What's the best way to move between Seattle and the Eastside?

Timing the bridges is everything — your chauffeur knows when the 520 and I-90 are flowing and routes around the worst, so a Seattle-to-Bellevue or Redmond run stays predictable.

When does Seattle traffic peak?

I-5 and the bridges stack hardest during rush hour and around stadium events. A scheduled pickup with a local chauffeur is the reliable way through it.

Do you serve the tech campuses and both downtowns?

Yes — rides between Seattle, Bellevue, Redmond, and the campuses, plus airport transfers, all at flat rates with the same chauffeur standard.

Getting Around Seattle & the Eastside

By the Koast Team · June 2026 · 4 min read

Seattle is really two cities: the downtown core and the Eastside tech corridor — Bellevue, Redmond, Kirkland — with Lake Washington in between. Your whole transportation experience comes down to when you cross it.

The bridge rule

Two floating bridges — the 520 and I-90 — carry everything between the halves. Midday they're a breeze; at the wrong hour they're parking lots with a view of the lake. Locals plan meetings around crossings the way they plan around the rain: with quiet fatalism and good timing.

The runs that matter

Sea-Tac → downtown — 25–40 minutes; the light rail is decent solo, a car wins with luggage or colleagues
Sea-Tac → Bellevue/Redmond — 30–50 minutes; no direct rail, this is car territory
Campus-to-campus days — investor and partner visits often hit both sides of the lake; an hourly charter absorbs the bridge variance

Rain reality: Seattle drizzle barely slows traffic — but the first real downpour of fall reliably breaks it. Book ahead in October.
