A section of the road in Aylesbury has been closed around the clock after a sinkhole appeared during planned highway works, according to Buckinghamshire Highways.
The closure affects the stretch between Oakfield Road and Henry Road and is expected to remain in place until 6am on Saturday, 23 May.
Highways officials said the sinkhole developed during the initial phase of scheduled works after a “localised failure beneath the carriageway” was discovered. Further investigations revealed additional remediation work is needed before the road can safely reopen.
Specialist surveys are now being carried out, followed by excavation and full reinstatement of the damaged section of road.
Despite the closure, access for residents is being maintained from either side of the affected area.
Buckinghamshire Highways said it is aiming to reopen the road by Saturday morning but warned that updates would be provided if the situation changes.

The closure is also believed to be contributing to heavier traffic than normal on surrounding routes, particularly along Tring Road, Broughton Lane over the bridge, Bellingham Way and through Bierton on the A418, especially during the busy morning and afternoon school runs and rush hours as drivers seek alternative routes..
