The report also mentions a single tower cable-stayed design (225m main span, 160m side span, 80m tower or 180m main span, 125m side span, 65m tower) - a form we don't have yet in the Lower Mainland.
The "tied arch" structure is interesting.
The multi-span extradosed (structure shared by cables from short towers and by girders) bridge design is like the Canada Line and Golden Ears designs (not sure if Pitt River Bridge is extradosed).
My guess, however, is that a single tower design wouldn't work with a combined road-rail bridge.
