 20a of the M6 but due to the closeness of the two junctions much of the work will focus around junction 20 of the motorway about a half a mile north of the interchange itself.
The work is due to start on Saturday 8 September and be completed by Friday 12 October.
During the roadworks, junction 20 will be subject to full overnight closures alongside overnight lane closures on the main southbound carriageway ahead of junction 20a.
LGV drivers in particular are being advised that the overnight slip road closures - between 10pm and 5am each night - will affect access to Lymm Truckstop from the southbound M6 via junction 20.
However, the roundabout with the A50 at the end of the exit slip road will remain open with access to Lymm Truckstop available from the M56, northbound M6 and A50 Cliff Lane at all times.
All traffic wishing to leave the M6 at junction 20 when it is closed overnight will be directed onto the westbound M56 from junction 20a, turning at junction 10 to join the eastbound M56 and leaving at junction 9 for the A50. This will be clearly-signed for drivers.
The overnight slip road and lane closures around junction 20 are needed to adjust lane markings as well as signing on the large overhead gantry which straddles the main carriageway and exit slip road.
The project is designed to make accessing the M56 safer and smoother by providing better road markings and overhead direction signs. The new arrangements will encourage better lane discipline and provide more effective separation between drivers leaving at junction 20a for the M56 or continuing along the M6.
Highways Agency Project Manager Neal Symmons said:
''This project will provide safer and smoother access onto the M56 from the southbound M6 by reducing late lane changes.
''During the work the southbound M6 and access to the M56 from junction 20a will remain open at all times but there will be regular weeknight overnight closures of the exit slip at junction 20 and that will affect late access to Lymm Truckstop.
''We are working hard to keep LGV drivers and the truckstop informed about the project and would like to reassure the haulage community that departure from the truckstop will not be affected while alternative access to the facility - via the A50 local road - will be available at all times.''
Notes to Editors
1. The Highways Agency is an executive agency of the Department for Transport. We manage, maintain and improve England’s motorways and other strategic roads on behalf of the Secretary of State.
2. In the North West, day-to-day running and maintenance of the motorway network and other strategic roads is managed by two Area Performance Teams – Area Ten covering Cheshire, Greater Manchester, Merseyside and south Lancashire and Area 13 covering north Lancashire and Cumbria. Each area team has a main, Managing Agent Contractor (MAC) which delivers routine maintenance, improvements and winter service arrangements such as gritting as well as providing Incident Support Units (ISUs) to help with traffic management and cleaning after incidents on motorways and Highways Agency A roads.
3. Maintenance and improvement projects: We plan maintenance and improvement projects carefully to allow road works to be completed safely, in a cost effective way while keeping disruption to road users to a minimum. We do as much work as possible overnight and when roads are less busy in order to keep more lanes open for road users at peak travel times. Drivers are advised to check their route for road works and allow extra time for their journeys where needed. We have a variety of journey planning tools that road users can use to check travel conditions on the roads we manage, and we will do all we can to keep road users informed.
4.Safety at roadworks: The Highways Agency is working with the industry and road users to reduce the risks of working on the roads. For the safety of road workers and all road users, when you are approaching roadworks:
- Keep within the speed limit – it is there for your safety.
- Get into the correct lane in good time – don’t keep switching.
- Concentrate on the road ahead, not the roadworks.
- Be alert for works’ traffic leaving or entering roadworks.
- Keep a safe distance – there could be queues in front.
- Observe all signs – they are there to help you.
5. Real-time traffic information for England’s motorways and other strategic roads is available:
