Motorway barriers need upgrade before speed limit change happens, says concrete expert

Concrete paving association Britpave director David Jones has warned that many motorway central reservation barriers may not be fit-for-purpose if the speed limit is increased to 129km/h (80mph).

Transport secretary Philip Hammond has proposed raising the speed limit by 2013. Jones said in a statement that this should only be done if the government first ensures that motorway barriers are fully able to accommodate the safety issues that come with increased speeds.

“There is a clear need to upgrade the existing barriers on our motorways, most of which are only designed to contain a medium-sized car,” said Jones. “Many miles of barrier are now rusted, and no longer fit for purpose. Let’s hope the government sees sense and includes a barrier upgrade program as part of the … speed increase package.”

Concrete barriers can contain all vehicles up to and including coaches weighing 13t and would prevent most crossover accidents, but are currently used on just 10% of the UK motorway network, Jones said.
