Tunnel Ride

Tunnel Ride: SR 99 Grand Opening

Sunday, February 3, 2019

First chance to ride inside the new SR99 Tunnel and last chance to ride on the Alaskan Way Viaduct!

Bertha bore the way…Ride inside the new SR99 Tunnel before it opens to cars – and since the Alaskan Way Viaduct is still standing, bike these two routes together before the viaduct is demolished!

Registered riders will receive a free commemorative souvenir, and t-shirts will be available for purchase. A portion of the revenue from bike ride registrations help support the Step Forward weekend activities.

This bike ride is part of the big weekend celebration. There's also a Tunnel to Viaduct fun run on Saturday, Feb. 2. For details about the run and other activities, visit 99 Step Forward
