Don’t think he’ll know unless he has a crystal ball. I live locally as I’ve said before, and it changes weekly and without warning. Keep your fingers crossed is my advice.
They’re building a huge bridge right outside the Stoneleigh exit, which I presume is to allow HS2 to go underneath the reworked roadway and through the northern section on the showground. One week the road is open, the next week it’s closed. What I do know is that there’s no signs warning you it’s closed until you’re almost on top of it and you have to make a 3-point turn on a B-road.
HS2 around here is pretty much a law unto themselves. The road between Leamington and Southam was supposed to be replaced with a temporary road right up until a fortnight before tunneling work began, then HS2 said it wasn’t possible (cost - yeah, right) and shut the road for 18 months requiring a 10 mile diversion.
