Derby Bridge Security Deployed as Collapse Risk Rises: key details

Derby City Council has deployed 24-hour security at Darley Abbey Mills Bridge after warning that the closed structure has deteriorated significantly and now poses a serious risk of collapse.

The council said members of the public must stay away from the fenced-off site, including the bridge, the water nearby and the area around the weir. Security staff will be stationed on the village, or west, side of the bridge to deter trespass and protect public safety.

Temporary lighting has also been installed so security teams can monitor the area more clearly.

Public told to stay away from the bridge and water

The council said the condition of Darley Abbey Mills Bridge has worsened over recent weeks. Despite the existing closure and fencing, more people have been forcing access to the restricted site.

Officials warned that the risk of collapse has now “significantly increased”. If the structure were to fail, the council said it could create a severe risk to life for anyone on the bridge or in the water around it.

The warning also covers the area close to the weir. Residents and visitors are being told not to enter the water near the bridge or the weir under any circumstances.

The safety concern is not limited to the bridge itself. Derby City Council said a collapse could also threaten local infrastructure, including Walters Walkway, the weir and utilities in the area.

Emergency powers to dismantle the structure

Derby City Council said it will use emergency powers under the Building Act 1984 to take direct action to dismantle the bridge and remove the immediate danger.

The decision means the authority is preparing to move faster than a standard repair or removal programme would usually allow. The council said the aim is to reduce the risk to the public and protect nearby infrastructure.

Removing Walters Walkway and dismantling Mills Bridge is expected to be a complex operation. The council said it is working with partners to speed up the project where possible, but several practical obstacles remain.

One of the main issues is finding enough space and a sufficiently hard foundation to position a crane for the work. That kind of logistical constraint can affect how quickly the dismantling operation can begin and how it is carried out.

Security stationed on the village side

The round-the-clock security presence will be based on the village side of Darley Abbey Mills Bridge. The council said the measure is intended to stop trespassers entering the fenced-off site and to reduce the chance of anyone being harmed.

The temporary lighting is part of the same safety response, giving security teams a clearer view of the restricted area during darker hours.

The council’s message to the public is direct: do not force access, do not go onto the bridge, and do not enter the water nearby.

Local routes and infrastructure remain affected

The closure continues to affect people who use the Darley Abbey area, including those who would normally rely on local walking routes around the bridge and Walters Walkway.

The council acknowledged that the closure is frustrating, but said the current condition of the structure leaves no room for public access. The site remains closed while emergency action is prepared.

Councillor Carmel Swan, Cabinet Member for Climate Change, Transport and Sustainability, said the bridge is in a “critical and dangerous state” and urged residents to support the safety measures.

“We cannot stress enough how important it is that people stay away,” she said. “It is deeply concerning that some are still forcing access to the site.”

Council focus shifts to removing the danger

The immediate next stage is for Derby City Council and its partners to progress the dismantling plan while managing the practical challenges around site access, crane positioning and infrastructure protection.

Cllr Swan said the council is using emergency powers and 24/7 security “for one reason: to keep people safe”.

“Please, do not take unnecessary risks, stay clear of the site, don’t force access to the bridge under any circumstances and do not go in the water in the vicinity of the bridge or the weir,” she said.
