Wondering what bridge to take? Check this out

SEATTLE -- Seattle traffic can be complicated and costly especially when you have to cross the bridges.

Ever wish there was an easy way to tell which route to take?

Its time for you to take a trip to your friendly neighborhood app store (free for Android and iOS) to pick up 520or90.

Its simple, launch the app, choose which direction you're going - Seattle to the eastside (Issaquah, Bellevue, or Redmond) or the reverse and press "Compare Bridges."

It tells you - in real-time - how much you'll pay not only for tolls but for fuel based on how the traffic flows.

Double plus bonus? It was developed a couple years ago right here in the Emerald City during Seattle Startup Week.
