Isn't it funny how the Fisher lane seperation (between local and express) is never mentioned, while the Jeffries seperation is? Is there some kind of technical definition that prevents the Fisher lanes from formally being designated express-local? BTW, just for what it did to Corktown I curse that section of the Fisher. It looks like a wasteland because of the overbuilt freeway. I get you need all of the capacity because you're connecting the bridge to the northern suburbs. But, there had to have been some other way to do it. Maybe simply have directed the truck traffic up the Jefferies, and made them go up to the Ford, and
then cutting across and connecting to the Chryslere to get them north?

Usually it's much cheaper and more compact to send one road above grade and one below

Yeah, you go two miles down Woodward where it crosses 8 Mile, and that's the interchange you get. Woodward express lanes are an above grade bridge, the local lanes of both Woodward and 8 Mile are at grade, and 8 Mile express lanes below grade.
