Major Resurfacing Works on the A483 south of Junction 7 (Rossett Interchange) and the Wales/England border.
The works involve:
• removing the worn-out surfacing,
• repairing and/or replacing the underlying concrete slabs
• resurfacing with an improved surfacing product
The works are required as the road surface has reached the end of its serviceable life.
Once repairs are complete, the new surfacing will have none of the existing transverse joints which cause unacceptable amounts of noise when driven over by cars.
The work will also significantly reduce any unplanned closures for emergency repairs on this section of the A483.
The work commences on 05/02/23 and lasts for 9 weeks.
In order to achieve this programme, the contractor will work in shifts enabling a 24/7 working schedule.
The repair and/or replacement of several concrete slabs, together with the laying of 2 layers of surfacing, will require full closure of each side of the dual carriageway in turn.
Therefore, a contraflow arrangement will be set up which will allow the A483 to remain open to one lane of traffic in either direction.
These measures are necessary to protect both the workforce and the travelling public, and to enable the works to be carried out in as short a time as possible.
There will be full overnight closures at certain times within the programme to enable the installation and dismantling of the temporary traffic management system required to undertake the works.
There will also be full overnight closures at the end of the programme as well to enable repairs and resurfacing within the crossover area.
There will be daytime lane closures at certain times to facilitate the installation of the contraflow and to enable repairs and resurfacing within the crossover areas.
For overnight road closures between Junctions 6 and 8, northbound traffic will leave the A483 at Junction 6 (Gresford Interchange) and follow the B5445 to Belgrave junction, where they will re-join the A483.
Southbound traffic will leave the A483 at Belgrave junction and follow the B5445 to Junction 6 (Gresford Interchange), to re-join the A483.
The routes will be fully signed and patrolled.
In order to complete these works in such a short period of time, there will be overnight working.
However, we are working with the contractor to identify the noisiest activities of the works and programme them to be carried out during the day and early evening.
The majority of the work operations will be no louder than the normal noise associated with traffic using the dual carriageway on a daily basis.
We have been working on major repairs and upgrades to the concrete carriageways in general on the A55 and A483 in the last few years.
There are only some windows of opportunity to carry out these works without affecting the higher traffic flows in the summer and avoiding the issues experienced during the colder winter months when surfacing cannot set properly.
This time is therefore a suitable opportunity to undertake the works.
When the contraflow is in operation certain slip roads will be inaccessible.
Drivers will follow diversion signs along the A483 to one of the other interchanges in order to continue their journey.
Traffic will not be diverted away from the A483 during the contraflow operation.
Mitigation measures will be in place, and we will be working closely with Wrexham County Borough Council and Cheshire West and Chester Council’s highways departments to monitor the situation.
Completing these works at the same time as the J6-7 resurfacing would have required a very long traffic management setup, which would have meant closing J6 (Gresford) and J7 (Rossett) at the same time.
Splitting the works into two phases will reduce the impact on the local road networks.
The length of the traffic management is governed by the location of the existing crossovers and the subsequent position of the safe taper position (i.e. where two lanes are merged into one lane).
Due to the alignment and visibility of the road, a longer traffic management length is needed to safely merge two lanes into one.
