Introduction to the A55 Road
The A55, also known as the North Wales Expressway, is a critical artery that connects Cheshire and North Wales. Being a primary route, the A55 is often bustling with traffic, with certain sections particularly prone to congestion, especially during peak hours.
Key Features of the A55
The A55 stands out for its unique characteristics, making it a vital part of the regional transport network. All junctions are grade separated from a roundabout east of Penmaenmawr and another nearby Llanfairfechan. The road originally ran from Chester to Bangor. Still, in 2001, it was extended across Anglesey to the ferry port of Holyhead, forming an integral part of Euroroute E22 under the Trans-European Networks programme.

Busiest Sections and Junctions
Starting at junction 12 of the M53, near Chester, the A55 traverses various towns and junctions, some busier than others. The section between J39 Christleton and J36a Broughton, known as the Chester southerly bypass, sees significant traffic, especially during rush hours.
Another critical point is Junction 34/33b, where the A494 converges and diverges with the A55. This junction often experiences heavy traffic and can lead to delays.
The stretch between Northop and Halkyn (Junctions 33 and 32b) and Halkyn and Holywell Summit (Junctions 32 and 31) is also prone to congestion. This section of the road, which passes through the Halkyn Mountain range, is notorious for poor weather conditions, causing delays, particularly during winter.

Speed Limits and Traffic Regulations
The A55 features varying speed limits that drivers need to be aware of. For instance, two road sections, from (Junction 23) Llanddulas to (Junction 17) Conwy, carry a 70 mph speed limit and often see high traffic volumes.
On the other hand, the Colwyn Bay bypass (Old Colwyn to Mochdre) has a 50 mph speed limit due to its unusually short slip-roads. Despite being a point of contention among drivers, this limit was implemented as a safety precaution and to reduce road noise for residents.
