Hello Terry!
After reading all these chapters I simply had to write some feedback! The time this story starts in reminded me heavily of Smallville, the 'Superman-to-be'-show. Initially, because of that, I was prepared to hate Lana at first sight. But you know what? I so didn't expect to like her even after having finished the first chapter and I found a situation in the second chapter hilarious (I'm talking about her hanging on Clark's every word as he tells about his background), then morphing into serious with lots of humorous freckles (an artificial intelligence called Bob, rofl).
As the chapters wore on there were more and more incidents to discover Lana's train of thought and not (yet) considered plans. There were lots of passages which warranted certain concern about Lana - from the beginning you did a good job in portraying the mostly hidden struggle of a child trying not to become one's mother but at the same time valuing similar goals - and I enjoyed the way, you tried to resolve them.
Bringing Lois in the plot was unexpected as well because you took a great deal of time with that. In the beginning she was no more than mere support cast to the whole marriage-plot and their first two encounters were underlined by a (steely) determination, lacking fiery passion I surely expected.
In the end, I still don't know where this story will lead to - and there are only 2 chapters left! Being unpredictable is great, but I also fear that you won't be able to send an appropriate message in such a short time with so much stuff still untold. The greatest surprise in the final chapters was Lana telling Lois about Clark - why? They hated each other and just one moment of companionship cannot possibly be the cause for revealing this secret. Leaving Lana to die could be one simple way out of this mess (I remember Bob predicting mortal death likelihoods) but then, I would expect a sequel as well.
Anyways, I'm looking forward to the final chapters of The Road Taken, and if I haven't already said so: this story of yours is a phantastic alternative universe, one I'd trade with Smallville any day (sorry, maybe not that much of a compliment).
