Coeval is very pleased to announce their success in their bid to supply 4 no. 4 X 15 mobile Variable Message Signs (VMS) to increase the resilience of the ever-busy A55 Trunk Road traffic network.
The A55 is the primary east-west route through North Wales, running between Chester and Holyhead. It is the main economic route from the motorway network in the north west of England across North Wales, and onwards by ferry to Ireland. The road is some 81 miles in length, with several major and minor junctions, and carries 43,000 vehicles a day; it allows traffic to bypass towns and villages whilst providing easy access to the coastal resorts in North Wales.
These new mobile VMS signs will be deployed along the A55 and controlled remotely by Regional Traffic Control Centre (RTCC) in Conwy. Using 3G or 4G technology, messages can be swiftly changed depending on the change of circumstances to the road conditions.
The hardware comprises of a 20-foot-long mobile road trailer holding a large (4.4m x 2.2m) 4×15 mobile VMS sign, fully compatible with the RTCC in-station System. The nature of this bespoke project meant the trailers had to be designed and constructed from scratch; this guaranteed the signs could be perfectly fixed in position. The sign dimensions and weight were carefully taken into consideration, allowing the hardware to work effectively as one unit.
The trailer contains a built-in hydraulic mast that enables the sign to reach a further 2.5 metres into the air. This allows the signs to overlook any objects like road-side bushes, trees or barriers. The mast can also be fully rotated, adding greater flexibility to the sign itself and its utility.
The four mobile VMS trailers have been delivered, with the first sign now being successfully deployed. It is now providing safety information to drivers along the route of the A55 near Wrexham.
As far as we are aware, these are the largest and longest mobile MVMS signs to have been produced and supplied so far in the UK – another great example of providing solutions through our process, with bespoke manufacturing and experienced signage engineers.

‘Even a short closure of the tunnel causes great congestion in the area, and if an over height vehicle were to cause that level of damage, the tunnel could be closed for hours, if not days, which would bring the whole of the South East of England to a standstill.
When the Coeval over height vehicle detectors were first installed, we were talking about 10’s of vehicles a day that we were stopping; we are now down to low single figures, 4 or 5 vehicles a day we need to extract for being over height, so it’s a great improvement in efficiency through the crossing.’
‘Having used Coeval for the first time, we found them to be friendly and really helpful in ensuring we received the correct item we required. We were happy with the extremely quick response times and professional service they offer. We would definitely recommend their services to others.’
‘Thank you for your prompt and efficient service regarding our request for training on the 21st of August. You guys have been incredibly helpful over this.’
‘Coeval won the tender for the replacement overheight vehicle detector systems. The work was completed within programme and budget. We are now satisfied that the new systems will help protect the bridges for several years to come.’
‘A sound, honest and efficient service provided by Coeval. Would be very happy for Coeval to manufacture and supply more of Swindon’s signs.’
