Yeah I'm very hopeful that the 35W/66th interchange will help set the standard for high-volume urban interchanges. The go-to for the past decade or two has been a massive diamond (see Cedar Fwy and E 66th St) or a SPUI (see Lake/Hiawatha, Lyndale/494, and Penn/494). Both require huge, expensive bridges (especially SPUI), the diamond is tedious to get through, and the SPUI is awful for pedestrians. I think it would be awesome if it set the stage for Lake St/35W; however, since 66th won't be completely done till 2018, it may to be too late to change the design at Lake St.BoredAgain wrote:Have they released any details on the dogbone/dumbbell for the 35W intersection(s)? I really wanted this to happen at 35W/Lake when they were planning the new transit station at that intersection. I think it would have greatly reduced queuing for the on-ramps and shortened pedestrian crossing distances. I think I sent that suggestion in too late in the process, but I doubt it would have been considered anyway. Instead, they are just making the turn-lanes even longer, which will not allow traffic get out of the way any more quickly.
Now, I'm just curious as to how they are planning to do it here. If successful, then it could point a way for future projects.
City staff posted a lengthy PDF including sketches of that dumbbell and background info here: http://ci.richfield.mn.us/modules/showd ... entid=6355. You can see the 66th St interchange on page 8. As you can see the space used under the bridge is significantly less, and even the impacts on the edges aren't too bad. However, city staff currently want to demolish the home at the NE corner, so that the alley can be rerouted. (They don't like dead-end alleys for snow clearing.)
