Ten years ago I did a similar commute, only in reverse. All I can say is on snow days, it will suck. There aren't a lot of viable North-South "back routes" in that area to disperse the traffic jams on 169. Otherwise, it wasn't too bad on most days.
It may get better soon, too, as they're looking at accelerating the plans to remove the stop lights on 169 at 494. They're talking about possibly building a standard cloverleaf interchange within the next 3-5 years, rather than waiting 8-10 years to fund a more complicated, expensive "flyover" interchange.
Plan to turn Hwy. 169 to freeway gains favor
PS: Seeing how well they take care of the bridges we already have (cough!), I'm all for the cloverleafs rather than the flyovers. Last thing we need is MORE bridges to maintain.
