A housing developer has issued an update about a sinkhole that opened on a Darwen new-build estate last September just yards outside a home's front door.
Tilia Homes said work to repair the sinkhole, which was around 104 feet deep, is ongoing and that the main access road in the estate is set to remain closed until October.
The sinkhole appeared on a new-build estate in Darwen on September 21, 2025, in the driveway of 6 Greenfield on the Tilia Homes development off Pole Lane.
The incident led to the evacuation of several residents, who were relocated to alternative accommodation.
A car on the drive was left overhanging the abyss, and the incident raised concerns about building works in areas with a legacy of mining.
In an update issued on August 26, Tilia Homes said: "The utility infrastructure works are now complete, with essential services reconnected to the affected homes.
"Work is continuing on the external works, including the topping of driveways.
"These works are scheduled for completion by the end of September.
"The main road is expected to reopen by mid-October."
The Mining Remediation Authority (MRA), a government organisation responsible for managing the legacy of coal mining across Great Britain, investigated the incident.
Last year, it confirmed the sinkhole is approximately 32 metres deep and suggested the collapse may be linked to "former sandstone workings" beneath the site.
In earlier updates, Tilia Homes explained the remediation process.
On August 3, the developer said: "The shaft has been successfully capped and backfilled.
"Work is now progressing on the utility infrastructure, with teams completing the remaining below-ground works and reconnecting essential services to the affected homes.
"These activities will continue over the coming weeks as work moves towards reopening the original access road."
A July 27 update detailed progress on stabilising the affected area.
Tilia Homes said: "The concrete cap at the top of the shaft has now been poured and is approaching the end of its required seven-day curing period.
"This allows the concrete to achieve the strength needed before work can safely continue.

"Once the engineers have confirmed the concrete has reached the required strength, the next phase of the project will begin.
"This will involve backfilling the excavation, preparing the surrounding area, completing the remaining groundworks and below-ground infrastructure, reconnecting the necessary utility services to the affected homes and opening the original access road."
The Mining Remediation Authority and Tilia Homes have been approached for comment.
