Its seems ludicrous to me ! What if you have an breakdown, like a puncture ?
If you were stopped on the hard shoulder, trying to fix it, would you cause another accident, to the traffic driving on the hard shoulder behind you ?
seems to have dramatically improved traffic flow on the M62 since it was completed around 3 months ago, so I think the 'feasibility' stage is long past.
it's been in use on the M42 for 7 years now. yes of course it's a cheap 'n nasty way of getting more capacity - however there's a nil possibility of millions being spent on a widening scheme or relief road until it's been tried and shown to be a failure.
great because cars all know not to break down unless by a "refuge bay"! I know let's join all the refuge bays together and make a hard hard shoulder! hang on!
And there it is. Why finance a job properly if you can get away with a cheap workaround that only conveniences some, some of the time. Second rate wins the day.
So whats the difference to driving on a dual carriageway or even a 60mph single carriageway road? The lanes are not permanently hard shoulders, they only become so when traffic is heavy and then the speed limits are less than 70 (often 40 and 50).
it's not just cost, OG - there's environmental factors to consider too, particularly when those sections of motorway that need it most are not conveniently adjacent to space to grow into.
