National Highways and the LDNPA are seeking permission for a new traffic-free link connected to the Keswick to Threlkeld Railway Trail (K2T), intended to improve active travel connections.
Planning documents describe the scheme as a proposed 0.5-mile traffic-free, multi-user trail (MUT) linking Threlkeld Quarry to the existing route.
Its objectives include providing increased traffic-free travel opportunities between communities and creating a safer connection between National Cycle Network Routes 6 and 7 by avoiding the at-grade crossing of the A66 at Threlkeld.
The application has prompted a range of comments, including some concerns about parking, facilities, inclusivity and design, alongside support in principle for improving off-road links.
The LDNPA has emphasised the benefits of the proposal, saying it would improve safety and help ease pressure on village parking.
A spokesperson for the authority said: "As an accessible trail for all in the heart of the north Lakes, we're proud to be able to provide a smooth, safe Lake District route for more than 300,000 people every year, including many with mobility needs as part of our Miles without Stiles.
"The proposed extension of the Keswick to Threlkeld trail will create a safer crossing for the busy A66 road and reduce congestion pressure from visitor car parking in Threlkeld village.
"More than 75per cent of communities, businesses and visitors consulted were in support of the proposal to extend the trail when asked in 2024, with strong support for the proposed bridge across Station Road.
"Currently the planning application is still live, we continue to monitor all the representations with a view to making a decision next year."
The plans set out two sections. Section one would branch from the K2T near the 'Zig Zag', pass beneath the A66 and run through a field alongside the River Greta before climbing to Burns Road, proposed on a three-metre-wide tarmac surface with shallow gradients intended to be suitable 'for all'.
Section two would follow the former Cockermouth-Penrith railway, crossing the River Glenderamackin via the original bridge and continuing over Station Road on a new structure to reach the LDNPA's Threlkeld offices car park.
This section is proposed as a crushed stone surface, intended to be suitable 'for many' and to accommodate equestrians, alongside parapet upgrades on the existing bridge.
