I don’t know anything about the concrete central barriers…other than they are popping up everywhere, but the old Armco (?) metal ones were designed to give and gradually return you to the driving lane (with a ****ed up car, but at least safer for you)Driven the thick end of 500 miles the last 2 days and as I sat in traffic on motorways a thought came to mind... A) how the **** has one bridge over the A1 near Wentrbridge taken the best part of 2 and a half years to repair, when it would surely have been quicker, less expensive and have a lesser effect economically to thiose stuck day after day there to demolish the ****ing thing and replace it with one that wouldn't go tits..... and b) what sort of money is being spent on replacing all the central barriers up and down the country with the concrete versions. Who is getting the back handers and what effect has that had economically, loss of earnings etc. Surely, when we are cash strapped, spending money on road infrastructure and replacing central barriers has to go on the back burner... I'm sure people do hit them but dont they still do their job...?
How are the new ones designed to work?
EDIT - They’re Jersey barriers apparently (although aren’t made of wool) and last longer than metal ones.
