IN Brief:
- Walter's Walkway is scheduled to be lifted back into position at Darley Abbey on Thursday 22 October.
- Road closures and parking restrictions will apply around Darley Street and Old Lane from 19 to 23 October.
- New access ramps and further safety checks are required before reopening, and the council has not confirmed an opening date.
Derby City Council has scheduled the reinstatement of Walter’s Walkway at Darley Abbey for Thursday 22 October, following demolition of the structurally unsafe original Mills Bridge over the River Derwent. The temporary pedestrian crossing was removed in July to allow the old structure to be demolished and is now due to be lifted back into position. Further engineering checks and installation of new access ramps will be required before the walkway can reopen to the public.
The lifting operation will require road closures and parking restrictions around Darley Street and Old Lane from Monday 19 October until Friday 23 October. An exclusion zone will be established around the site to prevent public access during the work. The council has warned that the timetable remains subject to change and has not confirmed a date for pedestrians to begin using the reinstated crossing.
Walter’s Walkway was installed in 2022 after the original Darley Abbey Mills Bridge became unsafe. The older structure had provided access between Darley Abbey village and the historic mills complex, but deterioration led to its closure. The council provided the temporary walkway as an interim connection while proposals for a permanent replacement crossing were developed.
The temporary bridge remained in use until December 2025, when erosion and damage affecting the riverbank led to its closure. Subsequent engineering investigations identified serious concerns about the condition of the surrounding ground and the original bridge. The council concluded that the existing structure presented an unacceptable safety risk and that its removal was necessary before the temporary walkway could be returned to public use.
The investigation found that deterioration around the riverbank had affected the stability of the crossing. Supporting ground conditions are critical to bridge foundations because they must carry structural loads without unacceptable settlement or movement. Erosion can remove material that contributes to that support, requiring the affected area to be investigated and stabilised before the crossing can safely operate.
Derby City Council subsequently progressed the demolition of the original bridge, which had been constructed during the 1930s. Its structural condition had continued to deteriorate after closure, with engineers identifying a significant risk of collapse. The authority used emergency powers under the Building Act 1984 to address the immediate danger, while coordinating the work with specialists and the organisations responsible for nearby infrastructure.
The location presented substantial construction constraints. Walter’s Walkway occupied a position above the old bridge, preventing the demolition team from obtaining the access needed to remove the original structure. The temporary walkway therefore had to be lifted away before demolition could proceed, requiring ground stabilisation and a suitable working platform for heavy lifting equipment.
Contractor Cawarden undertook preparatory works for the July removal operation. The programme included installation of 28 sheet piles measuring six metres long and the placement of approximately 250 tonnes of material to form a crane platform. These temporary works provided the necessary conditions for a crane rated in the 470-tonne capacity class to lift the walkway clear of the river.
The walkway was lifted out in July and placed on Old Lane, exposing the original Mills Bridge for demolition. The 470-tonne figure relates to the crane used during that completed removal operation, not the weight of Walter’s Walkway. The council has not published the crane specification for the forthcoming October reinstatement, so the earlier lifting arrangement should not be treated as confirmation that identical equipment will be used.
With Walter’s Walkway removed, the demolition team was able to progress work on the old bridge. Derby City Council confirmed on 25 August that demolition had been completed, removing the deteriorated structure that had prevented the temporary crossing from reopening. Work nevertheless continued at the site because removing the immediate structural hazard did not establish that the walkway could be returned to public service without further checks.
The reinstatement now scheduled for 22 October will return the temporary structure to its position over the River Derwent. The council has not disclosed the detailed lifting plan, the temporary support arrangements or the condition of the equipment after storage on Old Lane. These matters will be addressed through the construction and safety arrangements for the operation, but no particular method can be attributed to the contractor without further information.
Once the walkway is back in place, engineers will undertake additional checks and install new access ramps. The ramps will provide the connection between the bridge and its approaches, allowing pedestrians to use the structure when the necessary safety conditions have been met. The council has not specified the ramp construction, final levels or inspection programme, and the lifting operation alone must not be described as completion of the crossing.
The road restrictions from 19 to 23 October will support access to the working area and protect the public during the planned operation. The exclusion zone will also cover the immediate site around the river crossing. Derby City Council continues to advise people to remain outside the fenced area and avoid entering the water near the former bridge and weir while construction activities remain underway.
Working beside the River Derwent introduces constraints associated with ground conditions, temporary works and the positioning of lifting equipment. The completed July operation demonstrated the need to prepare the working area before moving the structure. The forthcoming reinstatement must similarly account for access and stability, although its precise engineering arrangements have not been published.
The crossing is located within the Derwent Valley Mills World Heritage Site, where construction and demolition must also take account of historic infrastructure and its setting. The council has involved conservation and archaeological specialists in the wider bridge programme, including the demolition of the original structure. Those requirements form part of managing work around a historically significant site, without changing the temporary nature of Walter’s Walkway.
The longer-term replacement project is being developed separately. Derby City Council has published a Strategic Outline Business Case for a permanent bridge capable of providing access for pedestrians, cyclists and emergency vehicles. Further design work, funding decisions and approvals will be required before a permanent crossing can proceed to construction. Reinstatement of Walter’s Walkway is intended to restore interim pedestrian access rather than complete that larger project.
Funding from the East Midlands Combined County Authority has supported the urgent response to the unsafe original bridge and the development of a permanent replacement. The council has previously outlined separate funding requirements for demolition and longer-term access. The October update does not disclose a new contract value specifically for reinstating Walter’s Walkway, and the broader programme’s funding should not be presented as the cost of the scheduled lift.
The loss of the crossing has affected access between Darley Abbey village and the mills complex, prompting the council to prioritise the safe restoration of a pedestrian route. Reinstating the walkway should provide an interim connection once the remaining construction and inspection requirements have been met. The council has not claimed that the new access arrangements will match the capability of the permanent bridge being considered for the site.
The next construction milestone is the planned lift on 22 October, with road restrictions scheduled through 23 October. Further checks and ramp installation will follow before the council can announce a reopening date. The original Mills Bridge has already been demolished, but Walter’s Walkway remains closed until the outstanding works are completed and the crossing is confirmed safe for public use.
