Questions concerning A34 wanted

My weekly runs are from Salisbury to Oxfordshire, I spend my time either avoiding the A34 or sitting on it praying there isn’t an accident. Coupled with the constant overnight closures and lay by closures making it difficult to get a break, it’s getting beyond a joke. Something needs to be done either build a new one, flatten out the roller coaster and traffic light the on ramps. But to many accidents now.
