Important roadworks information

Dear Sir/Madam,

A14 junction 50, Stowmarket to junction 52, Claydon in both directions: resurfacing 

Following on from previous communications, we are writing again to inform you of some changes to our works programme.

Changed dates are highlighted below.

We plan to complete this work over twelve weeks from Monday 11 May to Tuesday 4 August, on weeknights only, working between the hours of 8pm to 6am, subject to weather conditions.   Due to the extensive amount of work on this project, we have split the programme into three phases. We have closely liaised with county councillors and Suffolk Highways, to agree the most suitable diversion routes for each phase as detailed below:

Phase 1: A14 eastbound between junctions 50 to 51, starting Monday 11 May to Wednesday 24 June

– The closure point will be located at junction 43, Bury St Edmunds. Traffic will be diverted via the A143 and A140 to re-join the A14 at junction 51. This allows us to deliver additional maintenance works at junctions 43, 44 and junctions 47 to 50. (Diagram 1)

– A secondary closure point will start at junction 50, Stowmarket. Traffic will be diverted via the A1120 and A140. A four-way traffic light system will be installed at Earl Stonham to help filter traffic onto the A140, to re-join the A14 at junction 51. (Diagram 2)

Phase 2: A14 eastbound between junctions 51 to 52, starting Thursday 25 June to Friday 10 July

– The closure point will start at junction 51, Beacon Hill. Traffic will be diverted via Norwich Road, Barham and Ipswich Road, Claydon to re-join the A14 at junction 52. (Diagram 3)

On Monday 29 June the A14 junction 52 westbound entry slip road will be closed for one night, between 8pm and 6am, while survey works take place prior to the westbound works starting Monday 13 July.  Traffic will be diverted from junction 52 to join the A14 eastbound to junction 53, to re-join the A14 westbound. (Diagram 6)

Phase 3: A14 westbound between junctions 52 to 50 starting Monday 13 July to Tuesday 4 August

– A14 traffic: The closure will start at junction 52, Claydon. Traffic will be diverted via B1113 and A1120 to re-join the A14 at junction 50. Temporary traffic lights may be required to improve traffic flows along the route. (Diagram 4)

– A140 traffic: Traffic wishing to join the A140 northbound at junction 51 will be diverted via Ipswich Road, Claydon and Norwich Road, through Barham (Diagram 5). A140 southbound traffic wishing to join the A14 westbound will be pre-diverted at Earl Stonham to take the A1120, to join the A14 at junction 50.

Please be aware, during daytime hours there will be a temporary 40mph speed limit in place along the A14 between junctions 50 and 52 for safety reasons.
