Major delays on M6 and M42 as highways warning issued

Drivers heading through Coventry and Warwickshire today are facing major delays on the M6, M42, A42 and key stretches of the M1, as a combination of planned closures, HS2 construction work and congestion triggers a highways warning for some of England’s busiest interchanges.

Heavy congestion around Coventry and Rugby on the M6

Live traffic information for Saturday 7 November 2026 shows sustained congestion on the M6 northbound between junction 1 for Rugby and junction 2 for Coventry, with delays reported through late morning as traffic volumes increase at the start of the weekend getaway. Publicly available incident feeds indicate queues and reduced speeds in both directions at various points between Rugby, Coventry and the link towards the M69.

These delays come on top of a dense programme of overnight and multi-day works along the M6 corridor. Data compiled from National Highways schedules and third-party traffic trackers highlights more than 180 planned closures on the motorway between 6 and 20 November 2026, including carriageway, lane and slip-road shutdowns that can leave residual congestion after they reopen. Several of these closures are clustered around key interchanges serving Coventry and Warwickshire.

Among the most significant restrictions is the M6 southbound closure between junction 6 and junction 5 overnight from 21:00 on 6 November to 06:00 on 7 November for maintenance, with additional works affecting links to the M42. While these works are scheduled outside peak daytime hours, reports indicate that any overrun or early-morning queues can spill into daytime travel, particularly on Saturdays when traffic for shopping, events and airport journeys is heavier.

The concentration of schemes along this stretch means drivers encountering only minor incidents may still experience notable delays. Reduced speed limits, narrowed lanes and intermittent lane closures combine to limit the capacity of the motorway, especially where it passes close to Coventry and key junctions for the A46 and M69.

M42 and HS2 works tighten a key Warwickshire corridor

Conditions on the M42 are being shaped by a mix of HS2 construction activity and a long-running upgrade programme at junction 6 near Birmingham Airport and the National Exhibition Centre. National Highways and HS2 project documents outline southbound and northbound restrictions between junctions 6 and 9 during autumn 2026, including weekend and overnight closures as bridge structures and viaduct sections are installed.

In parallel, live closure data suggests around 50 planned closures on the M42 between 6 and 20 November 2026, with the majority scheduled between 19:00 and 06:00. Around half of these involve full carriageway shutdowns rather than just lane or slip-road restrictions, creating a significant risk of diversion traffic overspilling into A-roads across North Warwickshire and the outskirts of Coventry.

HS2-related notices point to temporary full weekend and overnight closures between junctions 5a and 9, and around links with the M6 at junction 4 and 4A, during the late summer and autumn period. While many of the heaviest closures fell in late October and early November, the network continues to operate with altered layouts, reduced speed limits and localised lane closures, which contribute to slower journeys even when the motorway is technically open.

For drivers, the result today is a tightly constrained corridor where any incident or minor collision can rapidly generate long tailbacks. With the M42 acting as a feeder to the M6, M40, A42 and routes towards Birmingham and the East Midlands, disruption in one location is quickly felt across a wide area of the West Midlands and Warwickshire.

A42 and M1 delays ripple across the wider network

Further north and east, the A42 and connected sections of the M1 are also experiencing pressure. HS2 route maps and regional planning documents highlight how diversion strategies during closures on the M42 and M6 can shift traffic towards the A42 corridor linking the East Midlands with the West Midlands, particularly for drivers heading between Birmingham, East Midlands Airport and the Nottingham and Derby areas.

Travel information services note that when weekend or overnight closures affect the M42, some long-distance traffic diverts via the A5 and A42 to reach the M1, adding extra volume to roads that already handle a significant mix of freight and regional commuter traffic. Recent community reports from professional drivers in the region have also described increased use of these corridors whenever HS2 or maintenance closures take place on the main motorways.

On the M1 itself, digital mapping and traffic tools in recent months have highlighted intermittent closure alerts along the central section, from around the M45 and M6 connections north towards the East Midlands. On days when planned works coincide with higher weekend demand, this can lead to slower journeys for travellers connecting from Coventry and Warwickshire via the A45, A46 or M45 towards the M1.

The combination of works, diversions and high traffic volumes means that those relying on the A42 and M1 as alternatives to the M6 and M42 today may still experience delays rather than clear runs. Journeys that involve multiple motorway changes, particularly near major junctions and service areas, are especially vulnerable to disruption.

What today’s warning means for drivers in Coventry and Warwickshire

The highways warning in place today effectively reflects a convergence of factors across the regional network, instead of a single isolated incident. Maintenance schemes on the M6 around Birmingham and Coventry, HS2 construction works straddling the M6 and M42, and a dense calendar of planned closures from early to mid-November have left limited spare capacity across motorways that serve Coventry, Rugby, Nuneaton and Warwickshire’s northern towns.

For those starting their journeys in Coventry and Warwickshire, the pinch points are likely to be the M6 between junctions 1 and 4A, the M42 around junctions 6 to 9, and the feeder routes that connect to the A42 and M1. Publicly available live-traffic dashboards show how queues can quickly build upstream of these locations, including on the approaches from the A46 Coventry Eastern Bypass and the A45 towards Birmingham Airport.

Travel planners consistently recommend that drivers check live traffic maps and motorway incident feeds shortly before departure, paying particular attention to the expected end times of any lane or carriageway closures. With many of the November works programmed during evening and overnight periods, normal conditions might not fully return by the early morning, especially after complex engineering operations or adverse weather.

Motorists heading to airports, major events or time-critical connections are advised by travel services to allow extra time and to consider whether alternative routes using A-roads might provide more predictable, if slower, progress. However, with the A5, A45 and A46 also acting as diversion corridors, any route choice today in and around Coventry and Warwickshire is likely to require patience and careful planning.

Tips for planning journeys through the affected corridors

Across central England, journey-planning tools now aggregate data from National Highways, local authorities and live sensor networks, providing real-time incident updates for routes including the M6, M42, A42 and M1. These platforms typically display the expected time for normal traffic conditions to resume and highlight whether delays are due to a collision, a broken-down vehicle, severe weather or planned maintenance.

For drivers travelling through Coventry and Warwickshire today, practical steps include checking motorway alerts just before departure, setting navigation apps to avoid motorways if severe incidents are reported, and monitoring matrix signs for warnings of closures or queuing traffic ahead. Publicly available guidance also suggests that where long stretches of variable speed limits or contraflow systems are in place, maintaining steady speeds within the signed limits can help reduce the stop-start waves that worsen congestion.

Coach operators, airport transfer services and freight companies moving through junctions such as M6 junction 2 for Coventry and junction 3A for the M42 and M6 Toll have been adapting schedules around the November works programme. While not all disruption can be avoided, there is scope for individual travellers to do the same by shifting departure times away from the busiest mid-morning and late-afternoon periods on Saturdays.

With intensive works on both the strategic motorway network and the HS2 construction corridor set to continue through November 2026, today’s pattern of disruption illustrates how tightly interlinked the M6, M42, A42 and M1 now are for journeys in and out of Coventry and Warwickshire. Travellers can expect conditions to remain changeable and should continue to rely on up-to-date traffic information when planning routes across the region.
