The M6 is one of the busiest motorways in the West Midlands, carrying thousands of drivers between Walsall, Birmingham, Coventry and the national road network each day. Major resurfacing, maintenance and HS2 construction work has created a series of planned restrictions during 2026. These works include full overnight closures, lane reductions and short-term traffic management near key junctions.
The important current scheme affects the southbound carriageway between Junction 6 at Spaghetti Junction and Junction 4 near Coleshill. Other work has taken place near Junctions 4 and 4A, while Walsall drivers continue to face heavy traffic near Junction 10 during peak periods.
This guide explains the M6 Walsall Birmingham Lanes Closure programme, the dates drivers need to know, the roads affected and how to prepare for delays.
M6 Walsall Birmingham Lanes Closure: What Is Happening?
The main 2026 programme involves resurfacing the M6 southbound between Junctions 6 and 4. The work began in March and is due to continue until October 2026. National Highways has divided the scheme into several phases so that crews can renew the road surface while keeping part of the motorway open whenever possible.
Many restrictions take place overnight, usually from 9pm until 6am. Full closures are required during the most demanding stages because workers, vehicles and heavy machinery need safe access to the carriageway.
M6 Southbound Closure Between Junctions 6 and 5
The section between Junction 6 and Junction 5 is an important part of the scheme. Junction 6 connects the M6 with the A38(M), Birmingham city centre and Spaghetti Junction. Junction 5 serves Castle Bromwich and nearby communities.
Full overnight closures are planned on weeknights from 22 June to 17 July 2026. During these closures, southbound traffic cannot travel directly between Junctions 6 and 5. Drivers must leave the motorway and follow the signed diversion.
These restrictions can create serious long queues before the closure starts, especially during the evening rush hour. Traffic may also build on local roads as vehicles move through Birmingham and Castle Bromwich.
July Lane Restrictions
From 20 July to 31 July 2026, the motorway will move into a different phase. Three southbound lanes are due to close overnight, while the hard shoulder will open as a running lane.
This arrangement will keep traffic moving, but capacity will be reduced. Drivers should expect slower journeys, lower speed limits and narrow traffic lanes through the work zone.
Full Overnight Closures Planned for August and Autumn
The M6 Walsall Birmingham Lanes Closure programme does not end in July. Further full overnight restrictions are planned during August, September and October.
August 2026 Closures
Full overnight closures between Junctions 6 and 5 are due to return from 3 August to 14 August. These works will continue on weeknights, with the motorway normally reopening by 6am.
Later phases may include lane closures rather than complete carriageway shutdowns. The arrangement can change because of weather, safety concerns or progress on earlier sections.
September and October 2026 Closures
Another full closure phase is scheduled from 1 September to 8 September. Further overnight closures are planned from 28 September until 16 October.
The October date marks the expected end of the main resurfacing programme. Drivers should still check traffic conditions before setting off, as repair work can be delayed or moved.
M6 Junctions 4 to 4A HS2 Works
HS2 construction has also affected the M6 near Birmingham. Junction 4 connects with the M42 and routes towards Birmingham Airport, while Junction 4A is part of the complex motorway interchange east of the city.
Temporary overnight lane closures took place in both directions between Junctions 4 and 4A from 29 June until the morning of 4 July 2026. Lanes two and three were closed so teams could carry out lighting surveys in the central reservation.
Those particular restrictions had finished by 9 July 2026. However, HS2 work remains active across the wider motorway network, and new closures may be introduced as bridge and engineering operations continue.
Why HS2 Work Affects the M6
HS2 construction requires large structures, utility changes, lighting work and motorway protection measures. Some tasks can only be completed when traffic is reduced or removed from part of the road.
The M6 and M42 interchange is sensitive because it carries traffic towards Birmingham, Coventry, Solihull, the NEC and Birmingham Airport. Even a short overnight closure can cause delays on nearby roads.
M6 and M42 Link Restrictions
A closure of the M6 to M42 eastbound link road was expected from 13 July to 15 July 2026 during overnight hours. Larger weekend engineering work was also planned for later parts of July, August and September.
Drivers heading towards the airport or the M42 should pay close attention to temporary signs and diversion boards.
M6 Junction 10 Walsall Traffic Conditions
Junction 10 is the main M6 connection for Walsall and Wolverhampton. It links the motorway with the A454 and carries heavy traffic during the morning and evening peaks.
The Junction 10 improvement project has been completed. The final major stage opened in March 2024, and traffic controls linked to the scheme were removed.
It is therefore wrong to describe the main Junction 10 upgrade as an active construction project in 2026. However, congestion remains possible because the junction serves a busy urban area and can be affected by accidents, maintenance and local roadworks.
Why Delays Still Happen Near Junction 10
Even after the upgrade, traffic can slow because of high demand. Vehicles entering and leaving the motorway create pressure on the slip roads, while incidents elsewhere on the M6 can quickly cause queues to spread towards Walsall.
