How Far Is Tacoma from Seattle? Travel Guide
The Short Answer
Tacoma is about 35 miles south of Seattle along Interstate 5. If traffic cooperates, you're looking at roughly 40 to 50 minutes of driving time. That's it. Not complicated.
But "about 35 miles" doesn't tell you much when you're actually planning a trip. The real question is how you're getting there and what the roads look like at that particular moment.
Distance by the Numbers
Straight-line distance (as the crow flies) is roughly 30 miles. But nobody drives through the atmosphere, so you care about road distance:
- Via I-5: About 34-36 miles depending on where you start/end
- Via US-99/SR 99: Similar distance, but slower and more lights
- Via water: About 25 miles by boat, if that's your thing
Most people take I-5. It's the obvious choice and the fastest option 90% of the time.
How to Get There
Driving Yourself
This is the most common method. You control the schedule, you stop when you want, and you don't have to coordinate with anyone.
Route: Jump on I-5 North from Tacoma. Stay on it for about 35 miles. Take the Seattle exit for wherever you're going—downtown, the stadiums, wherever.
Realistic time:
- Light traffic: 40-45 minutes
- Normal traffic: 50-65 minutes
- Heavy traffic (commute hours): 75-90 minutes
- Worst case (accident on I-5): 2+ hours
The stretch between Fife and Federal Way is notorious for bottlenecks. Add another 15-20 minutes if you're hitting it during rush hour.
Taking the Train
Sounder North runs between Tacoma and Seattle, but don't expect bullet-train speeds. This is a commuter rail, not a high-speed line.
One-way fare runs around $3-5. Travel time is roughly 1 hour. The schedule is limited—typically just a few morning and evening runs on weekdays. Weekends? Good luck.
It's reliable when it runs, but checking the schedule before you plan your life around it is mandatory.
Bus Options
Sound Transit 590/594 runs express buses along the I-5 corridor. These are your best bet for public transit between the two cities.
- Travel time: 50-70 minutes
- Frequency: Every 15-30 minutes during peak hours
- Cost: Around $3-5 with an ORCA card
The buses have WiFi and power outlets. You can actually get work done on the commute if you need to.
Rideshare or Taxi
Uber and Lyft are readily available between Tacoma and Seattle. Expect to pay $40-70 one-way depending on demand, time of day, and surge pricing.
Not the cheapest option, but convenient if you don't want to drive or deal with parking in Seattle.
Travel Options Comparison
| Method | Time | Cost | Best For |
|---|---|---|---|
| Driving (light traffic) | 40-45 min | Gas + tolls | Flexibility, hauling stuff |
| Driving (rush hour) | 75-90 min | Gas + tolls + sanity | Nobody. Avoid this. |
| Sounder Train | ~60 min | $3-5 | Commuters with fixed schedules |
| Express Bus | 50-70 min | $3-5 | Budget travelers, no car needed |
| Rideshare | 40-90 min | $40-70 | Special occasions, no options |
Getting Started
If you're planning a trip from Tacoma to Seattle:
- Check traffic before you leave. Use Google Maps or Waze. They're usually accurate about real-time conditions.
- Leave before 7 AM or after 9 AM if you're driving on a weekday. The 7-9 AM window is brutal.
- Consider parking costs. Seattle downtown parking runs $20-40/day. Factor that into your decision.
- Download an ORCA card if you're taking transit. It's accepted on buses, trains, and ferries throughout the region.
Things That Affect Your Trip
Construction: I-5 construction between Tacoma and Seattle is almost constant. Check the Washington State DOT website for current closures.
Weather: Snow and ice don't hit this corridor often, but when they do, I-5 becomes a parking lot. Winter trips require checking conditions.
Events: Seahawks games, Sounders matches, anything at the stadiums or Climate Pledge Arena—these add 30-60 minutes to your trip. Plan accordingly.
The Bottom Line
Tacoma to Seattle is a straightforward 35-mile drive on I-5. Budget 45 minutes in perfect conditions, 60-70 minutes in normal traffic, and longer if something goes wrong.
Transit is viable if you don't want to deal with driving or parking. The bus is more flexible than the train for most people's schedules.
