I did this last year and, although the path was washed out, it was easy enough to push a heavy bike and gear under the bridge and back onto the path. I found the path from the village (!) to the bridge was iffy in places, due to the breakdown of the paving and the deep sand. Doable on 35mm tyres but still a push in places.
On the up side, it’s only a short stretch of a couple of hundred metres or so.
