More than 4,500 solar road studs have been introduced to the route as part of a £8.5 million worth of improvements to journeys along the route, which is used by more than 23,000 vehicles every day.
Upgrades include high visibility lane markings that make it easier for drivers at night or in adverse weather conditions, and coloured high friction surface that reduces the risk of skidding. In addition, the road studs are also effective in heavy rain, mist or fog and a four-hour charge from daylight can power the devices for over 200 hours.

Highways England project manager, Matthew Carruthers, said: "We're always looking for new ways to further improve journeys and safety for drivers and this is a great example of that.
"This section of carriageway has no street lighting so the solar road studs and improved lane markings make a real difference.
"At the same time the new technology is more durable, meaning less disruption for motorists in the long term thanks to fewer roadworks."
