HERTFORDSHIRE’s main roads had to be salted three times over night following heavy snowfall.

Between last night and this morning (Friday) Hertfordshire Highway’s gritters went out at 8pm, 10.30pm and 2.30am, in an attempt to keep roads safe for motorists.

But it still couldn’t stop the snow causing havoc to schools and public services.

Several schools in Welwyn Hatfield have been forced to close due to the weather, and the borough’s refuse and recycling rounds have also been cancelled.

And Welwyn Hatfield Council’s chief executive Michel Saminaden even delivered food to 15 residents who would usually receive the vital meals on wheels service in his own 4x4.

County councillor Stuart Pile, executive member for highways, transport and rural affairs, said: “We’ve been working hard to keep main routes clear for the morning rush hour although we are aware of travel problems in areas where the snow has been heavy.

“We advise residents to travel only if your journey is essential. If you do decide to travel, please check local travel news first and allow extra time for your journey.”

Hertfordshire Constabulary will be updating its website and putting out information about road closures and areas where there are delays.
