A55 Junction with A494 and A548 – Deeside Corridor Consultation A55 Junction with A494 and A548 – Deeside Corridor Consultation

The following is from Flintshire County Council

We are looking to improve journey time between the River Dee and Northop Interchange. We are carrying out a study to appraise two route options.


Project Status: Planned
Region/County: North East Wales
Cost: £200m, dependant on chosen route
Design Consultants: AECOM and Richards, Moorhead & Laing Ltd

Why We Are Doing It

The A494/A55 between the River Dee and Northop Interchange is a dual 2-lane road. It experiences congestion frequently.

The road experiences more traffic than it was designed for, and is below modern standards. It is poorly aligned and there is nowhere for broken down vehicles to pull off the road. Some of the junctions have slip roads that are too short or too close to the road, some of which have poor visibility. It is at these junctions that the majority of accidents occur.

The aims of the scheme are to:

  • improve capacity, reliability and journey times
  • improve safety
  • improve connections for businesses
  • improve access between residential areas and places of employment
  • reduce carbon emissions along the road
  • make more efficient use of the existing transport infrastructure

We will minimize the impact of these improvements on local residents, the landscape, air quality, biodiversity and pollution.

Current Progress

We have appointed AECOM, supported by Richards, Moorhead & Laing Ltd, to study the possible routes. We are undertaking environmental and engineering surveys. We held public information exhibitions between 15th and 18th September 2015.

The Plan

We are assessing two options. One is a package of improvements on the existing A55/A494, the second a series of improvements over Flintshire Bridge along the A548 and a new link to the A55 at Northop.


Route Selection Appraisal Early 2017
Public Consultation Spring 2017
Preferred Route Announced Summer 2017

How We Are Consulting

We held public information exhibitions in September 2015. We will be undertaking a public consultation during spring/summer 2017.

Next Steps

We are undertaking a WelTAG Stage 2 assessment which will be completed in 2016. This will enable us to assess the two route options in preparation for public consultation.

A decision on the preferred route will be made in 2017.
