Traffic signals will help manage congestion on the off slips, reducing the length of queues and the traffic speed to improve safety on the roundabout
It is hoped the newly implemented traffic signals will help manage congestion on the off slips, reduce the length of queues, speed of traffic and improve safety on the roundabout.
A Welsh Government spokesperson said: “Work is progressing well at the Junction 19 interchange which will improve safety and will be a boost for active travel.
"Most of the drainage and ducting work on the main roundabout and embankment has been completed, and work on the footpath has begun.
"Temporary traffic signals are now in place, with plans for permanent traffic signals as part of the scheme."
The works will also see the junction widened and the construction of safer crossings for pedestrians and cyclists.
Street lighting will also be upgraded to an energy-efficient LED alternative.
The work would originally have been carried out after the summer but due to Covid, traffic levels dropped on the A55 to almost half their normal levels.
This allowed the Welsh Government to start work earlier than intended. ref Pioneer
