Definetly not #3 or #4.
Anyway, yeah, these situations are lousy. Get a cross bike with some 700x32s or 35 HP slicks on it, ain't scard of a little dirt or gravel for option #5.
I'd also try taking the laneish for options combo #1 and#2, if traffic was not too agressive or heavy. I've ridden long stretches like that and it is uncomfortable unless you get a patient driver behind you willing to ride it out thru the zone..... how long is the construction anyways?
You can make your bike look MORE like a slow moving vehicle, by attaching a safety triangle on it. (Add a High vis ANSI class 2 or 3 safety vest and couple of Superflashes, you'll wind up looking like a low powered street sweeper or one of the construction crew doing something important!) I'd recommend a safety triangle jiggered off a spoke attached to your rack to the left.
you could also look at the detour as your chance to do a little more hill work while exercising option #6.
(Boy, i can't help but wonder if Serge or John F.'s influences had anything on this being enough 'accomodation' in construction zones for bicyclists, I remember Serge going on and on about him 'taking the lane uphill in a construction zone.....')
