Here are my two thoughts, on these two subjects.
Regarding Angela-933: I actually prefer the new setup. Before the
rightmost lane would be filled with bozos who knew they had to merge
somehow, so they would be really stressed out and ready to gun it from
the light in order to bash their way in before the merge.
Now I just get in the one lane going straight with all the other
traffic, and when the light turns green I go ahead. Usually there are
only a few cars behind me, I swing wide to the right and slow in order
to let everyone pass, so it's all good. If I'm feeling fast, though,
and there are too many cars back to wait effectively, then I just take
the lane and bomb down the hill. The key there is to make it to the
merge before cars are tempted to pass dangerously, so I'd think for
most situations, the better option is to just swing right and let
everyone pass.
An alternative to that intersection is to turn left on Leeper (last
street before the light), then take the bike lanes on Northside.
Leeper is such a useful street for bikes.
Regarding lack of lane definition: I'd like to think those roads are
actually one lane each way, consisting of a "wide curb lane" (WCL) or
"wide outside lane". With low enough traffic volume such that cars
don't attempt to double up, WCLs can actually be very pleasant to ride
on. Many cyclists actually prefer them to other, segregated "separate
but equal" infrastructure like bike lanes or multiuse paths (MUPs).
In fact, I consider Edison between 933 and Notre Dame Ave to be an
excellent example of how a WCL can make for a great ride. (Especially
in contrast to the MUPs west of Notre Dame Ave, which aren't really
suitable for bike traffic IMHO.)
But many of these quasi-WCL roads seem to turn into 4-lane arterials
at intersections. Jefferson east of Eddy is awful about that.
Ironwood between Edison and the river is another example: delightful
WCL at Corby/Rockne, nasty 4-lane squeezed in at the newly repaved
McKinley intersection.
Between stoplights cars generally travel single-file, making a
delightful WCL. At many intersections, though, it seems they're
encouraged to line up double-file. So, yeah, I don't really
understand what the planners/engineers are thinking there. Maybe one
team is responsible for designing the stoplights and another team is
responsible for the striping and design of the streets?
