Work to introduce a 60mph speed limit across the Orwell Bridge will begin on November 30.

Highways England has confirmed the work, including improved road markings and signs as well as average speed cameras on the stretch of the A14, will take place mostly overnight.

There will be some overnight lane closures from November 23 in preparation for the works, and the scheme is due to be completed by the end of February next year.

Most of the work will be carried out overnight, involving lane closures between junctions 56 to 57, with some minor work taking place on the verges during the day.

The westbound slip road at junction 56 will be closed overnight, from 8pm until 6am, and traffic will be diverted to junction 55 and re-join the A14 eastbound to exit at junction 56. More details including dates will be announced closer to the time of the works.

The work is dependent on suitable weather conditions, and dates may be subject to change.

Some full road closures will be needed towards the end of the work.

Aran Nugent, service delivery team leader at Highways England, said: “The A14 at Orwell Bridge is a vital route and we are committed to improving safety and reliability for the thousands of drivers who depend on it every day. This is why we will be reducing the speed limit to 60mph.

“We have planned this work carefully to minimise the inconvenience to road users, by carrying out work overnight when traffic flows are lowest, and will suspend work during the Christmas period, but I would urge motorists to plan ahead and allow extra time in case of any delays.”
