Overnight road closures on some of the county’s key A-roads for resurfacing work have been confirmed for the next two months.

Suffolk Highways last week confirmed it plans to treat 150-miles of the county’s roads across more than 170 sites for its programme running from now until the end of August.

The programme includes road resurfacing – where the old surface is either overlaid or removed to a certain depth and a new surface applied – or surface dressing where the existing road surface is sealed and improved.

Portions of the county’s main A-road routes have been confirmed for May and June, with dates and diversions now lined up.

Suffolk Highways said the schemes will be overnight road closures to limit disruption as much as possible, with working hours for each scheme varying between 7pm and 6am.

A spokesman said: “Surface treatments are very weather dependent and may be subject to change so for all updates, I would suggest regularly checking One.Network for further details including diversion routes. Prior to some of these works, there may be the requirement to carry out surface dressing preparations.”

Outlined below are planned dates and locations of works on the Suffolk Highways-managed routes. The A14 is managed by National Highways and is not included here.

A12

The A12 Main Road at Kelsale-cum-Carlton (from Town Farm Lane to Main Road) and the A12 Main Road at Yoxford between Main Road and Brook Street will be surface-dressed.

Preparation work is planned from May 12-14, surface dressing from May 18-20, and road markings and road studs work from May 23-28.

Following that, five other portions of the A12 will be in line for full resurfacing.

The A12 at Woodbridge will be resurfaced from May 24-27, A12 Melton from May 30-June 7, A12 Benhall from June 8-10, A12 Blythburgh on June 10 and A12 Brightwell from June 20-24.
