The current closure is currently stated to re-open right on the cusp of the time frame. The problem that is that not all mapping software is quick to pickup updates and make changes via OSM. This section of the road is very well marked by the City of Vancouver as I drive it daily. There are signs noting which roads to take as detours, how long the road will be closed, and where to drive along to get where you are going. The road still exists and you can also traverse for local traffic through the corridor on smaller sections.
