Bike on I-5, the Aurora Bridge and the soon-to-be-closed waterfront Viaduct April 8

Cascade Bicycle Club's Emerald City Ride 2018 won't ever be repeated because part of the route will be on the slated-for-demolishion Alaskan Way Viaduct.

The third annual Emerald City Ride sticks with the theme: Bike on freeways typically off-limits to biking. And 2018 is shaping up to be one of the best routes yet. Rather than crossing the 520 Bridge as in the two previous years, the April 8 ride will start with a ride across the Alaskan Way Viaduct downtown, then continue on Aurora all the way to Fremont before taking city streets past Gas Works Park and onto the I-5 Express Lanes back to Sodo. The I-5 Express Lanes alone are reason enough to register.

Speaking of registration, the 12-mile full ride is $40 for adults with discounts for youth and Cascade members. You have until April 4 to register online. Day-of registration may be available for an extra $10, but only if they don't sell out online. So since this is probably your last chance ever to bike on the Viaduct, I wouldn't wait.

If you just want to bike on the Viaduct, you can register for a shorter 3-mile "Viaduct Experience" ride for $25 (again, discounts for youth and members).

Check out our post from last year's ride for an idea of what you're signing up for. It's worth the cash.
