9:30am on a Tuesday, eh? I bet they will have an overflow crowd.

I went for the first 1.5 hours or so.  

Snippets from my scribbled notes:  You may be aware there are two phases yet to go:  Phase IV, crossing the Lester River to Highway 61; Phase V, actually crossing 61.  Construction is reportedly most likely to begin on Phase IV in summer 2012, but might start next summer.

The most promising scenario for Phase IV involves replacing the existing utility bridge next to the railway bridge with a new bridge, then hanging the utilities off of the new structure -- if that goes through, which it seems like it ought to, then the summer 2011 time frame might be more do-able.

For Phase V, things get more complicated.  They may have subsequently come to some new conclusions that will appear in tomorrow's DNT, but this was what I heard.

There were two main ideas advanced:  [see half-assed map]

a) a tunnel, down off 61st Avenue East, which would be converted to solely non-motorized traffic.  The tunnel would cut from around the end of 61st Avenue East northeast to the nearest corner of Brighton Beach.  The plan I heard discussed anticipated that the tunnel would have to be about 350 feet long.

b) a bridge, sited slightly east, along an existing non-used street right-of-way east of the EPA complex.  The problem here is the grade: the bridge would have to have at least 15' clearance; the west side of Highway 61 is significantly higher than the east side, so you'd have to scrub off a lot of "y" in a fairly small landing zone on the east side of 61, with imposed limits on the allowable grade.  Given the constrained space, this would probably require either switchbacks, a helical ramp, or something along those lines.  One back-of-envelope calculation someone suggested was that the "ramp" would have to be c. 600 feet in length to get from the crossing height to the exit level at an allowable grade.  

Eventually, some people started talking about just reworking the whole west entrance into Brighton Beach, running Hwy 61 over a bridge while taking 61st Ave E. underneath, with the Lakewalk accompanying it alongside.

I don't pretend to have heard/understood everything, or taken perfect notes, but you get what you pay for.
