Thanks. The water at the Great Brook bridge in the pic was flowing quickly still. You can just make out the road closed sign in the pic, and from here the road to TadpoleB looked fine; but, from what I could see it was the other end near the bridge that was totally underwater. Tubney underpass was more or less dry, unlike 2 Jan when I went through about foot of water.
On the Yelford road from A415 to Cote, only met one car; but had the obligatory don't-ride-two-abreast 'reprimand' hooter, on a wide, straight, and clear section of B-road...
