From what I see, where there is a lack of dedicated lanes the roads are typically quite narrow--very little room for expansion for even a single dedicated lane (aside from the two lanes of regular traffic).
One section of the route is wide enough, but iirc, the residents along this particular segment in Provo fought against the dedicated lane (and won, afaik).
