Used to work out of US Gipsum on Riley Road with the off ramp so steep going down to the bottom of the hill with a loaded semi in winter wasn't fun.The section that started at Riley Road went across the river is gone. The section that is on top of Dock Street is still there. Going north from Riley road you can still get one to get off at calumet of onto the IN toll road/Chicago Skyway.
Sadly the "majestic" part which was the highway in the sky with the "L" shape curve is no more. As a teenager I would get on Cline from 80/94 and drive all the way to the calumet exit in a very, very, very short amount of time. Stupid and fearless back then. The funnest part was that "L" shape curve and passing other cars why they hit the brakes and being so far up.
