Much prefer that route to be honest, and 3.15 is decent enough progress.
Used to use the 361 regularly for the car storage compounds at Chipping Warden, horrible road at the best of times.
dozy:
Tesco give you risk assessments with the route you must follow , don’t start taking any notice of some random driver off heres route or start thinking for yourself , or Tesco won’t be employing you for long
What do you do then? Just sit and wait at the cones for six hours until they lift them? 
Edit: From my personal experience I’ve never had any questions about which way I’ve gone whether that be because of closures or just because I fancy a change of scenery from time to time.
