[IMG_1117] they are replacing a bridge/overpass and wanted to improve issues of cars exiting and entering the hwy onto 169. everything that is dashed is going away. so, there will be no on/off ramps to the south of this east/west road. i asked engineer about the design and he basically said it was…

If that interchange was busy, I see major congestion in the future. Was it?

hwy 169 is major 4 lane north/south route and has constant issues during rush hours. they could add separated merge lanes but then it goes from 4 lanes total to 6 lanes so interchange would need to be made wider. the main part of job is new bridge for hwy 9 which is over 169. so, remove merge choke …

I assume the engineer meant that they want to eliminate weaving, which is somewhat dangerous. See here if you don’t know what I mean: [image] Grade separation | Weaving On roadways with grade-separated interchanges, weaving is a result of placing an exit ramp a short distance after an ent…

[image] Barkydog: Jughandle road pattern. This is a very different usage of “jughandle” than the more common usage you’d see in places like New Jersey. What you show has some elements of a Michigan left, but it’s not really that either.

In 1966, when I took the MN written test for my learners permit, I seem to remember MN required no oncoming traffic for 500 feet. In as much as that was more than 50 years ago my memory may well be wrong.
