M6 Overnight Closures Start Tonight for Lowther Bridge Works

Drivers using the M6 south of Penrith face three weekends of overnight closures as major works continue on Lowther Bridge at Clifton.

The M6 will be completely closed Northbound between Junction 39 at Shap and Junction 40 at Penrith from 10pm until 6am tonight, Saturday 8 August, with further closures on:

  • Saturday 15 and Sunday 16 August
  • Saturday 22 and Sunday 23 August

The overnight closures are needed while National Highways installs new permanent expansion joints on the 50-year-old Lowther Bridge, which carries thousands of vehicles over the River Lowther every day.

The bridge is currently undergoing a £9 million refurbishment project, which includes replacing the expansion joints, waterproofing and resurfacing the bridge decks, improving drainage, repairing the concrete deck and supporting structures, and renewing the central reservation barrier.

National Highways expects the installation of the permanent expansion joints to be completed by the end of August.

During the overnight closures, signed diversion routes will be in place using the A6 and A66 between Junction 40 at Penrith and Junction 39 at Shap.

Drivers are being urged to plan ahead and allow extra time for their journeys.

The wider Lowther Bridge project began in March 2025 and is designed to extend the life of the structure for many years to come.
