A483 J5-7 Crossover Improvements (FAQS)


The works will include increasing the length of two central reserve crossovers together with drainage and barrier upgrades.

The existing surfacing in this location is in an extremely poor state and will require replacing later this year. When that happens, in order to carry out this work as quickly and as safely as possible, traffic will be placed into a contraflow situation using the crossovers in the central reserve. These crossovers have therefore been assessed by our designers and we will now need to upgrade them to make them safe for use when required.

It was not possible to deliver this project earlier in the year due to other essential works to renew the joints at Ceiriog Viaduct and planned roadworks by Highways England close to the border.

Failure to complete these works now would mean improved traffic management arrangements would not be ready in time for essential resurfacing works. This would necessitate full closures of the A483 and cause significant disruption in the future.

The work commences on 1/6/21 and lasts for 6 weeks.

In order to install temporary safety barriers to protect the workforce and to place the traffic management system there will be the need to close the A483 overnight for 4 nights at the start of the scheme and another 4 nights at the end.

These full closure have been limited to take place over 8 nights in total to reduce disruption as much as possible.

For works between Junction 5 and 6, Northbound traffic will leave the A483 at Junction 5 (the Mold road interchange) and follow the A541 to the A5152 and then to Junction 6 (the Gresford Interchange) where they will rejoin the A483. Southbound traffic will leave the A483 at Junction 6 and follow the A5152 to the A541 and then to junction 5 to rejoin the A483.

For works between Junction 6 and 7, Northbound traffic will leave the A483 at Junction 6 and follow the B5445 to the B5102 and then to Junction 7 (Rosset interchange) and rejoin the A483. Southbound traffic will leave the A483 at Junction 7 and follow the B5102 to the B5445 and then to Junction 6 to rejoin the A483.

The routes will be fully signed and patrolled.

The main works will be undertaken with traffic running in lane 1 in both directions for the duration of the scheme. There will be a 50 mph speed restriction in place while the lane 2 closures are in place.

These measures are necessary to protect the workforce that will be working close to live traffic as well as the travelling public.

Unfortunately, there will be some noise associated with the installation of the temporary safety barriers at night. However, the bulk of the works will be undertaken during the day and early evening and should be no louder than the normal traffic noise.

Temporary signs will be used on the diversion route to calm traffic and reduce the risk of traffic incidents which will in turn reduce potential delays and disruption. Traffic will be monitored on the diversion route so that any problems can be identified and addressed as quickly as possible.

Progress updates will be issued via Twitter @TrafficWalesN. This channel will also advise road users about congestion and expected journey times.
