Hollyhurst Road, Wrenbury drainage works

We will be carrying out drainage excavation work on Hollyhurst Road, Wrenbury, from 23 to 27 February. This is to help identify and fix the underlying cause of recent flooding in the area.
The works will take place between the junction of Hollyhurst Road and Wrenbury Road.

Why the work is needed

Flooding has been an ongoing issue at the junction of Hollyhurst Road and Wrenbury Road. Previous works in December 2024 cleared heavy silt and debris, improving the situation, but flooding returned in December 2025. Since then, we have:

• Cleared floodwater on several occasions
• Exposed a blocked manhole restricting jetting
• Carried out further jetting and CCTV inspections
• Addressed a contributing leak on Hollyhurst Road, repaired by a utility company
• Increased gully cleaning in the area

Investigations suggest a significant restriction in the drainage system, likely from root intrusion or structural damage. The drainage outfall also runs across private land, where ditch maintenance may be required to improve water flow.

When and what work is happening

Works to deliver this drainage investigation dig up works will take place from 23 to 27 February 2026 and the road will be closed between the hours of 9:30am to 3:30pm.

Further updates will be provided once the dig up investigation has been completed.

Road closure and diversions routes

Under current Health and Safety legislation and for the safety of our workforce and members of the public, it will be necessary for a road closure to be in place during these works.

Access for pedestrians and cyclists will be maintained at all times and cyclists will be asked to dismount.

Emergency services are aware of the planned closure and access will be facilitated if there is an emergency. They are also aware of the diversion arrangements in place for emergency vehicles to follow for the duration of the scheme.

Roadworks, closures and diversions are displayed online on our roadworks map.

Risk of flooding

The main type of flooding in this area is caused by rainwater that collects on the ground because it can’t drain away fast enough and is called pluvial flooding.

This occurs when intense rainfall overwhelms local drainage systems or exceeds the grounds’ ability to absorb water, which leads to pooling or overland flow. Flooding from surface water can happen anywhere, is hard to predict, and is often worsened in an area with a high concentration of impermeable surfaces. 

Further information on the risk of surface water flooding can be accessed on the Government webpage.

If you are concerned about flooding to your property, further information is provided by The Flood Hub.

You can also report instances of flooding on the highway or your property using our TraCE reporting system.
