Don't forget that there's a maximum grade the trains can go up and down. Part of the reason why the bridge goes over the river at 2nd St SW is to lengthen the bridge and lower the grade. You put the bridge a block closer to Centre Street and the portal to above grade has to be deeper into downtown and further from the river...

Use the 1st SW underpass. ie. permanently close the road to traffic. You'd have to dig it a bit deeper, but while you're at it you could make a much much better pedestrian underpass.
To make the turn off 11th you're going under the Circle K and it's surface parking lot. Compared to the 200 block where you're going under the 110 year old (make that 140 by the time we see shovels) Lewis Stationery Building...and then a whole new tunnel under CPR and the parkade ramp.
As for the river side, yes. Shorter, straighter, simpler, less uglier = cheaper. That's the point. The line can start coming up to surface north of 4 Ave, for a surface level station near Riverfront Ave, and then it would be a straight shot from Sien Lok Park to a portal around where the Crescent Hts pathway connects to Centre St. Exactly like E=NG has on both sides of their river bridge.
Added bonus is Sien Lok park would be a much better staging area on the south side of the river. No need for another 5 years of mess in the heart of PIP and a permanent eyesore (has anyone costed that?). Kill the stupid 9th ave station while we're at it, and we should be pretty close to affording another 1500 meters of cut+cover down Centre.
