Hobson Street, Macclesfield – sinkhole repair works
What we are doing
We are currently working alongside United Utilities and Cadent Gas to repair the carriageway collapse and damaged culvert on Hobson Street, Macclesfield.
We are installing a new manhole chamber on Ryle Street, opposite to where the initial carriageway collapse appeared. This will allow us to both divert/over-pump the culvert in Hobson Street and carry out further investigations into the cause of collapse on Ryle Street.
Works on Hobson Street as follows:
- the works are complex and will require us to fill in the existing excavation, in order to safely remove the ground supports that are currently in place
- following this, we will then put measures in place to protect the pressure gas main and re-excavate a larger hole in the road. This will allow us to install a temporary manhole on the damaged sewer
- pumping the sewerage can then start into the next available manhole which is at the junction with Ryle Street
- once this is in place, we will begin pumping the water that is running through the damaged culvert, over and into, the new manhole on Ryle Street
- at this point work can start to repair the damaged culvert
- work will then take place to reinstate the damaged carriageway
Once works have been completed on Hobson Street, works can then commence on Ryle Street to install a new manhole cover.
Throughout the duration of the works, there will be a representative from Cadent Gas on site, who will continue to monitor the condition of the equipment
When it is happening
Works commenced on the 15 April 2020 and a new inspection chamber has been installed on Hobson Street. This was an extremely complex piece of work which involved a great deal of coordination with National Grid Gas and United Utilities.
The next phase is to install a new inspection chamber on Ryle Street and we have worked closely with third parties to ensure we comply with current Health and Safety requirements. We are currently in the process of finalising a safe method of working which will enable works to commence on the installation of the new chamber opposite 18 Ryle Street.
Government guidelines regarding COVID-19
We will continue to comply with government guidance on social distancing however, as the teams will be working in pairs; we have supplied our staff with additional PPE. Due to the teams having to vacate the excavations to wash their hands regularly and adhere with guidance, the works may take longer than initially anticipated however the safety of our workforce remains our main priority. We therefore ask members of the public to be patient while these works take place and to not approach our staff on site or the work area.
We understand that there is no right time to undertake these works which have been carefully planned to try to minimise disruption to local residents, businesses and members of the travelling public. Delays are to be expected.
All roadworks, closures and diversions associated with the project are displayed online on the One Network map.
Information for road users
- The road and lane closures are necessary to protect the safety of both members of the public and our workforce whilst we complete the work.
- Where road closures are in place, diversion routes will be signed to assist in the movement of traffic while works progress.
- Delays are expected and motorists should plan essential journeys accordingly.
