Overnight safety work to repair a section of the westbound A14 in Suffolk before winter will start on Monday.
The work will be carried out on a two-mile section on the westbound carriageway only between junction 49 (Tothill Interchange, near Stowmarket) and junction 47a (Woolpit/Elmswell Interchange).
It will take place over 10 nights, Monday to Friday only.
Ranjit Mistry, Highways Agency project sponsor, said: “Safety is our top priority. The A14 between Stowmarket and Bury St Edmunds needs urgent surface repairs to fill the cracks and joints before the winter to ensure our safety standards are maintained.
“We looked at a number of different options for how to minimise disruption during this essential work, including a contraflow system. We concluded however that the most efficient and quickest way to carry out this work is by closing the carriageway overnight when traffic flows are at their lowest.
“We are aware there are local concerns about the diversion route. We would like to reassure those people that the diversion route we will put in place for through traffic will be clearly signed and is designed to direct drivers who do not know the area onto the most suitable roads. There will be an alternative route, for heavy vehicles coming from Felixstowe and Ipswich, to use the A120 trunk road and the M11..Again this will be clearly signed well ahead of the work,
“The diversion for through traffic will add about 20 miles to drivers’ journeys and we ask that drivers affected by it allow extra time for their journey and take extra care when travelling along the route.”
The westbound carriageway only will be closed overnight between 8pm and 6am, Mondays to Thursdays, and between 8pm and 10am on Friday nights, a total of 10 nights. The work is due to be completed by Saturday 22 October, weather permitting.
Through traffic travelling westbound will be diverted off the A14 at junction 51 (Beacon Hill Interchange) via the A140 to Diss and then the A143 westbound where it will rejoin the A14 at junction 43 near Bury St Edmunds. There will be local access only from junction 49a.
Heavy vehicles will be directed to use the A12, A120 trunk road and the M11 instead of the A14.
