Here are some pictures from today showing the 9A Street NW bike lane closure.
The construction fencing is only over a limited area but clearly blocks the bike lane. There was no obvious signage indicating a detour.
Maybe it's not too big a deal since everyone seems to just walk or bike wherever they need to on this block. Also, traffic moves pretty slow.
It would be nice to see a proper solution that accomodates cyclists though.
I did look over towards the east platform and the sidewalk running up that side looked to be closed off as well. I didn't actually go over and check.
