Story updated on Friday, August 14: A temporary 30mph speed limit is to be introduced on the A22 Uckfield by-pass from Monday (August 17) as works progress on a roundabout to serve the Ridgewood Farm housing development.
The speed limit is expected to be in place for the seven month duration of the roadworks and traffic lights will be in place for about three weeks from Monday, between 9.30am and 4pm.
The existing lay-by will be permanently closed from the same day with advance warning signs notifying users.
The work to install a new roundabout will be carried out in phases, with completion due by February 2021.
For the second phase the road will be subject to a series of overnight closures.
Cllr Claire Dowling, East Sussex County Council lead member for transport and environment, said: “This work is being carried out not by the county council, but by Mildren Construction on behalf of the developer.
“However, it will have an impact on our roads and therefore we will be monitoring the scheme as it progresses, to ensure all works are to the required standard.
“We will also work with the developer and contractor to ensure any disruption to motorists and local residents is kept to an absolute minimum.”
During the first phase, due to last for three weeks, traffic will be reduced to one lane between 9.30am and 4pm Monday to Friday, with two-way traffic lights in place.
The second phase of traffic management, from September to February 2021, will see traffic flowing in both directions but with narrowed lanes.
From September to December, the narrow lanes will remain in place and a series of night time closures will happen from 8pm to 5am, with the A22 closed and traffic diverted via Uckfield town centre.
Overnight closures will be timed to avoid late night shopping and any other events in the town centre in the run-up to Christmas. Signs will be in place on the A22 to advise motorists before and during the work.
The new roundabout is being funded by the developer.
The county council says that at present, it’s not anticipated that the ongoing coronavirus pandemic will have any impact on the scheme, but any changes will be notified via social media or on the East Sussex Highways website.
