Road users will benefit from new concrete safety barriers being installed on the central reservation of the M5 near Weston-super-Mare.
The work, which begins on April 4, will involve the replacement of four miles of worn out steel barriers with a concrete system.
Narrow lanes and a temporary 50mph speed limit will be in operation in the area while the work is being carried out.
Highways Agency manager, Dave Sledge, said:
“Concrete barriers reduce the risk of vehicles involved in accidents crossing from one side of the motorway to the other, with the additional disruption that causes, and improve safety for road users and road workers. They also last longer than traditional steel barriers.
The work has been carefully planned and where possible, will be lifted during busy Bank Holiday periods. We would remind all drivers to pay extra attention while driving through road works and observe all speed limits which are there for everyone’s safety.”
