Seven cars were damaged by one pothole early on January 14, causing the police to close part of the southbound carriageway at the Quarry Hill junction.
A seven-mile stretch of the dual carriageway was due to be shut in both directions for four days from January 8-13, so that Highways England could carry out repairs.
A year ago, issues were identified with the structure of the Medway Viaduct flyover above Haysden, as well as the Manor Farm subway near Leigh.
The surface of the bypass was breaking up due to problems with the movement joints in the viaduct, and Highways England said resurfacing the road would not solve the problem.
All traffic was to be diverted through Tonbridge town centre, causing chaos on the local road network, but these works were postponed because of supply chain issues.
Negotiations are ongoing between Highways England, Kent County Council [KCC] and Tonbridge & Malling Borough Council [TMBC] to find a date when the work can be carried out.
There had been criticism from local MP Tom Tugendhat and TMBC Leader Cllr Nicolas Heslop about the timing of the proposed repairs during school term time and the lack of notice the authorities received.
Highways England told the Times: “There has been no update as yet. But we are talking to KCC and other stakeholders including the local authority to determine the best time to do the work. Once everyone is happy we will let everyone know.”
A TMBC spokesman said: “The works are being led by Highways England and KCC as the highways authority in Kent.
“We have met with Highways England and are being kept informed but are not actively involved in delivering the works or managing the diversion of traffic.”
