Well, 'plans' eh?
How many times have we heard that?
Warwick, not Warwickshire Uni. But I'll let you off, hehe.
HS2 are building a new road that does indeed circle round South of the site, and I believe it is intended that the current junction on the A46 bypass will be made much bigger to cope. I think the road is intended to provide a more effective southern bypass for Coventry out to the M42.
With the way Warwick District Council are on delaying any plans just for the fun of it, they will be lucky to see it done in 10 years, if they plan to disturb the habitat of even a single worm.
