Alternate Routes

If you don't know it already, the SR520 bridge is at best, a poorly disguised parking lot. It takes nothing to cause it to switch functions.

Before you attempt crossing Lake Washington this way, check the WSDOT traffic web  to see if the bridge has already become a parking lot. Listen to the traffic reporters on the radio or use your GPS device to monitor traffic conditions. If SR520 is stopped, your alternate routes are to drive around the north end of Lake Washington (Lake City Way), or to use I-90. I-5 north to I-405 south also works; it's about the same between driving further at freeway speed and the shorter route on surface streets.

If you are already south of SR520, use I-90 to cross the lake, and then go north on I-405 to connect with SR520. Even if you are not south of SR520, it can be worthwhile to take the "long way" via I-90. I-90 has more capacity, and it has HOV lanes if you're carpooling.

SR520 Bridge Toll

The SR520 floating bridge now is a toll bridge.
  • If you have established an account with the WSDOT, then your account will be dinged when you cross the bridge.
  • If you have an account, but don't have the RFID transponder, then your crossing will cost another $0.25.
  • If you don't have an account, and you cross the bridge, WSDOT photographs your license plate and they will mail you a bill for the crossing. This option costs $1.54 additional beyond the toll.
