NW LNK Improvement Sketches 2: I-180 @ I-80 and Superior Street
I was recently in a situation where I was not allowed access to a computer, phone, books, etc. for several hours…but I had a couple pens and some handouts with blank backs! So for the next few weeks I will post these sketches. They are just some thoughts I’ve had about how I would improve roads in NW Lincoln. I did draw these 100% from memory; I did not alter anything afterward, and so once I look at satellite pics, that will probably nix some of my ideas. (Obviously not to scale for the same reasons.)
This was an attempt to redesign the two interchanges at the north end of I-180. They are very close together (not meeting modern Interstate standards!) and it looks like some preliminary work may have been done when I-80 was widened to redo this, so I took what little I had and ran with it. In addition to hopefully eliminating the dangerous area between the two interchanges, I also eliminated the cloverleaves leading to and from I-180 to help improve downtown access (and Memorial Stadium on game day).
I threw in a diverging diamond mostly for fun, although given that Superior Street is a primary route going east it might not be a bad idea to eliminate cross traffic turns.
