When's the roadworks M1 going to be finished

On a somewhat smaller scale, I regularly drive up and down the A327 from Reading to Farnborough and back, and they’ve built a new bypass round a village called Shinfield, just outside Reading. They also built a new bridge over the M4 and a big one-way system. That’s all open, but the bypass isn’t. It’s been sitting there for months while other work (I heard drainage mentioned) has been going on.

They’ve painted over the opening date on the signs at each end; it was meant to be late last year, then Spring this year, and both those dates have come and gone.
