Distance Redmond WA to Seattle WA Miles: The Full Breakdown

Fifteen miles doesn’t sound like much until you’re stuck on SR-520 at 5pm on a Thursday wondering why a “short drive” is taking 45 minutes. If you’re trying to figure out how many miles is Redmond from Seattle, and what to realistically expect once you’re behind the wheel, here’s everything worth knowing.

The distance Redmond WA to Seattle WA miles-wise lands right around 15 miles. Drive time swings a lot more than the mileage does — anywhere from 17 minutes on a clear afternoon to well over 40 during rush hour.

Detail	Information
Driving Distance	Around 15 miles
Best-Case Drive Time	17 to 23 minutes
Rush Hour Drive Time	30 to 45+ minutes
Main Routes	SR-520 (toll bridge) or I-90 (free)
Alternative	Sound Transit 545 bus, roughly 30-45 minutes

Two Routes, One Lake in the Way

Lake Washington sits directly between these two cities, so there are really just two practical ways across it for anyone weighing the Redmond to Seattle drive time. SR-520 is the more direct crossing and usually the faster pick outside of peak hours, but it’s a toll road with SR-520 toll price shifting depending on the time of day. I-90, a bit further south, skips the toll entirely and covers similar ground, though it can run a few minutes longer and gets its own share of congestion during commute hours.

Route	What You Get	What It Costs You
SR-520	Shorter, more direct	Toll, price varies by time of day
I-90	No toll	Slightly longer, still congestion-prone

Why the Drive Feels Longer Than 15 Miles Suggests

This isn’t a rural 15-mile stretch with open road the whole way. It’s a lake crossing connecting two of the busiest employment hubs in the Pacific Northwest — downtown Seattle on one side, the Redmond-Bellevue tech corridor on the other. Tens of thousands of people make some version of the Redmond Seattle commute every weekday, which is exactly why the mileage barely predicts the actual drive time. Locals plan around the clock, not the odometer.

When You’ll Actually Hit Traffic

Morning rush, roughly 7 to 9am, is worst for anyone heading toward Seattle. Flip that in the evening — 4 to 6pm sees the heaviest traffic heading back out to Redmond. Outside those windows, and pretty much anytime on weekends, the drive settles back down close to that 17 to 23 minute baseline.

Window	What to Expect
7am–9am weekdays	Heaviest traffic toward Seattle
4pm–6pm weekdays	Heaviest traffic toward Redmond
Midday and weekends	Close to best-case drive time

Skipping the Drive Entirely

Plenty of people covering this route don’t drive at all. The Sound Transit 545 bus connects Redmond and downtown Seattle directly, running about every 20 minutes for a few dollars a ride, with a total trip time of roughly 30 to 45 minutes depending on traffic. Rideshare is another option, usually landing between 18 and 28 minutes for somewhere around $40 to $60. For a daily commute, the bus tends to win on predictability, since it isn’t at the mercy of parking on either end the way driving is.

Option	Time	Cost
Sound Transit 545	30 to 45 minutes	Around $3
Uber or Lyft	18 to 28 minutes	$40 to $60
Driving Yourself	17 minutes to 45+ minutes	Toll on 520, free on I-90
