I work at Redmond. There are four centers -- Issaquah, Canyon Park, Bellevue, and Kirkland. Redmond covers all the Eastside, up to Stevens Pass (Woodinville, Monroe, Gold Bar, etc... not Snohomish though), and down to Issaquah and over to Snoqualmie Pass, to Bellevue and Mercer Island, north around the lake around Kirkland, Kenmore, Bothell, Lake Forest Park, the northeastern part of Seattle (generally 520 and north and I5 and east), Lynnwood, Mill Creek, etc. It's the biggest facility in the state... I think they do about 200=230 routes. They handle all the outbound loads from centers on their night sort and some inbound stuff (Seattle handles the rest of it). Doesn't take long to go driving because there are so many drivers leaving/retiring/going to feeders/etc.
