Part of Gedling Access Road will shut for one night this week while Nottinghamshire County Council repairs damage to the road.
The damage was discovered last month on December 22 – nine months to the day since the road’s March 22 opening.
The hole was found just after the second roundabout when travelling southeast.
This section of the road will be closed overnight from 7 pm on Wednesday (January 11) until 5 am on Thursday, with the closure stretching to the junction with Lambley Lane.
The £49m road, officially named Colliery Way, was constructed after decades of campaigning to ease traffic and congestion through Gedling village.
It was initially due to open in autumn 2021 and was budgeted at £40m but price increases fuelled by the pandemic pushed the project back and costs up.
The Conservative-led county authority said the pothole was part of wider damage to the road surface and was caused by “badly-fitted farm machinery”.
Taxpayers will not foot the bill to repair the road, because the council is currently in a warranty agreement with its contractor Balfour Beatty.
The hole has since been filled with temporary asphalt solution ‘Viafix’ and the works this week will be a more permanent repair to the road.
Last month, Gary Wood, head of highways and transport at the council said: “We are already aware of some damage to Colliery Way caused by badly-fitted farm machinery.
“This latest damage will be investigated to ascertain the cause.
“The road is still under warranty with Balfour Beatty which will carry out any permanent repair required at no cost to the council.
“In the meantime, the road has been made safe and will remain under review.”
