So going back to the Minnehaha Parkway discussion...
As I mentioned a ways upthread, I live quite close to the intersection of Portland and the Parkway. We walk and bike the trails both directions from Portland all the time. Our children are almost-5 and just-past-2, so we're vividly aware of keeping little ones safe through that nasty intersection. We also drive it both directions regularly—heck, I use it as my primary access to/from 35W as I head to Edina for work every day (which, btw, I feel the need to disclose as the recommendation from MPRB would screw up my routine quite a bit).
Anyway, I've been brewing an idea for quite some time, and I'm ready to share it with the world. For reference, here is the Park Board's recommendation for the redo of that general area (page 2 in the PDF).

And here is mine:
- Split one-ways should turn over as much space to the creek and non-motorized users as possible.
- They should also end up providing more access to the park itself for people wanting to play, particularly EB.
- For the record, I live just north of the Creek, so sticking WB traffic on "our" side is a hard pill to swallow, but it's for the best IMO.
- Red indicates raised or specially-paved intersections. I'm aiming for the slowest possible traffic through those spots.
- The bike lanes on Portland, Park, and Chicago would be at curb height for a short distance past the intersections with the Parkway.
- Moving the walking trail north of the creek between Portland and Chicago allows for more room for stormwater handling on the south side.
- Taking advantage of the Parkway stub between Elliot and Chicago does the same.
- Everything is pretty darn close to at-scale. I spent a lot of time with the measuring tool on the Hennepin Co GIS site.
- 10' bike trail, 8' pedestrian trail, 6' sidewalks, 16' boulevards along the Parkway, etc.
- Small roundabouts: 42' diameter center, large one: 64'.
- Speaking of GIS, I very much intentionally used a map with property lines so we could see just how much space is theoretically available.
I tried to disperse traffic at the three-way intersection with 50th:
- Drivers heading south on Portland will probably end up using 51st.
- Drivers heading north on Portland will have several options: go around on the Parkway, take a left from 51st, go up 4th Ave, etc.
- Drivers heading east on the Parkway can go around or use 51st.
I tried to make Park Ave an enticing NB route:
- The roundabout should at least inspire drivers to go North instead of west to Portland before turning.
- That said, traffic heading north needs to go slower than the current raceway intersection. Again, roundabout.
OK, tear it to shreds.
