The nature of the carriageway failure and reasons for road closure at A26 Tonbridge Road, Maidstone

Following reports of a collapse and depression in the carriageway on the afternoon of the 28th May 2018, the A26 Tonbridge Road was attended by our local out of hours Highways teams to investigate the incident reported. While on site, a section of the carriageway surface collapsed to expose a deep void under the road, in addition the collapse continued to develop on site during our attendance. Due to the nature of the collapse and the infill within, we could not determine the full extents, or causes of, the void while on site. The road has been closed for the safety of local residents and all road users.

The A26 Tonbridge Road is closed at the junctions of Terminus Road and Fountain Lane. The primary diversion (suitable for all traffic & LGV's/HGV's) is via the A20 Terrace Road, A20 London Road, Ashton Way, A228 Malling Road, A26 Tonbridge Road (& Vice Versa)

A secondary diversion is available for vehicles under 7.5 tonnes only utilising Queens Road, A20 London Road and the B2246 Hermitage Lane/Fountain Lane

The current situation as of the 29/05/2018

The collapse on the A26 Tonbridge Road, Maidstone, adjacent to the Taj Barming Indian Restaurant, is both significant and severe with the collapse currently visible on site representing a larger void underneath the road. Our preliminary investigations suggest that this void extends either side of the road from kerb to kerb for a total distance of 20 metres. We will know more once investigations begin and resources are being mobilised as the highest priority and as soon as possible.

Please can we stress that as this is a main strategic route, numerous sub surface pipes and ducts for a multitude of utilities and high volume services, including gas, water and electricity, are present adjacent to/within the collapse. Significant liaison will be required with our utility partners (many of whom were mobilised yesterday evening to assist and check their assets) and significant care will be required when excavating the road to allow investigations and take the subgrade back to stable ground. This may impact on the timescales of works, in addition to other factors which may be identified as investigations progress. We will keep you up to date with further information as our investigations progress.
