Yes, two way traffic is coming. This has been in the plans for years. There are lay-bys built in for people to pull over.Currently when you look at the street markings it looks like one big one way street. I guess it will eventually be turned back to two way. One lane in each direction. Better hope nobody stops illegally or breaks down or the entire Queens Quay grinds to a halt.
They tried this out as a pilot project a few years back and it worked well -- that's one of the reasons they went ahead with this major undertaking. I was living on QQ at the time, and I loved it. I'm looking forward to seeing this all done, it's been a long time coming.
Like anything new, there will be some adjustment.
