One of the Lake District’s best-known accessible walking and cycling routes will be interrupted for around eight weeks while a bridge is replaced.
The Keswick to Threlkeld Railway Trail will lose its through connection from Monday 7 September 2026. The Lake District National Park Authority says the affected section will be closed in both directions while essential bridge replacement work takes place.
The closure is on the traffic-free railway trail close to its Keswick end. It is not a closure of the A66 road bridge.
Keswick to Threlkeld closure at a glance
- Closure begins: Monday 7 September 2026
- Planned duration: Approximately eight weeks
- Through access: Not possible in either direction
- Closure limits: Grid references NY 27212 23760 to NY 27364 23741

No fixed reopening date has been announced. If the work lasts for the planned eight weeks, the route would be expected to reconnect around early November, but visitors should check the latest official update before travelling.
Where will the trail be closed?
The closed section lies close to the Keswick end of the route, between grid references NY 27212 23760 and NY 27364 23741.
The Lake District National Park Authority has also identified the two ends of the closure using What3Words as ///saving.thousands.weds and ///riddle.quilt.provide.
The barriers will prevent people passing through the works from either direction. Anyone setting out from the usual Keswick Leisure Centre and old railway station entrance should therefore not expect to complete the normal journey to Threlkeld.
The authority’s announcement does not provide a through diversion around the closed bridge. Trail users should plan a different route rather than attempting to bypass barriers or enter the construction area.
Can any of the Keswick to Threlkeld trail still be used?
Yes. The National Park Authority says approximately 4.5km of the route will remain available from the eastern side of the closed bridge through to the Threlkeld end.
Access to that open section will be available by a ramp from the footpath behind the filling station on Penrith Road. The approach uses the public footpath running between Latrigg Close and St Herbert’s Primary School on Trinity Way, off Windebrowe Road.
This access point is different from the trail’s usual level entrance beside Keswick Leisure Centre. People using wheelchairs, mobility scooters, adapted cycles or wide pushchairs should check the latest access information before setting out, as the alternative approach may not offer the same experience as the main entrance.
At the Threlkeld end, the trail meets the A66 before the route into the village. Visitors should remember that public parking in Threlkeld is limited and avoid parking on roads or verges where access could be obstructed.
What work is being carried out?
The project includes a replacement bridge deck made from recycled plastic and reinforced with steel, together with new guardrails and a new steel subframe.
The National Park Authority expects the renewed structure to have a working life of around 30 years. The design forms part of a wider programme to replace wooden bridge decks while respecting the appearance of the Victorian railway structures along the route.
The bridge stands within a sensitive Site of Special Scientific Interest. To reduce disturbance, steel components will be manufactured away from the site and the on-site assembly is planned using hand tools rather than heavy machinery wherever possible.
Visitors must follow all closure signs and stay outside fenced or signed work areas. Entering a construction site could endanger both trail users and the people carrying out the work.
Separate restrictions are already in place further east
The September closure is separate from bridge-deck work already under way nearer the Threlkeld end of the trail.
Earlier work covered two bridges at grid references NY 304245 and NY 306245, around 4km upstream from Keswick and approximately 1km from the Threlkeld end. One bridge has been completed, while work on the other is expected to finish at the beginning of September.
While that work continues, a temporary scaffolding footway allows most people to pass. However, its maximum width is only 75cm. The National Park Authority has warned that tricycles, wide pushchairs and some wider mobility scooters may not fit through.
This means some users could face restricted access before the full closure starts on 7 September. Anyone relying on a wider mobility aid or adapted cycle should check the current position directly with the authority before visiting.
Why the railway trail is so important
The Keswick to Threlkeld Railway Trail follows the former Cockermouth, Keswick and Penrith railway through the wooded River Greta gorge.
The route is approximately 5km each way and is commonly promoted as a 10km return trip. Its gentle gradients, surfaced path, regular seating and traffic-free setting make it popular with walkers, runners, families, cyclists and people using mobility aids.
It is one of the Lake District National Park’s Miles Without Stiles routes and also forms part of National Cycle Network Route 71 and the wider Coast to Coast cycling route.
The trail was severely damaged by Storm Desmond in December 2015, when bridges and sections of path were washed away. It reopened in December 2020 following a £7.9 million reconstruction project that added new bridges, repaired existing structures, restored the Bobbin Mill tunnel and improved resilience to future flooding.
That history helps explain why planned maintenance matters. The route is more than a leisure path: it provides an important traffic-free connection between Keswick and Threlkeld and gives many people access to the landscape who may find rougher paths unsuitable.
Planning a visit during the closure
People visiting between 7 September and the eventual reopening should plan on the basis that the full Keswick to Threlkeld journey is unavailable.
- Do not start from Keswick Leisure Centre expecting to reach Threlkeld on the railway trail.
- Use the alternative Penrith Road access only for the open eastern section identified by the National Park Authority.
- Do not attempt to cross barriers or improvise a route through the bridge works.
- Check whether any mobility aid, adapted cycle or pushchair is suitable for the available access.
- Check current bus times if planning a linear outing between Keswick and Threlkeld.
- Allow for changing autumn weather and reduced daylight later in the closure period.
Stagecoach’s X4 and X5 services connect the Penrith, Threlkeld, Keswick, Cockermouth and Workington corridor. Timetables can change, so passengers should confirm their journey on the day rather than relying on an older printed schedule.
There are no public toilets along the railway trail itself. The National Park route information identifies facilities near Bell Close car park in Keswick and at Threlkeld Village Hall and Coffee Shop, subject to their opening arrangements.
When will the full trail reopen?
The authority has described the closure as lasting eight weeks from 7 September 2026 but has not published a guaranteed reopening date.
Construction schedules can be affected by site conditions, weather and the requirements of working in a protected habitat. Cumbria Guru will update this article when a confirmed reopening date or a change to the access arrangements is announced.
