FAQs A55 Junction 36 Warren Interchange - Wales/England border Major Resurfacing Works

The works are needed to:

  • remove of the worn-out surfacing, 
  • repair and/or replace of the concrete slabs under the road.
  • resurface with an improved surfacing product
  • replace the gulleys, manholes and a section of the vehicle restraint system.

The long-term benefits:

  • The new road surface will be quieter as the existing transverse joints will be removed.
  • The road will be safer.
  • Fewer unplanned closures for emergency repairs on this section of the A55.

Since January 2020, we have done about 98 temporary road repairs on this section. More than half of these repairs were done during the day with rolling roadblocks and overnight. Doing this work now will reduce daytime disruption from roadblocks and from overnight closure.

The main works will be carried out between 11th February and the 25th of March 2024 using:

  • daytime single lane closures 
  • overnight and weekend full closure utilising the local diversionary routes
  • eastbound carriageway being undertaken first followed by the Westbound. 

Before the main works, junction 36A Broughton Retail Park slip roads will be repaired and resurfaced utilising slip and lane closures between:

  • Weekend closure 26 January – 29 January junction 36A Broughton Retail Park Eastbound onslip and A55 lane closures
  • Overnight closure 29 January – 30 January junction 36A Broughton Retail Park Eastbound onslip and A55 lane closures
  • 2 February - 7 February junction 36A Broughton Retail Park Westbound offslip and A55 lane closures.

To achieve this programme, the contractor will work in shifts enabling a 24/7 working schedule. 

We will close one side of the road at a time (eastbound first, then westbound). This is to repair or replace the concrete slabs and put down 2 layers of new surfacing. We will close lanes from Monday to Friday between 06:00 and 20:00. We will close the road overnight from 20:00 to 06:00 on weekdays and close it from Friday 20:00 to Monday 06:00 on weekends.

We have worked closely with the local authority to ensure the most suitable diversions are used and to manage the routes throughout the works.

Diversions can be found on the roadworks page

There will be overnight working to complete these works as quickly as possible. We are collaborating with the contractor so that the noisiest tasks will be scheduled during the daytime and early evening. 

There will be overnight working to complete these works as quickly as possible. We are collaborating with the contractor to minimise the noisiest tasks to daytime and early evening however due to the nature and number of concrete repairs required to the carriageway some noisy operations will be required overnight.

We are working with the contractor to identify additional mitigation measures as well as programming any noisy operations near residential properties to a minimum however there will inevitably be disruption caused.

We considered using a contraflow system, but after studying the traffic patterns, we decided not to because it would be more dangerous and cause more disruption on the roads. During the construction, we will close the entire road in one direction at a time on weekends and overnight. This is better than using a contraflow, which would affect both directions for the entire duration of the project. 

We will also have daytime lane closures on weekdays to minimise disruption. This will allow one lane of traffic to flow freely when the road is busiest. We have scheduled full closures for overnight and at weekends when traffic is usually lower. 

The diversion route will have signs to guide drivers and will always be monitored.

The start of the traffic cones needs to be positioned before junction 35 Dobshill due to visibility, it is not safe to put the cones closer to the works area. This layout will help minimise the disruption when changing the traffic management from daytime lane closures to overnight closure.
 

This is to complete the works between the Wales/England border and junction 36A Broughton Retail Park. The tactical diversion has been agreed in advance with the local authorities and National Highways.
