Tolling on the SR 520 Bridge is expected to raise $1.2 billion to help fund the replacement bridge opened in April 2016. It also helps manage congestion on the SR 520 corridor.

Toll Rates

Toll rates vary by time of day and are collected in both directions. See toll rates.

There are 47 signs on SR 520 (pdf 241 kb), and the roads leading to it on either side of the lake, advising drivers that a toll road is ahead and what their last exit will be before paying a toll.

Ways to Pay

The SR 520 Bridge is an all-electronic tolling facility; there are no toll booths.

  • A pre-paid Good To Go! account is the cheapest and most convenient way to pay for tolls when you travel frequently on the SR 520 Bridge.
  • If you don't have an account, you can Pay By Mail for $2 more. We'll take a photo of your vehicle and send the vehicle's registered owner a toll bill in the mail so you don't need to stop driving.


Buses, vanpools and emergency vehicles are able to travel toll-free if they meet specific requirements.

Carpools and motorcycles pay tolls just like all other personal vehicles.

Future Plans

Construction continues on the SR 520 Bridge Replacement and HOV Program.

Tolls on the SR 520 Bridge are paying off 30- and 40-year bonds. After the bonds are paid off, the Legislature will decide whether to continue tolling the bridge.
