In Santa Barbara we would have had some members of the coalition attending the planning meetings prior to construction to ensure that cyclist mobility was not impaired. And when the inevitable impairments were installed, those same members would be causing a stink with the city and construction company until things were rectified. There is no reason they cannot move the barriers over so that there is a bit more room in the outside lane.
I would not do option #3 because the construction guys will chase you out anyway. I think the only viable option on your list is to use the right lane however you feel comfortable #1 or if that turns out to be a hassle, #6 - the detour. The detour actually sounds like it would be a pleasant extra workout for the time being.
