Nacton Road, Ipswich roadworks

About the current and planned phase of roadworks and road closures for Nacton Road, Ipswich; and why the improvements are being made.

These roadworks will increase the traffic capacity of the junctions and links on the Nacton Road, Ransomes Way and Felixstowe Road corridors, reducing delays during peak traffic periods.

The works taking place include:

  • widening Nacton Road between The Havens and Thrasher roundabouts to provide 3 lanes for traffic
  • provide a left slip road at The Havens roundabout so traffic can travel onto the A14 eastbound slip road
  • provide 3 lanes for traffic on Ransomes Way
  • increase the capacity at the 3 roundabouts on Ransomes Way, by widening the roads in localised areas
  • improve cycle and pedestrian routes along these roads

Due to the size and complexity of this project, the work is being split into a number of phases.

Details of future phases of work are currently being finalised and will be published on here soon. This will include improvements around St Augustine's and the timings of these works.

Phase 2

April 2016

Suffolk Highways work on the second phase of the Nacton Road capacity improvement went well.

As the widening works progressed between The Havens and The Thrasher roundabout, it became apparent that some work was required to an underground UK Power Network electric cable.

After excavations took place, a cable was found to be closer to the road surface than our preparatory trial holes had suggested; and at a shallower depth than was shown on the plans we were provided with before works began.

The movement of this cable needed to happen before the widening could be completed, and meant that the outbound lane closure, and the night-time closure were altered to allow the cable to be diverted and lowered. These cable works took place on 13 and 14 April.

The 24-hour outbound road closure remained in operation until 22 April. The planned night-time road closure took place from 22 April, although the works took place over 5 working‑day nights (between 7pm and 5am, excluding weekends), rather than the original 3 nights.

During the period of closure, through traffic was diverted via A1189 Ransomes Way, A1156 Felixstowe Road, A12/A14 interchange (junction 58) and A14 and A1189 Nacton Road (junction 57). The resurfacing work happened around the remaining widening works, so temporary lining and traffic management were in operation.

Councillor James Finch, Cabinet Member for Highways and Transport, said:

"We have found a solution that enables us to work around this issue and to keep close to the agreed schedule, rather than having to cause further unnecessary delays."

Work to widen Nacton Road between The Thrasher and The Havens roundabouts to increase capacity went well. When the physical widening works took place, Nacton Road was closed in an out of town direction only (eastbound), from The Thrasher roundabout.

Following the physical widening, the road was resurfaced. This operation was undertaken at night by closing Nacton Road completely from The Thrasher to The Havens roundabout.

After the resurfacing was complete the road markings, traffic light sensors and road studs were reinstalled. Resurfacing and lining works took place overnight from 7:30pm to 5am.
