Best semi route from Chicago to Seattle? I80 or I94

I would do the 94 across but than I have went that way for 35 plus years

 

I've only gone down 94 a couple of times; there ain't NUTHIN' up there! I spent a couple years working inside a carrier as a nation-wide night time road breakdown agent, and I remember one time a driver was having reefer issues on I94 (he decided to take it rather than 190 just out of curiosity), and I couldn't find one single reefer repair facility until Fargo; he ended up having to run all night and even a couple of hours over legal service hours to save his load.

So, yeah, there's a good reason why not many people take I94.....

 

Or skip pulling reefer.

 

All the better for me.
