If that's how it was to be done, the trolley capability would not be compromised. Might even be economic to put in the complete track support structure at the same time since the necessary construction structures and equipment would be there anyway.
I was thinking of this option also, for 2 reasons. One, jacking up the bridge would allow this unlikely location to keep its longest steel arch span in the world title, as well as allowing the larger ships to pass under, helping to boost the economic value and jobs numbers of the port and related industries. All this while connecting staten island with the mainland to the north with rail, cutting down the travel time if only an east/west connection were made. I would hope some sort of connection would be made also to 8th st station on the HBLR, thinking of the steinway trollies that were built specifically to save weight and allow practical engineering to carry them over the QBB in nyc. I think one of those "slim" takes on the PCC design such as are used in older cities with narrower streets might work... North shore SIRT line rebuilt to connect the whole shabang?
