Slight problem - Roadworks.org say the restriction is one-way only, but doesn’t say which direction! (I think you may need an extra option ticked to see one-way restrictions)
A one way restriction would seem to be compatible with the stated reason for the works - "footway works - which might mean one side of the road is closed at any time to provide working room for the side being done.
OK. The signs you saw said “5 days”. Roadworks.org says “30/11 - 6/12”. Since that’s seven days, I think it’s reasonable to assume the road will be open at the weekend. Also, given that it’s footway works, I’m guessing the road will only be closed when they are actually working on it.
So I’ve closed it Weds, Thurs, Fri, Mon, Tue; 8am-6pm; SE direction.
