Milton (Cambridge Tribune) July 27, 2026 – uk/local/milton/">Milton Road in Cambridge is set to reopen on Wednesday, 5 August 2026, following confirmation from Cambridgeshire County Council that repairs to a car-sized sinkhole are back on schedule after a temporary halt. The road had been expected to reopen sooner, but repair works were paused due to an issue identified by Anglian Water. That issue has since been resolved, allowing work to resume on Monday, 27 July.

When will Milton Road reopen after the car-sized sinkhole?

The planned opening date for a road where a sinkhole appeared has been confirmed. Repair works have been ongoing on Milton Road in Cambridge since a sinkhole appeared on 22 June. The road was expected to have been opened by now, however repair works had to stop due to an issue identified by Anglian Water. This issue has since been repaired, and work is set to continue today (Monday, 27 July). As long as works go to schedule, a Cambridgeshire County Council spokesperson has said the road will reopen on Wednesday, 5 August.

A council spokesperson added:

“The sinkhole will be filled with concrete. There may be times when no activity is visible on site, this is because the concrete needs time to set as it will be poured in phases. Surfacing and road marking works will then follow. Thank you again for your continued patience. We will keep you updated on further progress.”

What caused the delay in reopening Milton Road?

Earlier in July, Cambridgeshire County Council said work to fill the sinkhole would begin on 14 July, but it was unable to confirm when the road would reopen to traffic given the “unique nature of the works”. The council had previously stated its contractors planned to fill the hole with concrete to form a slab, which would then have to be left to dry for several days before excavation and backfilling could continue.

The delay arose after an issue was identified by Anglian Water during the repair process. Anglian Water had earlier confirmed it had “not identified any issues with our network at this location” and that its findings suggested recent works in the area were not connected to the incident. However, the presence of an issue requiring attention forced a pause in works until it could be resolved.

What is the scale of the sinkhole on Milton Road?

The sinkhole, estimated to be up to 3m (10ft) deep and the size of a family car, opened on Milton Road in Cambridge on 22 June. The road closure affected the section between Hurst Avenue and the Elizabeth Way roundabout, with the route remaining closed to motor vehicles though still accessible on foot or by bicycle.

Cambridgeshire County Council, which maintains the road, said the three-week delay between the hole opening and repairs starting was due to the need to “work sensitively around utilities within the sinkhole to avoid loss of services to local residents”. Investigations into the cause of the void were said to be continuing at the time repairs began.

How are repairs to the Milton Road sinkhole being carried out?

According to the council, the sinkhole will be filled with concrete in phases, with periods of inactivity on site reflecting the time required for the concrete to set. Once the concrete work is complete, surfacing and road marking works will follow before the road can be reopened.

A council spokeswoman told the BBC that digging out and filling the hole, which is the size of a family car, would take several more days to complete. The council had earlier stated that, given the unique nature of the works, it was unable to confirm when the road would reopen to traffic until more information was available.

What have Anglian Water and the council said about the incident?

Anglian Water confirmed awareness of the sinkhole and noted its presence at the site. In an earlier statement, the utility said:

“Preliminary CCTV examinations have not revealed any problems with our infrastructure at this site, and our current findings indicate that recent activities in the area are unrelated to this event.”

It added:

“We will continue to assist with the ongoing investigation alongside the highways authority, prioritising safety. Additionally, we are collaborating with partners on-site to reduce inconvenience for residents and local businesses.”

Cambridgeshire County Council has repeatedly thanked residents for their patience. A representative from the council stated:

“The road will be repaired as swiftly as possible and reopened as soon as it is deemed safe.”

The latest update confirms the target reopening date of 5 August, subject to works proceeding as planned.

Background: How the Milton Road sinkhole developed

The sinkhole opened on Milton Road, close to the Elizabeth Way roundabout, on Monday, 22 June 2026, prompting an immediate closure of the busy route in both directions. Cambridgeshire Police reported that officers responded to an incident on Milton Road at 10:39 on Monday, and the Cambridgeshire County Council confirmed the thoroughfare between Mitch Corner and Elizabeth Way roundabout was closed in both directions.

Teams from the highways department were deployed to investigate the underlying cause of the sinkhole, while Anglian Water carried out its own checks. The council said its contractors planned to fill the hole with concrete to form a slab, which would then have to be left to dry for several days before excavation and backfilling could continue. Work to repair the sinkhole was scheduled to start on Tuesday, 14 July, following further collaboration with Anglian Water.

However, repair works were subsequently halted due to an issue identified by Anglian Water. Once that issue was resolved, the council confirmed that work would resume on 27 July, with a target reopening date of 5 August if works remained on schedule.

Prediction: How the reopening could affect Cambridge residents and commuters

If Milton Road reopens on 5 August as planned, the development is likely to ease congestion for commuters relying on the route into Cambridge city centre, particularly those travelling from the north via the Elizabeth Way roundabout. The closure had forced drivers to use alternative routes, increasing journey times and putting additional pressure on surrounding roads.

Local businesses along Milton Road may also see a return to normal footfall and trade patterns once the road reopens, following a period of disruption. Residents who had been accessing the area on foot or by bicycle during the closure will regain full vehicular access, though the council’s warning about phased concrete pouring suggests there may still be short periods of reduced activity on site.

Should any further delays arise due to weather, concrete curing times, or unforeseen ground conditions the council’s commitment to providing updates will be critical in managing public expectations and minimising disruption.
