We’d like your feedback on our “Rest of the West” design recommendations
Last week WSDOT and the city of Seattle released a draft design report containing the final conceptual design recommendations for improvements to the SR 520 corridor in Seattle. Planned but still unfunded improvements in this west side section of the highway include a new Portage Bay Bridge, the new west approach bridge south, lidded overpasses in the Montlake and Roanoke neighborhoods, and enhanced facilities for bicyclists, pedestrians and transit riders.
Got an idea or opinion to share about the design? We love residents taking an interest – tell us what you think! The official public comment period is open, and will run through Feb. 13. You can review the full final report here (as a 22.5 mb PDF) or find it on our website split into smaller bites (better for the digestion).
We have developed a short survey for people to fill out in response to the report.
If you wish to provide your own free-form comments, you can submit them via e-mail or snail mail:
- Email: SR520Westside@wsdot.wa.gov
- Mail: SR 520 West Side Project, SR 520 Program Office, 999 Third Ave., Suite 2200, Seattle, WA 98104
Thanks for your participation as we finalize plans and seek funding for the Rest of the West!

WSDOT releases updated design concepts and cost estimates for remaining SR 520 improvements in Seattle
WSDOT today (Jan. 16) released design and cost updates for completing the planned but still unfunded SR 520 improvements in Seattle between I-5 and Lake Washington. The final draft design concepts were developed in close collaboration with the city of Seattle and local stakeholders. Key design features include:
- A new Portage Bay Bridge between I-5 and Montlake, designed to better fit its surroundings and resist earthquakes.
- New HOV lanes from I-5 to Montlake.
- Highway lids at Montlake Boulevard and 10th Avenue East/Delmar Drive East that help reconnect neighborhoods and provide transit facilities.
- The south half of a new west approach bridge built to modern seismic standards, for carrying eastbound traffic from Montlake to the new floating bridge.
- Mobility improvements such as bicycle, pedestrian, and transit connections and networks to and from SR 520 to existing and planned city networks, including options for users of all ages and abilities and safer undercrossings.
- An extension to I-5 of a regional bicycle and pedestrian path from Seattle to the Eastside, with connections to local trails and transit stops.
The revised cost estimate to complete the “Rest of the West” is $1.57 billion. A 2012 estimate put the cost at $1.4 billion. The increase since 2012 is due in part to rising construction costs in a robust economy. The new cost estimate puts the total cost of the SR 520 construction program at $4.47 billion, which is $180 million below the SR 520 budget cap set by the Legislature in 2009.
We’ll be briefing state legislators over the coming weeks about the new designs and cost estimates. If funding is provided this year, we could move into final design work.
The official press release and full design report are available on the SR 520 website. You can learn more online about the updated cost projection for completing the “Rest of the West.”
Construction activities in Montlake
Construction crews are doing more work in the Montlake area in January, including some noisy work taking place at night. For more information, read the West Approach Bridge North construction update and sign up to receive future WABN e-mail updates.
SR 520 year-end review hitting your mailbox
Our 2014 year-end review mailer drops this week (into your mailbox, not onto the Billboard Top 40). It recaps a year of great progress and important milestones for the SR 520 construction program. We strive to keep you informed about the what’s and the why’s of construction. So we thought we’d send you a link to the mailer’s online version in case your mail carrier is on vacation or you want to forward the brochure to a friend. Thank you to everyone who has read our emails, attended public meetings, Tweeted us questions or otherwise engaged with the program.
