Hi, I just read Bob Strasenic's note on the intersection closing.  I also contacted Mora yesterday - I think she contacted several of us in the late afternoon Bob.

Yes, the intersection will be open all weekend.  The work will be done Friday 7am-5pm, and also on Monday, same times. 

The detour will be routed through the Park, to come out on One Wild Place at the junction where the mosaic wall starts (below the Bunkerhill intersection).

I do have some concerns - the original plan was to have the intersection closed for 3 consecutive days, with round-the-clock work.  I'm waiting to hear back from Mora on how that amount of work could be done in two days.

Also she clarified, new for me, that the detour decisions, including routes and signage, and also timing decisions for road closures, are decided by DOMI.
