Cornton Road Stirling Sewer Repair
Full Closure
Cornton Road is a key route through Stirling along the east bank of the River Forth. A full closure is in place to allow repair work to be carried out safely.
We are carrying out urgent an sewer repair on Cornton Road in Stirling after a sinkhole appeared close to the junction with Bridgehaugh Road.
Our teams have made the site safe and repaired a burst water main, which was found to have contributed to the appearance of the sinkhole in the road and to have caused damage to a manhole.
Work is now underway on the next phase of repairs which is both challenging and technical involving a deep excavation of more than five metres.
Once the sewer has been repaired, the process of filling in the sinkhole and reinstating the carriageway can begin.
No Way Through
Diversions are in operation
A full road closure is required on Cornton Road to ensure the safety of the public and our operatives. Diversions are in place including an alternative route for high sided HGVs to avoid a low rail bridge.
We estimate the repairs will take approximately eight weeks to complete.
We appreciate that the road closure will cause some disruption for residents and road users and thank them for their patience and understanding while we carry out this essential work safely.
The work is being carried out by Clancy who will work with residents to minimise disruption.
The damaged sewer is more than five metres underground
Road users are being advised to plan ahead
Update 21 April 2026
The first phase of work connecting a property to the network has been completed and the deep excavation backfilled to allow us to reinstate the road surface.
The next stage requires a large 30 tonne excavator to dig down over five metres to allow us to repair a defective manhole.
The situation has been complicated by the presence of a fire hydrant and six-inch water main encased in concrete within the area we need to excavate which must be moved to allow work to progress safely.
Ordinarily this would involve a planned loss of supply for approximately 1000 customers as well as Cornton Vale prison. However, our team have developed a plan to use a fleet of tankers to ensure the water supply is maintained while the work is carried out safely.
This will take place on Wednesday 22 April 2026.
The tankers will back feed the clean water supply, allowing the redundant six-inch pipe to be removed and a new pipe installed. Vehicles may need to block some driveways and residents requiring access should speak to our team on site to arrange. Everything will be done to accommodate them.
We expect the water main work to be completed on the same day allowing us to resume excavations and repairs on the damaged sewer manhole.
Once the manhole has been rebuilt, we can then begin the final phase of the work, to dig out the full extent of the sinkhole before reinstating it.
This will be the most complex and challenging part of the repair given the lack of structural integrity of the road surrounding it. Safety must come first therefore every care will be taken to keep our operatives and also other critical infrastructure and utilities in the sinkhole safe.
Everything is being done to mitigate disruption, and we remain extremely grateful for the patience, understanding and cooperation of the community and all those affected.
Repairs are expected to be completed and the road reopened by the end of May.
Emergency services were made aware of the full closure at the time and have planned accordingly.
First Phase Finished
The first phase of the work to connect a property to the sewer network has been completed after excavating down more than five metres.
