Bicycles and pedestrian routes

Bicycle and pedestrian routes will change during construction, but crews will maintain clearly marked paths, and outreach staff will continue to work with local bicycle and pedestrian organizations to communicate changes.

Tunneling machine unloaded, path restored to pre-Bertha configuration

Now that crews have finished unloading Bertha, the world's largest tunneling machine, the path to the west of our south-end work zone has been restored to the configuration it was in just before the machine arrived in early April. That means the interruptions to access that occurred during unloading will no longer occur. The west sidewalk remains closed between South King Street and Yesler Way.

Foot traffic along the path has increased as people try to catch a glimpse of the machine and the work that's occurring near the tunnel launch pit, so please use caution as you're passing through. Thank you for your continued patience. If you have questions or concerns, please email viaduct@wsdot.wa.gov or call us at (888) AWV-LINE (298-5463).

Future access

Bicycle and pedestrian improvements are an important part of our work to replace the viaduct. So far crews have built:

• A new multi-use path along the west side of Alaskan Way South, between South King and South Atlantic streets.
• New bike lanes on East Frontage Road South.
• New sidewalks on Railroad Way South, First Avenue South, South Royal Brougham Way, South Atlantic Street, and Colorado Avenue South.

Future improvements include a new 12-foot-wide bicycle and pedestrian path on the north side of South Atlantic Street, between Utah Avenue South and Alaskan Way South. This new connection will link bicyclists and pedestrians to the trail network in downtown and beyond. Permanent bicycle improvements along the downtown waterfront will be designed as part of the City of Seattle’s Waterfront Seattle project.