Drivers travelling from Junction 10 towards Birmingham should also remember that restrictions farther south may affect their journey. A closure near Junction 6 can produce delays miles before the actual work zone.
A4540 Lawley Middleway Crash Was Not an M6 Closure
A separate crash caused disruption on Birmingham’s inner ring road on Wednesday, 8 July 2026. The collision happened shortly before 11am on the northbound A4540 Lawley Middleway near Garrison Circus.
The road was blocked between Great Barr Street and the B4132 Vauxhall Road near Curzon Circus. Traffic was diverted, and heavy queues developed east of Birmingham city centre.
The incident had cleared by 12.56pm, and traffic returned to normal. It was not part of the M6 Walsall Birmingham Lanes Closure programme and did not involve a motorway carriageway closure.
Possible Knock-On Effects
Although the crash was not on the M6, it may have affected vehicles heading towards the A38(M) and Junction 6. Local traffic moved onto alternative roads, creating extra pressure near Garrison Circus, Vauxhall Road, Curzon Street and other eastern city routes.
This distinction matters because planned motorway works and sudden road collisions require different travel plans. Overnight works can be prepared for in advance, while collisions may cause immediate changes without warning.
M6 Northbound Closures Near Birmingham
The main resurfacing programme between Junctions 6 and 4 is focused on the southbound carriageway. There was no matching full northbound closure between Walsall and Birmingham under this phase on 9 July 2026.
Northbound lane restrictions may still be introduced for maintenance, inspections or HS2 work. Drivers should not assume the route will always be fully open simply because the major scheme is southbound.
M6 Junction 36 Is Not Near Birmingham
Junction 36 is near Kendal in Cumbria, far from Walsall and Birmingham. Closure notices for Junction 36 relate to the northern M6 and should not be confused with West Midlands restrictions.
A drainage scheme near Junction 36 had included a long-term lane closure, but that phase was due to finish on 19 June 2026. Anyone planning a long journey should check each motorway section separately.
How to Plan for the M6 Walsall Birmingham Lanes Closure
Planning can prevent a journey from becoming a long and stressful delay.
Check the Date and Direction
Drivers should confirm whether they are travelling northbound or southbound. Most of the major 2026 resurfacing closures affect southbound traffic between Junctions 6 and 5.
They should also check whether the trip falls during a full closure phase or a lane-restriction phase. A full closure requires a diversion, while a lane closure may only add extra time.
Travel Before the Closure Starts
Where possible, motorists should pass through the affected area before 9pm. Leaving only a few minutes before the scheduled closure can still lead to delays because traffic often slows as cones and signs are placed.
Allow Time for Diversions
Signed diversions may use busy urban roads. Heavy goods vehicles, coaches and long-distance traffic can make these routes slower than normal.
Keep Fuel and Battery Levels Safe
Drivers should begin the journey with enough fuel or electric charge to cover delays. Queues, stop-start traffic and diversion routes can increase energy use.
Final Travel Advice
The M6 Walsall Birmingham Lanes Closure programme is a major 2026 road project that will affect southbound travel at several points between July and October. The most serious disruption centres on Junctions 6 and 5, where full overnight closures and three-lane restrictions are planned.
HS2 work near Junctions 4 and 4A adds another layer of disruption, although some early July restrictions have already finished. Junction 10 in Walsall remains busy, but its main improvement scheme is complete.
Drivers should separate planned M6 works from unrelated incidents such as the A4540 Lawley Middleway crash. They should also avoid confusing Birmingham closures with Junction 36 in Cumbria.
By checking the direction, date, junction and expected closure time before travelling, motorists can choose better routes, avoid the busiest periods and reduce the risk of lengthy delays.
FAQs
1. When will the M6 Walsall Birmingham lanes closure take place?
Most planned closures take place overnight, usually between 9pm and 6am. Restrictions may include full carriageway closures, reduced lanes or use of the hard shoulder as a temporary running lane. Dates can change because of weather or delays to the work.
2. Which M6 junctions are most affected?
The main resurfacing work affects the M6 southbound between Junction 6 and Junction 5. Further work has also taken place between Junctions 4 and 4A because of HS2 construction. Junction 10 in Walsall may face congestion, but its main improvement scheme is complete.
3. Are there any northbound M6 closures near Birmingham?
The largest 2026 resurfacing project mainly affects the southbound carriageway. However, temporary northbound lane closures may still be introduced for inspections, maintenance or HS2 work. Drivers should check traffic updates before travelling.
4. What should drivers do during a full M6 closure?
Drivers should follow the official yellow diversion signs and allow extra time for their journey. Local roads may become busy because motorway traffic is redirected through Birmingham, Castle Bromwich and nearby areas.
5. Is the A4540 Lawley Middleway crash connected to the M6 works?
No. The crash on Lawley Middleway on 8 July 2026 was a separate road incident on Birmingham’s inner ring road. It was not caused by the M6 resurfacing scheme, although diverted traffic may have increased congestion on routes leading towards M6 Junction 6.
