Motorists in the West Midlands are being warned of significant disruption as the M42 is set to close in both directions between junctions 5 and 6 for five weeks, starting at 8pm on Friday, to allow for HS2 construction works.
The closure, which will see the motorway shut between Solihull and Birmingham Airport, is part of the high-speed rail project's ongoing development in the region. National Highways has confirmed that the stretch of motorway will remain closed until further notice, with a clearly signed diversion route in place for drivers.
Diversion route and expected impact
During the closure, traffic will be diverted via the A45 Coventry Road and the A452, with additional signage directing motorists through the local road network. The diversion is expected to add considerable time to journeys, particularly during peak hours, and drivers are being urged to allow extra travel time or consider alternative modes of transport.
The five-week timeframe is necessary to complete essential bridge works and other infrastructure improvements linked to the HS2 project. According to National Highways, the work is part of the preparation for the new high-speed rail line, which will run parallel to the M42 in this area.
HS2 progress and regional connectivity
HS2 is the UK's flagship rail infrastructure project, designed to improve connectivity between London, Birmingham, and the North of England. The section of the M42 affected by this closure is a key corridor for both local commuters and long-distance traffic, making the disruption particularly impactful for businesses and residents in Solihull and the wider West Midlands.
Once completed, HS2 is expected to significantly reduce journey times between major cities, with trains running at speeds of up to 225mph. The project has faced repeated delays and cost increases, but recent updates from HS2 Ltd indicate that the Birmingham to Crewe section remains on track for completion in the early 2030s.
Local authorities and transport officials have been working to minimise the impact of the closure, with advanced warning signs placed on approach roads and real-time traffic updates available through National Highways' digital channels. Drivers are being encouraged to check traffic conditions before setting off and to follow the diversion signs carefully to avoid congestion in residential areas.
The M42 closure is one of the most significant road disruptions in the West Midlands this year, and its effects are expected to be felt across the region. With the school summer holidays beginning, the timing may also affect holiday traffic heading to Birmingham Airport, which is located near junction 6.
National Highways has stated that the motorway will reopen as soon as the works are completed, with the aim of minimising the duration of the closure. However, the exact reopening date will depend on weather conditions and the progress of the construction work.
For the latest updates on the M42 closure and diversion information, motorists are advised to visit the National Highways website or follow their social media channels. The organisation has also set up a dedicated phone line for travel enquiries during the closure period.
The impact of this closure will be closely monitored, and further announcements will be made if the schedule changes. In the meantime, drivers are urged to plan their journeys carefully and to consider using public transport where possible to reduce pressure on the diversion routes.
