We are in Rouen Sud at the Novotel. Re. The bridge being shut, the signs for the diversion are really easy to miss. Basically you need to come off the A28 in the direction of Dieppe. I just about spotted it as I had my eyes peeled. But Dh decided he did not believe me and kept going. Our sat nav picked up the closed bridge just as we arrived at it. I looked smug whilst Dh navigated the horrendous jam of traffic. I do not recommend this as a course of action.
