The A55 trunk road is the primary east-west route in North Wales and is the main economic artery from the motorway network in the north west of England across North Wales and onwards by ferry to Ireland. It forms part of the Trans-European Road Network route E22 (TERN Route) that links Holyhead with Russia and fringes the Snowdonia National Park and North Wales coastline. Locally, it allows traffic to bypass towns and villages yet provides the main access to the coastal resorts and administrative centres in North Wales.
The road is some 129km (81 miles) in length, carrying 43,000 vehicles a day (average daily 2006 figure for junction 33, Northop interchange) with several major and minor junctions.
It is a dual carriageway all purpose trunk road that has been constructed and upgraded from the late 1960’s through to present day under a number of major highway engineering projects, including the impressive Britannia Bridge and the A55 tunnels.
The Agency is responsible for assisting Welsh Government with the safe operation and efficient management of the road from Junction 11 near Bangor, through to the border with England near Junction 35a. In this respect it works closely with the local authorities, emergency services and other organisations such as VOSA. To help to effectively manage the road, NMWTRA employs a number of Route Stewards.
