When does the M6 closure end and what area is affected?

The M6 is closed between J39 and J40 over the weekend while engineers replace the Clifton Bridge. Works are concentrated into this window, with rail timetable changes expected until 15 January. Check live traffic and rail updates before travel, as reopening depends on safe completion and weather.

How will Avanti services change during the works?

Avanti West Coast is diverting via the Settle–Carlisle line on some services while engineering continues. Journeys may be longer and seat availability tighter. Timetables should normalise by 15 January. Always check the operator’s latest alerts on the morning of travel and allow extra time for connections.

What is the business impact of the M6 closure in Cumbria?

Expect higher delivery costs, rerouting, and staffing challenges across the weekend. Retail and hospitality may see softer footfall and late cancellations. Time-critical loads face the most risk. Many firms can offset disruption by rescheduling non-urgent trips, staging inventory, and prioritising high-margin shipments.

Are there long-term benefits from the £60m Clifton Bridge project?

Yes. The new bridge, plus 80 km of overhead line renewals and signalling upgrades, should improve reliability on the West Coast Main Line. Over time, fewer faults and more predictable timetables help passenger and freight operators, supporting steadier cash flow and better planning for regional businesses.
