I didn't see your modification, I'm fine with living street too.

Sorry for the late reply, I have been again there last month. It was open again for cars.
There is a direction sign for Le Lude. Residential feels a bit weird to me as it is the road used (when opened) to go to Le Lude when coming from the south of the city.
But reading the wiki I guess residential is the best match.

There are flower pots and big cement blocks blocking the road with a "sens interdit" sign attached to it. The terrace of the cafe uses the road.
It looked permanent to me, but checking the internet it seems to be only half of the year. I could not find a precise schedule though.
