Around 3 hours, give or take 20 minutes. You can also take the Amtrack train straight from Portland to Tacoma, or Seattle. It takes generally the same amount of time, but I prefer the train, because it's more comfortable, and often cheaper than gas. I used to live in Gig Harbor, and now I live in Portland.

To Seattle
Google Maps estimates the driving time as 2 hours and 55 minutes.
The distance is takes to travel from San Antonio, Texas, to Portland, Maine is about 2 days and 23 hours. This also depends on the number of stops you make.
I don't believe there is train service from Seattle to Anchorage. If such service exists, it would cover about 2,500 miles and take about 2 or 3 days.
