Do I Need Good To Go! for Washington? 2026 Update

No - but you'll pay more per trip without one. Washington operates 5 all-electronic toll facilities. There are three payment tiers, not just two: a Good To Go! pass gives the lowest rate; registering your plate on an account without a physical pass ("Pay By Plate") costs an extra 25 cents per trip; and having no account at all ("Pay By Mail") costs an extra $2.00 per trip, billed to your vehicle registration address. All facilities are cashless.

Key Reality: Without a Good To Go! pass, you pay Pay-by-Mail rates - $2.00 higher per trip than the Good To Go! pass rate at SR 520, SR 99, Tacoma Narrows, and I-405. For daily commuters, this adds up to $500+ per year. HOV requirements for free travel on I-405 and SR 167 vary by facility and time of day - see the HOV section below, since it's not a flat 2+ rule everywhere.

2026 Update: E-ZPass is not accepted in Washington - Good To Go! is the only accepted transponder system, and there is no interoperability agreement with E-ZPass or any other state's system. Visitors and infrequent drivers can open a temporary Good To Go! account online at mygoodtogo.com, valid for up to two weeks, using just a license plate number and credit card - no physical pass required.

How to Pay Washington Tolls

1. Good To Go! Pass (Cheapest tier):

• $10 initial setup fee (applied to account balance); $15 minimum balance required
• Available online at mygoodtogo.com or at participating retail locations
• Works on all 5 Washington toll facilities; lowest available rate
• Required for HOV-free travel on I-405 (with the peak-hour 3+ occupant rule) and needed to avoid solo-driver tolls on SR 167
• Visitors: temporary accounts available online, valid up to two weeks, license plate + credit card only

2. Pay By Plate (Middle tier - often overlooked):

• Register your license plate on a Good To Go! account without installing a physical pass
• Costs just 25 cents more per trip than the pass rate - much cheaper than full Pay By Mail
• A good option if you don't want a physical transponder but still want to avoid the full $2.00 Pay-by-Mail surcharge

3. Pay By Mail (No account - highest tier):

• Automatic license plate recognition; invoice mailed to the registered vehicle owner
• $2.00 per trip surcharge above the Good To Go! pass rate
• Pay online at mygoodtogo.com within the invoice deadline to avoid additional fees
• Out-of-state and rental vehicles are also invoiced via their registered state/company
• To use SR 167 HOT lanes as a solo driver, you must open an account and install a pass - Pay By Mail alone is not an option there

4. Cash: Not accepted at any Washington toll facility. All facilities are fully cashless.

Washington Toll Facilities (2026)

SR 520 Floating Bridge (Seattle to Bellevue): Officially the Governor Albert D. Rosellini - Evergreen Point Floating Bridge, opened in its current form in 2016. Connects Seattle (I-5) to Bellevue and the Eastside via Lake Washington. Tolled in BOTH directions - as per WSDOT and the Washington State Transportation Commission; the toll is not one-directional. Dynamic/variable pricing from roughly $1.25 to $5.50 depending on time of day; lowest rates on nights, weekends, and holidays. Vehicles with more than two axles pay a pro-rated higher rate.

SR 99 Alaskan Way Tunnel (Downtown Seattle): A bored tunnel under downtown Seattle, opened February 2019, replacing the Alaskan Way Viaduct. According to WSDOT: tolled in both directions. Dynamic pricing roughly $1.25-$2.25.

Tacoma Narrows Bridge: Twin suspension bridges spanning Puget Sound, connecting Tacoma to Gig Harbor (Kitsap Peninsula). As per WSDOT: tolled EASTBOUND only - the direction traveling toward Tacoma, not toward Gig Harbor. Fixed rate: $4.5 Good To Go! / $6.5 Pay-by-Mail for 2-axle vehicles; higher for multi-axle trucks.

I-405 Express Lanes (Bellevue to Lynnwood/Renton): Managed express lanes on the primary Eastside north-south corridor; dynamic pricing $0.75-$10.00. Carpools and motorcycles must have an active Good To Go! account and the correct pass to travel free - during peak hours specifically, carpools need 3 or more passengers, not the commonly-assumed 2+.

SR 167 HOT Lanes (Auburn to Renton): High-Occupancy Toll lanes connecting Auburn to the I-405 Renton junction; dynamic pricing. Per WSDOT directly: all carpools must have a Good To Go! Flex Pass (set to HOV mode) and motorcyclists must have a motorcycle pass to ride for free

Frequently Asked Questions

Can I use E-ZPass in Washington?

No. Washington uses only its own Good To Go! system. E-ZPass transponders from any other state are not accepted on Washington toll facilities, and there is no interoperability agreement in place with E-ZPass or any other state's toll system. Get a Good To Go! pass at mygoodtogo.com before your trip, or open a temporary account as a visitor.

Do motorcycles pay tolls in Washington?

Motorcycles must pay standard tolls on the SR 520 Bridge, SR 99 Tunnel, and Tacoma Narrows Bridge

How do carpool discounts work on I-405 and SR 167?

They're not the same rule. On I-405, carpools need an active Good To Go! account and pass to travel free, and during peak hours specifically require 3+ passengers, not 2+. On SR 167, per WSDOT, only solo drivers pay a toll at all - carpools and motorcycles travel free without a peak-hour occupancy increase. There is no HOV discount on SR 520, SR 99, or Tacoma Narrows Bridge.

Which direction is the SR 520 Bridge toll charged?

Both directions. Confirmed directly by WSDOT and the Washington State Transportation Commission: "Tolls are collected for both directions of the bridge." There is no free direction on SR 520.

Which direction is the Tacoma Narrows Bridge toll charged?

Eastbound only - the direction heading toward Tacoma. Confirmed directly by WSDOT: "Tolls collected only in eastbound direction." Westbound travel toward Gig Harbor is free.

Are there free alternatives to Washington toll facilities?

For SR 520, the I-90 bridge is free but adds 10-30 minutes. For SR 99 tunnel, surface streets through downtown Seattle are free but significantly slower. For Tacoma Narrows, there is no free alternative bridge crossing of Puget Sound in that area.
