I thought the limit goes up to 70 just south of Oly. Unless something has changed. I think it is still 70 from that point down to Vancouver. If not, it is a recent change...

Not true. Many western states allow speeds of 65 and 70 on two-lane roads. (Washington, Idaho, Nevada for sure). But perhaps I missed your point about east of the Mississippi.

Eastern Washington on I-90 and I-82 should be 75, not 70 as these roads generally are rural. Idaho has 80, and so does Utah and Montana. Gov. Inslee vetoed 75 a year or so ago, probably because that 5 MPH increase would increase climate change. (jeesh). Oregon still has only 65 on I-5, but has increased I-84 in Eastern OR to 70.

Iowa has historically been one of the slowest states west of the Mississippi, and it doesn't make much sense to me. The majority of roads are straight, fairly flat, and there just isn't much to impair visibility. Our rural speed limits are extremely cautious and simply don't make sense in this day and age.
Iowa is painful. Going from 80 mph in South Dakota, down to 55 in Sioux City, and then 70 the rest of the way. Ugh!

I'm good with South Dakota limits. Most of I-90 and I-29 are 80 mph, outside Rapid City and Sioux Falls, where it's 65. From just west of Rapid to the Wyoming state line, the limit is 75. Many rural highways are 60-70.

This is true. Texas leads the way with 75 mph speed limits on 2 lane roads in many parts of the state.

You are correct. 75 was the maximum speed in Iowa before 1974.

When the oil embargo started in late 1973, some states dropped their highway speed limits to 50 mph.

When they were drafting legislation for the NMSL, the speed limit was initially going to be 50 mph for cars and 60 mph for trucks and then they settled on 55 mph instead.
