Vantage is not that steep, IIRC going west is in the 4-5% range. Being as it is an interstate, per federal road building guidelines, it can not be steeper than 6 with sort bursts to 8%. If you want as steep a climb on an interstate as you can get, drive the Road from Ellensburg to yakima. HWY 80?!?!? That is as steep as one can make an interstate hwy and get federal funding.
I pulled the west and east vantage grades at 52 mph with a blinken 6.5td at 15K lbs, 2000 over gcwr! and an overheater at that! so it could not be that steep etc! Granted it is long, ie 5-10 miles or so.
Now queen anne ave in parts of seattle.......one block I know of is 24.5%, that is a STEEP HILL! 5% is one of them, there was a hill back there?!?!?!?!?!?
