It's historically a horrible commute.
Very hard to predict too.
But they are currently attempting to help that commute with the 520 replacement project. That highway you are seeing on google maps to get across the lake is being replaced, and right now it's a toll bridge (which has lightened traffic actually.)
Hard to say what difference will be made.
I lived near Greenlake and had to commute to Redmond often for projects. I could randomly one morning leave at 6:30 AM and be in Redmond by 6:50.. next day I'd be running 5 minutes late, and leave at 6:35 AM, and wouldn't get to Redmond until after 7:30. Aggravating.
Thanks for the heads up...I've got a week and a half of living in Seattle before my job starts, I think I'll just have to get in a few practice runs until then. The only other option would be to take the Burke Gilman all the way to Redmond but that's 23 miles and would probably take twice as long...or I could just straight up drive (no idea how long that would take with traffic), but I'll be getting a free orca pass with work and would rather save on gas money.
